GD&T in Rhino

I’m making 2D drawing of some machine parts I want to have manufactured. It’s very important that a hole is perpendicular to a certain face, and that two faces are parallel. I therefore want to put those symbols in the 2D drawing of my part. I can’t find them anywhere in drafting section of Rhino. I looked online but could only find some people recommending certain fonts, which seems very unpractical and slow to use for larger/more complex machine parts.

Could someone tell me if GD&T (Geometric Dimensioning and Tolerancing) is in any way or shape possible in Rhino 7, either in the software itself or by use of plugins?

To be clear, I want to do something like this:

Hoi Lars -

If you change “in any way or shape” to “in a productive way”, I’d say the answer is no.
The feature request is on the list as RH-18620 and I’ve added this thread in a comment.

Perhaps you are referring to this thread?

Yes, rather unpractical for larger assemblies…

In Rhino 7, you can create attributed blocks so that you’d at least get asked for values and letters when inserting the block but you’d have to create all possible blocks first and also attach leaders after you’d place them…

Hi Wim,

Thanks for responding. That’s indeed the thread that I found. The attributed blocks seem rather unpractical as well.

Thank you for adding my thread to the request list. Any chances of this being added to Rhino 8 (or Rhino 7) in the near future? I see that the thread is 9 years old but I would like to use this in my workflow for drafting parts, as I work with a lot of parts that require form tolerances or they won’t fit.

Right now I need to switch from Rhino to either AutoCad or SolidWorks to add the form tolerances for bigger parts/assemblies, and for smaller parts I need to draw the shapes of the boxes manually and then use alt-codes to add some of the symbols. This works for now but if this feature is going to take another 9 years I’d need to look for a different solution :sweat_smile:

Again, thanks for responding!


Hoi Lars -

This will not be in Rhino 8, no.
As long as you have access to different CAD software and you need GD&T, it makes most sense to use that other software to create your drawings.
