I have a noob question, but I just can't figure it out.
I've created ordinate dimensions using horizontal and vertical ordinate tool in drawing mode. The first click sets zero and I pick a few dimensions to add ordinate dimensions based on that zero. Now, I have added features after the fact and need to add more ordinate dimensions using the existing baseline, but when I click on the tools it wants to make a new zero point.
How do I add new ordinate dimensions to an existing baseline?
