Please help!!! I created a gear that I need to extude to 1 inch. After I created the object and did all the trimming it will not join as one object using the join command or become a region. It will join together as a block. But the block will not extrude with the extrude command, thicken command etc. I attached a DWG copy. Thank you so much in advanceuploads/481025/sprocket_problem.dwg

ok well I used presspull command to get the extrusion. So it looks like a solid object. However it is not and I need to cut out a smaller circumference from the middle for were the axle will slide through. Thanks again
