Parts which fall under this agreement will contain the following line in their headers. 0 !LICENSE Redistributable under CCAL version 2.0 : see CAreadme.txt However this text is not a license! It is simply a handy reference for understanding the Legal Code (the full license), which can be found in the CAlicense.txt file — it is a human-readable expression of some key terms. Think of it as the user-friendly interface to the Legal Code beneath. This text itself has no legal value and its contents do not appear in the actual licence. For a deeper insight please visit: http://creativecommons.org/licenses/by/2.0/ 2. Rights You are free: * to copy, distribute, display, and use the CA approved LDraw Parts Library * to make derivative works * to make commercial use of the CA approved LDraw Parts Library Under the following conditions: 3. Attribution. You must give the original author credit. * For any reuse or distribution, you must make clear to others the licence terms of this library. * Any of these conditions can be waived if you get permission from the copyright holder. The LDraw Steering Committee (SteerCo) also holds an attribution to 'The LDraw Parts Library' in such Derivative Works to be sufficient in lieu of a full list of authors. Your fair use and other rights are in no way affected by the above. 4. Enforcements The single copyright holders are the sole entity responsible for enforcements of their copyrights. For purposes of enforcement LDraw.org considers the following good rules of thumb to determine if a new file is not a Derivative work. Anything else should be considered a Derivative work and an attribution would be required. If in doubt contact the current LDraw SteerCo. What is not considered a Derivative work? * Rendered images generated from the LDraw library. Rendering here covers any conversion of a 3D model file into a 2D image. * Model files containing references only (the source code for the part may NOT be included in any form) to parts in the official LDraw Parts Library at the time of their creation. Part files which are marked as unofficial at the time of creation may be included in full in the model file. If the sole or main purpose (as determined by the LDraw SteerCo in consultation with the potentially offending author and LDraw community at large) of the Model file is to include large numbers of unofficial parts then it WILL be considered a derivative work. * Alternative libraries of parts which LDraw.org does not own or enforce the copyright. If some or more of the parts in the library are converted from the LDraw Parts Library then they must be considered a Derivative work.
