I often need to position Layout drawing objects to the mid-point between two points and I have previously drawn a line between the two points and then moved the object to snap to the line midpoint.
I’ve just discovered a less clunky way ( in my opinion ) – I snap my object first to one point, then snap to the other point and then type 2/ – then delete the other instances of the object.
I knew about this but it always seemed like more steps. I usually just draw a line (as a snapping reference) and move the object to the midpoint then delete the line.
I get that, but in this particular case, inferencing the midpoint of the door jamb is easier than the copy - /2 - erase method (IMHO). Everyone has to find what works best for them.
