Do you like to create custom symbols for your user library? In X13, you can now do subtract, intersection, and merge between both polyline solids and 3D solids. These boolean edits can be performed in both a plan and elevation view. 3D solid shapes also now include elevation information to define the reference like absolute or finished floor for the top and bottom.
