CEB Press v16.09/SCAD Files/Parametric
Default Variables
By making a SCAD file with the variables used throughout the CEB press, we can use the "include" command within each individual part's file to pull in the same dimensions. Read More

Common Modules
Creating a file of modules will allow for them to be utilized in other files with the "use" command.
