Ok… This is a Newb question, that I hope is something stupid that I am missing. How to I CHANGE something, after the fact?
A very simplified example:
I design very simple square “washer” like object. 1inch square, with a 1/4inch hole in the center. camphor some edges. Print it out, GREAT! But… a 1/8 inch hole would be better …
I can not figure out how to go into the drawing/model , and ONLY change the size of the hole! All i can do, is either keep hitting the “un-do” button, until I get to a point before i did any extrusions, or start from scratch.
Starting from scratch, for something as simple as what I described, is no big deal… but for larger, more complicated projects… not so much.
PLEASE, tell me I am missing something very basic?
