Hi Trevor, thanks for the macro. It does crop the image to the frame with ease. The issues that I see with the macro are that I cannot go back to 3D, and it moves the cropped image off the layer it was imported to and places it on the illustration number layer.
Another method we have used is to duplicate the frame, then create another box over the hatched box that encompasses all the model that is outside the hatch pattern. Select both boxes and create a compound path, then place a fill on the new compound box and then remove the covered elements. This maintains the ability to go back to 3D and keeps imported models on there respective layers.
Thanks
Bryon
