Hi V5 Aligned dim fails to put a dimension centre to centre on these ‘markers’ when placed in perspective view. If I do so in ortho view the dim does not travel from marker to marker. Bott left to middle right I hope is 54 inches measured on site on the front face. for example but I am unable to…

DimAligned works on the Cplane, so set Cplane accordingly for each dimension placed in the Perspective View. [image] [image]

Hi, Thats v bad news for me, as :- Thats a lot of separate C plane creations, is there no way to do this any other way as I am trying to place these markers in 3D space given the constraints of the dims to a certain marker from its nearest neighbours, and from each of those to others and the buttr…

If you don’t have a surface to attach the CPlane to, you could draw construction lines between the markers and set CPlane to Object

A fundamental rule in Rhino is all dimension annotations are created coplanar to the CPlane in the current Viewport. An old drafting rule was a dimension should never be drawn that can not be checked with a scale.

You don’t even need to draw a line. Set x axis to the points with 1 click to start the command and the 2 clicks to set the axis. No line to delete or clutter your model. [set cplane by x axis] The question is not if “Rhino knows” the distance, but how you want the measurement to be made. I think…

[image] Steve1: Bott left to middle right I hope is 54 inches It is 52.1" on your model… Thanks to @BrianM and @abrahamwechter - I didn’t know you could set the cplane like this and have the dimension “stick” after changing it back. But as @John_Brock says, dimensions should be in the drawin…

[image] John_Brock: a dimension should never be drawn that can be checked with a scale typo: can = cannot! (The other rule - written on each drawing but oft ignored - was “Do not scale from this drawing”…)

I made this script a while back, maybe it’s useful for you: #! python3 def mark_distance(): """ script written by Gijs de Zwart draws a line with arrows and dot annotation with the distance between the two picked points """ import Rhino import rhinoscriptsyntax as rs …

Do you mind to remind me how to use this script? :slight_smile: I tried to compile it, but failed.

How can I place a diagonal dimension between these markers in 3D and not Ortho?

Fixed! Thank you!
