Can I post sketchup files (as links) for review.
For example, I'm drawing a fold up bench for the garage. Can I post the drawings as a question to get feedback on my design?
It depends. First you need to ask specific question(s) on the design, not 'have any opinions?' Which sometimes happens.
I'm not sure what our policy is on linking in the designs, since we want the questions to be mostly self-sufficient, and not have to worry about the links dying.
So I would recommend having at least one of the drawings embedded in the question, and link to the rest. The most useful one for the question.
And remember you can always ask multiple questions if you need.
