Each section contains an overview of the characteristics common to all primitives within that category. Primitives are grouped into classes within each category - one class of primitive serving a similar purpose at different sizes or resolutions. For each class of primitive, a brief description of the purpose of the primitive is provided, with notes on its co-ordinate origin, default size and rules for scaling. A list of the available primitives is shown.
'''Nomenclature'''


An understanding of the orientation of the co-ordinate axes is essential for authoring a part for LDraw. For reference within this page the axes and their direction is shown in this diagram.
Boxes are named boxF, with F representing the number of faces a box has. The suffix E represents the number of edges removed.


[[File:Xyzaxes.png|thumb|alt=Axes|Axes]]
F and E are may followed by an additional letter. The hyphen is removed if F is accompanied by a modifier.


'''Rectilinear primitives'''
Face modifiers:
 
* o - faces are opposite to each other
* t - faces are all touching each other (usually, it's implied, but box4t.dat is a thing)
* u - missing faces form a U-shape
 
Edge letters:
 
* p - groups of edges are parallel to each other
* a - some missing faces have no adjacent edges
 
'''Scaling and orientation'''  


These rectilinear elements may be scaled in the {x}, {y} and {z} dimensions to make elements of any size. For example
These rectilinear elements may be scaled in the {x}, {y} and {z} dimensions to make elements of any size. For example

LDraw represents curved surfaces as polygons. For circular components two series of primitives are provided.
 
All the circular primitives are orientated in the {x,z} plane with their origin at the centre of the circle and a default radius of 1 LDu. Primitives are provided for complete circles and for commonly used fractions of a complete circle. Where the naming convention includes a prefix of the form n-f this indicates the fraction (n/f) of the circle drawn by the primitive. Where this fraction is less than an entire circle, the primitive starts at {+x,0} and progresses in a conterclockwise direction when viewed from above {-y}.
 
To avoid rounding errors, it is preferable to use existing fractional circular primitives, or create a new primitive, rather than rotate an existing primitive by anything other than 90 or 180 degrees. For example, use 3-16XXXX.dat rather than combining 1-8XXXX.dat with 1-16XXXX.dat rotated by 22.5 degreees.

To avoid matrix arithmetic problems in some renderers, the third dimension ({y} in the default orientation) of two-dimensional primitives must be given a non-zero scaling factor.
LDraw circles are normally formed of 16-sided polygons (hexdecagons) - the regular resolution. For larger elements, where scaling-up of hexadecagons would give too angular an appearance, a series of high resolution primitives based on a 48-sided polygon are available. These may also be used for parts not well suited to a 16-fold symmetry.
 
These circular elements may be scaled by the same factor in both the {x} and {z} dimensions to make circular elements of greater or less than 1LDu radius. For example
 
1 16&nbsp;&nbsp;&nbsp;&nbsp;0 0 0&nbsp;&nbsp;&nbsp;&nbsp;3 0 0&nbsp;&nbsp;&nbsp;&nbsp;0 1 0&nbsp;&nbsp;&nbsp;&nbsp;0 0 3&nbsp;&nbsp;&nbsp;&nbsp;4-4edge.dat
 
would generate a circle in the {x,z} plane with a radius of 3LDu.
 
They may also be scaled asymmetrically in the x and z dimension to make ellipses.
 
Although the default orientation is in the {x,z} plane the LDraw language allows for these to be transformed
 
1 16&nbsp;&nbsp;&nbsp;&nbsp;0 0 0&nbsp;&nbsp;&nbsp;&nbsp;0 1 0&nbsp;&nbsp;&nbsp;&nbsp;3 0 0&nbsp;&nbsp;&nbsp;&nbsp;0 0 3&nbsp;&nbsp;&nbsp;&nbsp;4-4edge.dat&nbsp;&nbsp;&nbsp;&nbsp;would generate a circle in the {y,z} plane
 
1 16&nbsp;&nbsp;&nbsp;&nbsp;0 0 0&nbsp;&nbsp;&nbsp;&nbsp;3 0 0&nbsp;&nbsp;&nbsp;&nbsp;0 0 3&nbsp;&nbsp;&nbsp;&nbsp;0 1 0&nbsp;&nbsp;&nbsp;&nbsp;4-4edge.dat&nbsp;&nbsp;&nbsp;&nbsp;would generate a circle in the {x,y} plane

| [[File:4-4edge.png|200px|alt=4-4edge]]
||  This suite of primitives are used correct for gaps that form between curved primitives and normal geometry in editors that utilize primitive substitution. This is a special case used on the inside of a curved primitive where it joins geometry that cannot make use of a curved primitive. The chrd files themselves are simply a reference to empty.dat, which under normal circumstances does not draw anything. However, in tools that support primitive substitution, the curved primitive it is attached to would normally in this case create a gap when rendered using more than 16 points to form a circle. In that case, the substituted version of these normally empty primitives would fill in the gap between the curve and the other geometry.
 
To "see" these primitives, the editor in use must utilize primitive substitution. Then one of the following can be done:
 
* set the curve quality to a level high enough to see the gaps reappear
* For LDView 4.4 or later, in the Model Tree dialog, you can search for them (for example, "ering"), and if you have it set to highlight, then when you select one, it will be highlighted in the 3D view.
* Manually recolor the primitive in question to a color that contrasts with the colors that surround it
 
Note that the bounding circle in the image is for context only - there are no actual geometry producing lines contained in these files.

|| This suite of primitives are used to generate circular rings or part rings. The numeric suffix r in the filename indicates the inner radius of the ring - the outer radius is 1LDu greater. For example a n-f4-4ring4 primitive would create a ring with an inner radius of 4LDu and an outer radius of 5LDu.
 
Note: The correct nomenclature is to use the full word "ring". All newly created ring primitives must use "ring". Official files using "rin" have been obsoleted. All files using "ri" or "rin" have been moved, to use "ring".

||These primitives are used to generate cylinders or part cylinders which are truncated by a plane which is not perpendicular to the axis of the cylinder. The default angle of the plane is 45 degress.
 
These primitives are notoriously difficult to describe and the user is encouraged to experiment in order to gain a full understanding of their geometry. One technique is to open the primitive in LDPE and choose random colours. Selecting Show Axes also helps.
 
The 2-4cyls.dat primitive is orientated with the perpendicular bounding plane at the top {-y} and the angled bounding plane at the bottom {+y}. In common with the other 2-4xxxx.dat primitives, the {+z} semicircle is represented. By default the truncation plane is y=x-1. The 1-4cyls.dat and 3-8cyls.dat primitives are sub-sections of 2-4cyls.dat
 
The 1-4cyls2.dat primitive is orientated with the perpendicular bounding plane at the top {-y} and the angled bounding plane at the bottom {+y}. Unlike the other 1-4xxxx.dat primitives, the {-x,+z} quadrant is represented. The truncation plane is y=x.
 
The following observations may help :
 
1-4cyls and 1-4cyls2 are complements. If you put them together correctly they make a 1-4cyli.

||This suite of primitives are used to generate circular torus sections. By default all these primitives produce a torus with a major radius of 1LDu, so typically need to be scaled up in the {x} and {z} dimensions. The first character denotes whether the minor radius is smaller than (tff primitives) or larger than the major radius (rff primitives). The latter are termed reverse ratio tori. The second and third characters of the filename ff denotes the sweep of torus, as an inverse fraction (01=1/1, 02=1/2, 04=1/4, 08=1/8, 16=1/16, 32=1/32, 48=1/48). The fourth character denotes the section of a torus (i=inner, o=outer, q=tube - the combination of 2 inner and 2 outer sections). Inner sections are not possible for reverse ratio tori.
 
For regular tori, the last four characters of the file name rrrr denote the torus minor radius in LDu (1333=0.1333, 3333=0.3333), with the special designation 'unit' unsed to indicate a radius of 1.0000.
For reverse ratio tori named like rfforrrr.dat, the last four characters of the file name rrrr represent torus minor radius with an implied decimal point after the first digit (1500=1.5, 4600=4.6). For reverse ratio tori named like rfforrrrr.dat, the last five characters of the file name rrrrr represent torus minor radius with an implied decimal point after the first two digits (11000=11.0).
 
These diagrams (based on an idea of Paul Easter's) illustrate the relationship of the torus primitives to the major and minor radii.

==Stud primitives==
<div class="mw-collapsible">
 
Each studxxx primitive described below has a matching low resolution stu2xxx primitive, used by the fast-draw mode of renderers - these stu2xxx primitive must never be used in part files. An additional primitive (studline.dat) is used to substitute a single line for studs by the super fast-draw mode of LDraw.
 
All stud primitives are modelled with the solid disc uppermost, even if designed for the underside of parts (stud3, stud4, stud8, stud11). The origin is at the base of the stud and they extend for 4LDU in the {-y} dimension. To use for the underside, the primitives need to be inverted in the {y} dimension, viz.
 
1 16&nbsp;&nbsp;&nbsp;&nbsp;x y z&nbsp;&nbsp;&nbsp;&nbsp;1 0 0&nbsp;&nbsp;&nbsp;&nbsp;0 -1 0&nbsp;&nbsp;&nbsp;&nbsp;0 0 1&nbsp;&nbsp;&nbsp;&nbsp;stud3.dat
 
These primitives must not be scaled in the {x} or {z} dimensions. Ideally they should not be scaled in the {y} dimension either, to allow the accurate substitution of chamfered studs by high-quality renderers [but this rule is flouted in the regular brick files, where stud4 is scaled by 5 to generate the underside tube].

'''Text primitves'''
 
The section comprises reusable glyphs for constructing text patterns. These primitives may be re-sized.
 
The naming convention for these primitives is typeffci, where ff is an arbitrary two-letter abbreviation for the typeface, c is the glyph class (u=upper case letter, l=lower case letter, n=number, s=symbol, a=accented letter) and i is the glyph identifier (a-z for the upper and lower case letters, 0-9 for the numbers).

LDraw Primitives Reference

Latest Update: 16.11.2024, added the LDraw 2024-09 primitives.

This page is a source of reference for the LDraw primitives in the \LDraw\p directory. Primitives are defined as highly re-usable components of LEGO parts modelled for LDraw. They serve several purposes :

  • To speed up parts authoring by providing a library of components which can be incorporated into several parts
  • To allow rendering software to make substitutions of curved components

Within this reference material the available primitives are categorised into:

Each section contains an overview of the characteristics common to all primitives within that category. Primitives are grouped into classes within each category - one class of primitive serving a similar purpose at different sizes or resolutions. For each class of primitive, a brief description of the purpose of the primitive is provided, with notes on its co-ordinate origin, default size and rules for scaling. A list of the available primitives is shown.

AxesAn understanding of the orientation of the co-ordinate axes is essential for authoring a part for LDraw. For reference within this page the axes and their direction is shown in this diagram.


Rectilinear primitives

Nomenclature

Boxes are named boxF, with F representing the number of faces a box has. The suffix E represents the number of edges removed.

F and E are may followed by an additional letter. The hyphen is removed if F is accompanied by a modifier.

Face modifiers:

  • o - faces are opposite to each other
  • t - faces are all touching each other (usually, it's implied, but box4t.dat is a thing)
  • u - missing faces form a U-shape

Edge letters:

  • p - groups of edges are parallel to each other
  • a - some missing faces have no adjacent edges

Scaling and orientation

These rectilinear elements may be scaled in the {x}, {y} and {z} dimensions to make elements of any size. For example

1 16    0 0 0    40 0 0    0 1 0    0 0 20    rect.dat

would generate a 80LDu x 40LDu rectangle in the {x,z} plane.

Although the default orientation of the rect.dat primitive is in the {x,z} plane the LDraw language allows for this to be transformed

1 16    0 0 0    0 1 0    40 0 0    0 0 20    rect.dat

would generate a 80LDu x 40LDu rectangle in the {y,z} plane.

1 16    0 0 0    40 0 0    0 0 20    0 1 0    rect.dat

would generate a 80LDu x 40LDu rectangle in the {x,y} plane.

Do NOT rotate rect primitives outside of right angles: 90°, 180 ... on all axes.

Curved primitives

LDraw represents curved surfaces as polygons. For circular components two series of primitives are provided.

All the circular primitives are orientated in the {x,z} plane with their origin at the centre of the circle and a default radius of 1 LDu. Primitives are provided for complete circles and for commonly used fractions of a complete circle. Where the naming convention includes a prefix of the form n-f this indicates the fraction (n/f) of the circle drawn by the primitive. Where this fraction is less than an entire circle, the primitive starts at {+x,0} and progresses in a conterclockwise direction when viewed from above {-y}.

To avoid rounding errors, it is preferable to use existing fractional circular primitives, or create a new primitive, rather than rotate an existing primitive by anything other than 90 or 180 degrees. For example, use 3-16XXXX.dat rather than combining 1-8XXXX.dat with 1-16XXXX.dat rotated by 22.5 degreees.

To avoid matrix arithmetic problems in some renderers, the third dimension ({y} in the default orientation) of two-dimensional primitives must be given a non-zero scaling factor. LDraw circles are normally formed of 16-sided polygons (hexdecagons) - the regular resolution. For larger elements, where scaling-up of hexadecagons would give too angular an appearance, a series of high resolution primitives based on a 48-sided polygon are available. These may also be used for parts not well suited to a 16-fold symmetry.

These circular elements may be scaled by the same factor in both the {x} and {z} dimensions to make circular elements of greater or less than 1LDu radius. For example

1 16    0 0 0    3 0 0    0 1 0    0 0 3    4-4edge.dat

would generate a circle in the {x,z} plane with a radius of 3LDu.

They may also be scaled asymmetrically in the x and z dimension to make ellipses.

Although the default orientation is in the {x,z} plane the LDraw language allows for these to be transformed

1 16    0 0 0    0 1 0    3 0 0    0 0 3    4-4edge.dat    would generate a circle in the {y,z} plane

1 16    0 0 0    3 0 0    0 0 3    0 1 0    4-4edge.dat    would generate a circle in the {x,y} plane

Regular resolution (n-f): 1-16, 1-8, 3-16, 1-4
Low resolution (n-f): 3-16, 3-8

n-ftndis.dat Disc negative truncated
1-8tndis
Tndis-example

This suite of primitives are used to used to integrate circular elements into rectilinear elements. These pad their matching n-fdisc.dat primitives out to the bounding rectangle, spanning from x = 1 to the minimal x value of the matching primitive. Note that the bounding circle in the image is for context only - only the black segment is generated by the 1-8tndis primitive. The image on the right showes the difference between tang, tndis and ndis.

Currently available primitives:
Regular resolution (n-f): 1-16, 1-8, 3-16
High resolution (n-f): 5-48, 1-24, 1-16, 1-8

n-faring.dat Circular adaptor ring segment
2-4aring This suite of primitives are used to interface between high resolution (48-segment) circular primitives and normal resolution (16-segment) circluar primitives. Note that the bounding circle in the image is for context only - only the black segment is generated by the 2-4aring primitive.

Currently available primitives:
High resolution (n-f): 1-8, 1-4, 3-16, 2-4, 4-4

1-16chrd.dat
1-48chrd.dat
n-fering.dat		 Primitive Substitution Adapters
4-4edge This suite of primitives are used correct for gaps that form between curved primitives and normal geometry in editors that utilize primitive substitution. This is a special case used on the inside of a curved primitive where it joins geometry that cannot make use of a curved primitive. The chrd files themselves are simply a reference to empty.dat, which under normal circumstances does not draw anything. However, in tools that support primitive substitution, the curved primitive it is attached to would normally in this case create a gap when rendered using more than 16 points to form a circle. In that case, the substituted version of these normally empty primitives would fill in the gap between the curve and the other geometry.

To "see" these primitives, the editor in use must utilize primitive substitution. Then one of the following can be done:

  • set the curve quality to a level high enough to see the gaps reappear
  • For LDView 4.4 or later, in the Model Tree dialog, you can search for them (for example, "ering"), and if you have it set to highlight, then when you select one, it will be highlighted in the 3D view.
  • Manually recolor the primitive in question to a color that contrasts with the colors that surround it

Note that the bounding circle in the image is for context only - there are no actual geometry producing lines contained in these files.

Currently available primitives:
Regular resolution (n-f): 1-16chrd, 1-4ering, 1-8ering, 3-16ering, 2-4ering, 4-4ering
High resolution (n-f): 1-48chrd

ringr.dat (deprecated name)
ringrr.dat (deprecated name)		 Circular ring segment
1-4ring1 This suite of primitives are used to generate circular rings or part rings. The numeric suffix r in the filename indicates the inner radius of the ring - the outer radius is 1LDu greater. For example a n-f4-4ring4 primitive would create a ring with an inner radius of 4LDu and an outer radius of 5LDu.

Note: The correct nomenclature is to use the full word "ring". All newly created ring primitives must use "ring". Official files using "rin" have been obsoleted. All files using "ri" or "rin" have been moved, to use "ring".

4-4cyli This suite of primitives are used to generate cylinders or part cylinders. These are provided in two forms - with conditional lines (n-fcyli) or without conditional lines (n-fcyli2). In almost all circumstances the "cyli" version should be used. The "cyli2" versions are for very special cases and their use for the rounded corners of stickers is no longer appropriate.

n-fcyls2.dat		 Circular cylinder truncated by an angled plane
2-4cyls

3-8cyls

These primitives are used to generate cylinders or part cylinders which are truncated by a plane which is not perpendicular to the axis of the cylinder. The default angle of the plane is 45 degress.

These primitives are notoriously difficult to describe and the user is encouraged to experiment in order to gain a full understanding of their geometry. One technique is to open the primitive in LDPE and choose random colours. Selecting Show Axes also helps.

The 2-4cyls.dat primitive is orientated with the perpendicular bounding plane at the top {-y} and the angled bounding plane at the bottom {+y}. In common with the other 2-4xxxx.dat primitives, the {+z} semicircle is represented. By default the truncation plane is y=x-1. The 1-4cyls.dat and 3-8cyls.dat primitives are sub-sections of 2-4cyls.dat

The 1-4cyls2.dat primitive is orientated with the perpendicular bounding plane at the top {-y} and the angled bounding plane at the bottom {+y}. Unlike the other 1-4xxxx.dat primitives, the {-x,+z} quadrant is represented. The truncation plane is y=x.

The following observations may help :

1-4cyls and 1-4cyls2 are complements. If you put them together correctly they make a 1-4cyli.

n-fconr.dat
n-fconrr.dat		 Circular cone
4-4con1 This suite of primitives are used to generate circular cones or part cones. The numeric suffix r in the filename indicates the inner radius of the cone - the outer radius is 1LDu greater. By default the cone is 1LDu high in the {+y} dimension with the origin at the centre of the outer diameter. For example a n-fcone4 primitive would create a cone with an inner radius of 4LDu and an outer radius of 5LDu.

T02i2000.png

T02o2000.png T02q1765.png

This suite of primitives are used to generate circular torus sections. By default all these primitives produce a torus with a major radius of 1LDu, so typically need to be scaled up in the {x} and {z} dimensions. The first character denotes whether the minor radius is smaller than (tff primitives) or larger than the major radius (rff primitives). The latter are termed reverse ratio tori. The second and third characters of the filename ff denotes the sweep of torus, as an inverse fraction (01=1/1, 02=1/2, 04=1/4, 08=1/8, 16=1/16, 32=1/32, 48=1/48). The fourth character denotes the section of a torus (i=inner, o=outer, q=tube - the combination of 2 inner and 2 outer sections). Inner sections are not possible for reverse ratio tori.

For regular tori, the last four characters of the file name rrrr denote the torus minor radius in LDu (1333=0.1333, 3333=0.3333), with the special designation 'unit' unsed to indicate a radius of 1.0000. For reverse ratio tori named like rfforrrr.dat, the last four characters of the file name rrrr represent torus minor radius with an implied decimal point after the first digit (1500=1.5, 4600=4.6). For reverse ratio tori named like rfforrrrr.dat, the last five characters of the file name rrrrr represent torus minor radius with an implied decimal point after the first two digits (11000=11.0).

These diagrams (based on an idea of Paul Easter's) illustrate the relationship of the torus primitives to the major and minor radii.

Stud primitives

Each studxxx primitive described below has a matching low resolution stu2xxx primitive, used by the fast-draw mode of renderers - these stu2xxx primitive must never be used in part files. An additional primitive (studline.dat) is used to substitute a single line for studs by the super fast-draw mode of LDraw.

All stud primitives are modelled with the solid disc uppermost, even if designed for the underside of parts (stud3, stud4, stud8, stud11). The origin is at the base of the stud and they extend for 4LDU in the {-y} dimension. To use for the underside, the primitives need to be inverted in the {y} dimension, viz.

1 16    x y z    1 0 0    0 -1 0    0 0 1    stud3.dat

These primitives must not be scaled in the {x} or {z} dimensions. Ideally they should not be scaled in the {y} dimension either, to allow the accurate substitution of chamfered studs by high-quality renderers [but this rule is flouted in the regular brick files, where stud4 is scaled by 5 to generate the underside tube].

Stud3 For use on the underside of parts (usually plates) between the gaps for studs. This is modelled with the solid disc uppermost. To use for the underside of plates, it is necessary to invert in the {y} dimension, like

In real life, more recent parts use a hollow version of this underside stud. Since this serves no functional purpose and many parts exist with both varients, this feature is not modelled in LDraw parts and the solid version is always used.

Stud group primitives

Stud groups are provided to reduce the size of part files with many regularly spaced studs. The naming convention is stugN-XxZ.dat, where:

  • N = type of stud (regular stud, hollow stud, underside stud, etc.)
  • X = number of studs on the x axis
  • Z = number of studs on the z axis

To prevent an overload of the library with excessive combinations, the numbers on the x and z axis are limited to:

  • 1xZ stugs
  • Xx1 stugs (Due to stud orientation you cannot rotate a 1xZ stud group by 90 degrees to get a Xx1 stud group)
  • XxZ stugs where X = Z

These primitives must not be scaled.
