Here is a tip from someone that offered an answer to Solid Digital Digest. The question asked was about how to move sketch entities to a particular location. The 2D to 3D tool bar does a good job of letting you pick a point and then putting that point at the origin. But this tip offers something else.
"Another method is to edit the sketch, window select all the sketch entities to move, hold down the control key and drag a vertex - and while dragging, release the control key. Drop the vertex on the origin of another vertex in the model."
It doesn't even have to be a vertex you go to, it can also be a midpoint, etc. Good one to know - thanks to whomever.
