Hi all,
I have a shape that I want to extrude into a solid and then I want to insert a series of surfaces into the solid to extract the middle part. I have included a drawing that may make this more understandable. On the left is the solid created from extruding the outline. On the right is the internal surfaces that I would like to use to create a hole in the solid with the internal edges defined by those surfaces. I can't just extrude an external and internal outline because the internal surfaces have some angles in them.

I've tried to use the Merge command but I couldn't get it to work the way I needed. Then, just for the halibut, I tried the Trim command, but it didn't work either. Can anyone tell me how to create that hole with the slanted sides in the middle of the larger solid?
Thanks,
Mark
