How to change dimension of a extruded object
Read 208 times

Hi,
I have a 3d object which is created by simple extrude tool. Now I have to widen its upper part without changing its base dimensions, as on attached pic.
What should I use in order to do that? I've tried editing the extruded object, but I can only resize it affecting all the measures.

One way is to apply Slice by Surface, using a pair of extruded arcs as the slicing surfaces.

Thanks. What I did:
- revolved object with those 2 arcs creating sphere-alike object,
- used 3d slice to cut it according to specified dimensions

Only problem with it is that the upper part is not flat.

EDIT
This is still not the best solution.

The right solution is to extrude object (not to revolve it, because of the flat lines needed as an end result), and then to cut it with 3d slice.

"The right solution is to extrude object (not to revolve it, because of the flat lines needed as an end result), and then to cut it with 3d slice."

That is probably the best approach if you're satisfied with flat slicing planes. Slice by Surface allows non-flat slicing "planes."

Very useful indeed. Thanks again.
