This tool helps to check the draft angles of parts for castings and injection moldings. It significantly improves the workflow.  
You can check the angle from surfaces to a plane. Because it is a surface analysis tool, it could be located next to the zebra analysis. It marks faces with a certain angle with a certain color. For example, areas with a positive angle green. Surfaces with negative angle, red.

Because the angle is needed for manufacturing, and therefore is subject to various requirements, it should be an adjustable interface.

I second this feature, I’m using Sharpr3D to design investment cast parts, and needing to check I haven’t stuffed up any draft angles or undercuts with another software significantly slows down the workflow process.

This would be really helpful for designing parts to 3d print without supports as well.
