I want to draw some props on the Rhino model via the DisplayPipeline, which include arrows but also other shapes. The current state can be seen in the picture below:
Drawing the props in the correct scale for the model is not a trivial issue. I am aware that the DrawArrow and DrawArrowHead methods can be used with screen size values that make sure that the props always look the same size no matter the model scale or zoom. This would be an acceptable solution for me.
However, as I also want to draw other shapes besides arrows, I was wondering if Rhino provides any methods to transform the other shapes to screen size as well.
