Which part type
From LDraw.org Wiki
Sometimes it is not that easy to identify the part type to choose. Here some hints:
Currently the following part types are valid:
If parts placed in the \parts folder they have to be Parts.
- Part Alias
If a Part only is a reference to another Part file because the real part occurs with two numbers then it is a Part Alias.
- Part Physical_Colour
If a Part has complete fixed colors then it is a Part Physical_Colour. This is mainly introduced for interchangability with LDD.
If parts placed in the \p folder they have to be Primitives.
If parts placed in the \p\48 folder they have to be 48_Primitives.
Shortcuts are special parts. Normal parts are made from quads, triangle, lines and subparts and should be shown in a viewer application as a solid piece. If a part is made from other parts (glued together for example) then the viewer application should treat the content of the file like a model with visible gaps if the user whishes that. So if at minimum two Parts referenced to then it has to be a Shortcut.
- Shortcut Alias
explanation for Shortcut Alias to be added here.
- Shortcut Physical_Colour
explanation for Shortcut Physical_Colour to be added here.
If parts placed in the \s folder they have to be Subparts.
Better wording is always welcome.
