This question came up on another Forum so I checked the whole thing and here is what I have found:
I feel we have lost functionality in AC17, which could and should be restored.
Up till AC16, with the Dimension Tool active, using SHIFT-click you selected a Dimension Point the Witness Line of which you wanted to adjust. Then, without moving the cursor anywhere, you could again click on the Dimension Point itself to start defining the new length of the Witness Line. ArchiCAD knew that if you select just one Dimension Point and click it again you want to adjust its Witness Line length.
So it offered a very fast way of adjusting a single Witness Line and it worked pretty fast. (Of course, when you select two or more Dimension Points to adjust with SHIFT-click this does not apply.)
However, since AC17 this does not work anymore when you click the Dimension Point after SHIFT-clicking it. Now you have to move your cursor to some other portion of the Dimension Line where the cursor senses only the Dimension Line (Mercedes cursor) and click there for the Pet Palette to appear so you can select the proper Pet Palette command and start adjusting its Witness Line Length. In AC16 ArchiCAD assumed that if you click on the Dimension Point after selecting it you want to adjust its Witness Line so it automatically used that command of the Pet Palette (the Pet Palette did not even appear).
I think this functionality should be restored so that we can adjust the length of individual Witness Lines very swiftly like we used to be able to do.
What do you guys think?
