My client milled a large object (yacht deck) with their 5-axis machine to find out that one surface has an unpredictable shape. When they imported the surface it was correct as I have the original design file over here.
We will probably never know what happened in between, but what is wrong with this surface?
As you maybe can see, there’s an unexpected ledge at the top edge which is weird when I look at the control point distribution. After _ShrinkTrimmedSrf, the shape is correct again.
I’d like to know what is happening here.
Thank you in advance for taking a look.
