TechDraw ordinate dimensioning

Post by drmacro »

I did a search and there was mention of ordinate dimensioning a while back.

Was it ever on the radar in TechDraw?

Could it be on the radar?

This shows baseline linear dimensions not ordinate dimensions.

Ordinate dimensionin like this:

You set a 0-point and the next points are dimensioned against the 0-point. Used especially in drawings meant for lathe work.

SolidWorks has separate tools for that.

I created a GitHub ticket: https://github.com/FreeCAD/FreeCAD/issues/6587

This idea is really interesting, it would be nice to have such tools implemented in TechDraw. Here's an older thread where someone asked about it: https://forum.freecadweb.org/viewtopic.php?f=35&t=27008

Yes. Indeed. I was thinking the same a couple of days ago. But I'm glad it not just me. :D

In inventor you need to put a datum point, which the will become x0 y0 for that view. The you can crack on doing both horizontal and vertical ordinate dimensioning.

Its used more and more frequently in industry as well. :mrgreen:

So +1 from me as well.

This won't make it into v020. Probably v021.

@wandererfan I would like to contribute to the development of this function. I don't have any prior experience in FC dev. Where would you suggest to look at to get things rolling? A similar function etc?
