Some time ago, I posted two alternative ways to build 3d dimensions in Rhino, even though they were not exactly what a true native 3d dimension should be capable of. I will try to find them now.
Thanks for sharing those! I slightly modified your 4th macro to turn the camera at 180 degrees instead of 90 degrees, because this is handy when modeling cars.
Reverse camera view
-RotateView a 180 l, -RotateView a 180 r
This is a macro that I created to overcome one weakness of Rhino’s default ! _Line _Tangent _Pause command. It will ask for a planar object to temporarily align the CPlane to it during the command, then it will revert to the previous CPlane.
Line: Tangent and perpendic…
Two macros for creating of a vertical dimension or aligned dimension directly in the Perspective viewport:
This video shows how to use the 3d dimensions:
A proposal from 2019:
The easiest way would be to use 3d dimension, that, at the moment, is not yet implemented in Rhino 6, but hopefully will be included in Rhino 7 (or a future update of Rhino 6). I imagine it could work this way:
Pick the start point for the desired distance.
Pick the end point.
Snap to some object that closely matches the plane at which you want the dimension to be aligned. It should work exactly like the last click of the “Rotate 3d” command where you pick the angle of rotation while the start…
Another important thing to consider:
Great idea, always wanted this. Easily voting for this to be implemented. However, I would love to see a slightly different version of the angle dimension, featuring a customizable length of the straight extension tangent to the arc, with the angle numbers following the same orientation perpendicular to the extension (optionally, also horizontal or vertical). That would be extremely useful, especially for small dimensions:

Also, I find the default dimensi…
