How do I slice 3D objects made by Thickness Property? 1

[Ammo]

I have created a channel in AutoCAD 2000, by creating the cross-section and applying a thickness to the lines. Then I changed view to the yz-plane. I tried to chamfer the corners off the side of the channel by a multitude of methods, but was unsuccessful. The main comment I got was 'no object selected'. What am I doing wrong?

You have made a surface. You need to make a solid. To make a solid, draw an enclosed area and turn it into a region. Then extrude the region.
