Another 2D Curve Editing for Surface Profile Question

[[Mi...]]

Getting really good at removing what I thought were bad points from 2D Curves used for recalling points into Surface Profile. Maybe I'm over editing? Have part where am getting some Outiers at vertex(s) from flat surface to radial (concave) feature as in attached JPG. Still had a couple bad ones in 3rd and 4th 2D Curves. So, I removed another point either side of the vertex. As seen in the screenshot of CAD and Table Protocol, problem gets worse. The vertex at opposite side of the radial does not have the super bad outliers. All the other transitions from flat to radial (all convex) or flat to flat do OK. Am attaching JPG to see if any one has a good solution.
Also tried one of machinists' solution he claims worked at previous employer: Put a piece of paper at vertex. NOT! Calypso just measures the paper!

If you're scanning around corners with curves I would suggest not doing that. You're going to get all sorts of weird points because of the bounce of the probe and the inability of the machine to keep the same probing force as it scans. Plus, you have to slow the machine down so much and end up deleting/not evaluating some points that it's pretty useless, IMO.

I usually break my curves up to avoid this. I also start a curve on the flattest surface possible of the curve, even reordering points if necessary, and allow some run up distance to allow the probe to settle.

You can also choose not to evaluate some curve points, as opposed to hard deleting them. Not sure if any of this helps but just some info that might help.

Edited to add: Look at where the red/bad points are relative to the vertex. From your picture it appears you're scanning from right to left through that concave section. The corner points on the right are in the concave section because of the probe bounce and on the top on the other side because of the same thing.
