@ triplus :
I already tried every approach...with always blocking points. :/
1. First I have problems with setting the 2D view the way I want, it comes on the YX plane, and setting up the position and angle doesn't work.
EDIT, I just made it, amazing!! I clicked on the ... on position in Data and I was then able to implement rotations one by one, the way I wanted!!
Using the draft workbench is OK, but I encounter strange behaviours with diameters, why is that?
I don't want to spend most of my time setting all the dimension lines that they can look like they should...
2. For the views, it's what looks the closest to my needs, but I was not able to install this add-on.
I read the topic, but even following step by step doesn't help. I am a bit confused about renaming and if it works (it seems I get error message at FreeCAD start).
@ jmaustpc :
Is it then better to use this dimension tool on the 3D object or on the 2D projection just created (with shape2Dview)?
A big thank you for your interest and help!
