As I am drawing an object and establishing dimensions, unless I use the dimension command to hold those physical dimensions andmake changes to the object, those dimensions that I have not specified are likely to change. Two questions:
1. Is it necessary to place all dimensions on a drawing as it is being sketched in order to hold the dimensions in place?
2. If number 1 is not the case, why are my drawings changing size as I make changes to other areas?
I expect I just don't fully understand the workings of this software, (it is certainly different than AutoCad), but I would really appreciate any help that you can provide.
