...Every post has a heading that is a copy of the topic title...

I was looking for some key/button at the top of the post...
The only ones I could see were "report this post" and "reply with quote"

the macro work by 2 point clicked and display the info
measure linear - from datum, origin?
more explanation (or photo example)

Maybe you need a special feature, go into Macros_recipes and Code_snippets, Topological_data_scripting, Dialog creation. My macros on Gist.github.

sorry, didn't explain myself well enough :oops:
What I meant, was that I had two known dimensions.
Z was measuring OK (green circled)
X was leaving me in doubt (red circled)

X should have measured 34.2 (same like Z was measuring 22.5)
instead it was telling me 34.20000076293945
Why?

Plus, you have to remember to turn macro off after doing measurement ;)
I had some strange behaviours when I didn't do it
Macro was trying to measure things while I was doing something else :mrgreen:
My personal preference would be for the macro to be "one shot" and "off"
and fire again when needed again, but this is not a biggie ;)

In this example I was looking to find a distance between selected model face and XY plane of origin.
This of course only makes sense when both planes are parallel.

Just a quick note, Mario is very intelligent and does some amazing things, but he is French and has very little understanding of English, so be patient. :)

Oh, I wasn't rushing, just explaining that I am bit slow :mrgreen:
Full respect to Mario and I am very grateful for all the help I am getting here (in particular from Mario).

Your English is better than my FreeCAD :lol:
If I have difficulty understanding something,
it is not because of your English,
but because of my lack of knowledge of FreeCAD, Python etc...
