It is useful to overextrude a Shape so that you have better access to the internal edges to do a vertical chamfer. Ss1 the block is 9 in high but say I really want it to be 1 in high. I want to Extrude the top face -8. Ss2 The Extrude tool proposes 5 but I change to -8.
The shape stays the same height but you can see a new line 1 in from the bottom that results from my -8 extrude. (1 in verified by added vertical line)
It seems that you can successively Extrude up but not down.
Is this normal? If so, how to eliminate top 8 in of shape?
I was able to work around this by pushing the top down 8 in but I would expect the Extrude tool to work similarly?
Please comment and thanks for looking at this.
