Let's say I have "the letter I" shaped object extruded one inch. I would like to cut some of the middle to make the length a little smaller, but do not want to half to cut all the way and cut some of the lower part of "the letter I". Is it possible to make that cut, but then merge the top and bottom without having a gap there? Basically I want to know if it's possible to make a cut, and then merge the two sites together.
yes, it is possible to do that. though it is usually easier to just edit the original I sketch to the size you need. but here is how to do it this way.
1) make the cut removing the material in the middle.
2) use the "move/copy bodies" feature to move one part to the other.
3) use the "combine" feature to make them one body again.
