Reverse Engineering or Playing too Much Big Toys?

[[Mi...]]

Helping out a buddy at work. Project is building a luggage rack for his trike. Was asked to measure his manually reverse engineered pressed wood model so we can make a 3D print model before cutting metal. Doing reasonably well in measuring. Got a big surprise when Calypso followed exact contour of large odd shaped plane. Maybe because I am measuring single points? My main question is about the stylus missing the target when attempt measuring narrow ( 3/16) plane for Y origin. It seemed to have worked 1rst time through but now it just slides across Z-surface and errors out.
Is it too much waste of time to measure this type of material?

Hard to tell without seeing the part itself. If I understand the issue right...

If you have a point feature defining the Y origin, try defining its Z nominal based on the "odd shaped plane". Open the point's feature editor, right-click the Z box, select "formula". Recall the "odd shaped plane" actual minus, say, 3/32". When you run it'll measure the plane first, then move down from there 3/32" to get the Y origin.

Or it might be something completely different.
