LeoCAD is a software application designed for computer-aided design that specifically utilizes plastic bricks in its interface.
LeoCAD is a CAD program that utilizes building bricks that are similar to the ones found in toys, but they do not represent any particular brand. The project has a library of more than 1000 different pieces, with most of them created by James Jessiman, the author of LDraw.
The installation process of LeoCAD is relatively simple. After checking that an OpenGL library is installed, users must download and extract the executable and pieces library to a directory of their choice. If a directory other than "/usr/local/share/leocad/" is chosen, users must set the variable LEOCAD_LIB to that directory. Users also have the option to compile the program themselves using the cvs server.
LeoCAD's keyframing feature allows each object in a project to have a different position and orientation for each step or frame in which it appears. This feature makes creating instructions and animations simple and useful. In instruction mode, each time unit is called a step, while in animation mode, each time unit is called a frame.
When creating animations, LeoCAD automatically interpolates the value of the previous and next key to calculate the position of an object at each frame. Users can add a new key at the current step/frame by depressing the Key Button on the Animation Toolbar. The changes made when the Key Button is not pressed affect the key immediately before the current step/frame.
LeoCAD is a powerful editor that enables users to create building instructions and animations with ease. Switching between modes is simple, and the position of an object in one mode does not affect its position in the other mode. To copy the position from one mode to another, users can choose "Copy Keys From..." from the Pieces Menu. Overall, LeoCAD is a great software for both beginners and advanced users looking to create brick-based models.
