Create Section Cut (Tip #2191) by Raymond Rizkallah works with 3D models in AutoCAD to create a hatched-section detail that resides on the same layer (and color) as the original model. Draw a 3D model using cones, boxes and so forth in AutoCAD and then load the LISP code for this tip. Type SEC1 or SEC2 to start the command. SEC1 keeps the hatch on the same layer/color as the original and SEC2 doesn't update the hatch color. Select a LINE object that defines the cut (as viewed down the UCS), and the routine creates the section and then waits for you to place it in the drawing. The section cut program does a lot of work, so it may require a few seconds to accomplish the task based on the complexity of your model. Nice programming!
