I would like to make a 1" long, 1" diameter straight pipe as a block. I would like to insert that block into my drawing, say...on a 90 degree elbow. After inserting the straight stub, I would like to use a grip to "stretch" the pipe length to the next fitting. Ultimately, I would like to compile a parts list for my pipe drawing that will give me the straight pipe length. I've been doing some searching and 3d dynamic blocks seem to be impossible.
Thank you in advance for your support and cooperation.
It is not possible because 3d solids can not be stretchable. Scale works but in your case it changes your diameter to I think you do not want that.
I offer a different solution with basic line and circles. Attached block works as a pipe as well take look.
