Hi Peer,

Yes

>I can imagine that adding the icon might not work, but if you set up a shortcut key for "Ordinate" does that work?
I did this and it works. Thanks

I noticed that it is therefore necessary, to carry out the dimensioning, to move the supposed (chosen) origin of the coordinates of the element that we want to dimension (the local 0.0) to the origin of the world (the 0.0 overall).
In the example case of my plan above, I have 3 local origins. So, 2 movements of all the elements (entities) created.
