This is probably the best solution

The workbench is written in c++ so it's not as easily accessible as if it was coded in Python. The image importer seems to use alpha-cannel for the displayed image but it's not exposed to the user-interface so you need to change the c++ code to enable setting semi-transparent images if I understands...

hi JAndersM I added the title in your macro to history, nice work Thanks! Very nice and useful. I have done a short movie to illustrate the workflow: Given the blueprint of a model create it again .. https://youtu.be/2iFE40uHrA8 :) Good video! Making the Image half transparent would be helpful ... ...

That might be a better description. What do you say piffpoof?

Fine! To be exact I think piffpoof means the parallax effect viewing objects at different distances if not close (at) the line of sight rather than the parallax due to different lines of sight. This makes scaling hard to do: You can reuse the image in the wiki if you want. (I drew it)

As parallax is the major problem with this method, perhaps the first sentence should not use the word "easy"? Dealing with parallax where there is any depth of field is certainly not easy. In fact I would suppose that overcoming it would require stereoscopic viewpoints with sufficient dis...

Looks good!

I have been looking for modules /functions (Python) to handle locale (like dot or comma in decimal numbers) and unit conversion from/to user preference to internal mm without much success. I have probably missed some obvious place. What do you use to handle these cases? For gui things I assume you u...

Ok, thanks

Here is a new version using DraftTracker to create a line between the measurement points.

I do not understand, sorry.
