3D Profiling, Z Plunges in the Corners

[alex_holden]

Hi, I've just been experimenting for the first time with the 3D profiling operation. I created a sloping flat rectangular surface from the attached text file and used a horizontal 3D profile operation to taper the top face of my part. It worked great! Just one odd thing - why is it doing several full depth Z plunges in the top left and top right corners, and is there a way to prevent it?

I'm using version 0.9.8P.

See attached cb file.

1. Made a new layer called "Boundary"
2. created a rectangle the same size as the stock (polyrectangle1)
3. in the 3DSurface1 MOp set "Boundary Method" to "Selected Shapes"
4. in the 3DSurface1 MOp set "Boundary Shape IDs" to 1 (i.e. polyrectangle1)

To adjust how the tool cuts within the boundary shape, play with values in "Boundary Margin" it can accept both positive and negative numbers.
