I thought about it, but should take another look at it, that scripting extension looks like a good way to get in touch with it. When I had a look at it, I was under the impression, that you can't get immediate enough to the core functions, for an extension to make sense. You are just drawing too many lines to make going through a pop-up every time feasible. You want to specify exact lengths while drawing, not afterwards. In Vectoworks e.g. line drawing works like this: click on the starting point/node, choose the angle by moving your mouse, enter length (length field is always pre-selected), press enter. Optionally press tab to enter a more precise angle if it's not dividable by 15, but you probably have an alignment point selected already, so you don't need to put the angle or even the length. You do this 100 times in a row. And if you edit a shape, the measurement input is always immediately accessible aswell. Adding a text and visual measurements is something you do when the drawing is complete and you manually lay them out, because you want to choose which measurements to include and you lay them out in a nice line so other people can easily comprehend what you want to communicate with you drawing. Sometimes you have the same drawing with different measurements, because you are communicating a different aspect of the drawing.
