Using ST7.... Is there a way to type the formula you want for a dimension in the little box that show up when you add or click on the dimension when in a sketch profile? Instead of having to double click and then enter the formula?
No, I'm afraid the UI is set up to only allow for value and units in the input box.
You either have to double click the dimension to get the formula input box or use the Variable Table. FYI: With dual screens, I keep the Variable table up on my second screen.
If you are just adding, subtracting, dividing, multiplying, etc. a constant number, you can single click on the dimension to bring up the value change box. Then delete the units, then do whatever operation (with a number) you want. However, if you need it related to variable, then you have to double click as already mentioned.
