CAD: Computer Aided Design

All of the modern era kits sold by Lyforms Small-Scale are designed in a CAD program on a computer. CAD stands for Computer Aided Design. It allows you to create a 3D model of an object on a computer through the assembly and destruction of basic shapes. Complex shapes are created by intersecting basic shapes and then adding or subtracting them from each other.

Say for example that you'd like to create an "L" shape. There are two ways that this can be done:

  1. Create two rectangular boxes that are perpendicular to each other and join them together at their ends.
  2. Create large box shape followed by a smaller one. Intersect the smaller box with the larger one in the upper right corner and then subtract the smaller one.

Some CAD tools will allow you to draw a shape in two dimensions on a flat grid and then "extrude" the shape from the two dimensional version into 3 dimensions.

Other things can be done to shapes to further their appearance, such as rounding off edges and corners or beveling them.

3D models can also be viewed from all angles in the CAD program so that you can see approximately what the object will look like before being printed on the 3D printer. This can come in handy when you want to see what an object will look like before it is printed.

Using CAD tools can ease the process of creating Lyforms Small-Scale modern era kits by viewing design mistakes before they get to the 3D printer. Any tweaks that are needed after a print can be done quickly in the CAD tool and saved under a different file name until the design has been perfected.
