tl;dr: I am creating/baking angular dimensions from Python, but negative angles never show a minus sign. How can I change the Dimension style to respect the sign? Or alternatively, how do I parse the result of ghpythonlib.components.AngularDimension(…) so I can bake it?
I need to create/bake angular dimensions from Python code. I see 2 ways to do it:
Use Rhino directly, like this: How to make Angular dimension by Python Rhino
Use ghpythonlib.components to call the Grasshopper AngularDimension component directly.
I’ve gotten (1) to work correctly EXCEPT that the baked dimension never has a minus sign when I think it should: I’m passing in positive or negative numbers for the angle, as appropriate for different cases, but the dimension always shows as positive. For instance, here is my baked dimension (black) and a preview of the dimension produced by the Grasshopper component (red). the angle is specified at -144.9:
(Note I’m always referencing off the x axis, and I want clockwise positive and ccw negative.)
I would actually love to use (2), calling the component directly from Python with ghpythonlib.components, but I can’t for the life of me figure out how to parse the result. This code:
import ghpythonlib.components as ghcomp res = ghcomp.AngularDimension(C,A,B,False,T,S) print(res)
gives me this:
But the array is zero length, and what do the nested parens mean?
In summary, I either need to figure out how to make the dimension style respect the sign of the angle I give it OR figure out how to parse the result of ghpythonlib.components.AngularDimension(…) so I can bake it.
Any help or insight deeply appreciated.
