We have a cam lobe that our supplier measures in spec, but when we try to measure the same profile from what's supposedly a nominal cad model it's out of spec. We have a similar part that has the same issue that we sent to Hexagon and was measured using Quindos that was found in spec and the result correlated to the suppliers. The profile of lobe is defined by a tabular data file that looks like this:
We're wondering how to import this data into the demon.
One thing to think about: in the data it says "lift". That would indicate a measuring device like a dial gauge that is always perpendicular to the rotation center of the part. So, no need to calculate vectors, cause the vector will always be something like 0, 0, 1. On such a small part, calculating a compensation vector perpendicular to the profile might give a wrong impression of the true deviations.
