I'm talking about the standard measurements found in standard CAD software.
I know nothing of scripting or coding or whatever, but I can imagine that this is possible?
It could work similarly to how the "measure&contruction" function works currently, except implemented like in CAD software, making it possible to visually annotate measurements to scale.
If anyone thinks this will be a relatively easy thing to script, I'd be more than willing to fund some exploratory implementations.
Any ideas or comments welcome.
