Rhino small angle detection for mold

hello!

I need to create a mold for my carbonfibre monocoque car but the expert says that there is a very small angle that prevent us from creating the mold. is there a way or a command that can help me detect and find this little angle?

Under the Analysis menu, there is Draft angle analysis. You can set the max and min angles and the direction to try and find the problem spot(s) visually by color.
