Hello,
We have designed a (roughly hemispherical) moulding and had it made.
The manufacturer has had a third party measure the resulting component and
has produced an IGS file from the measurements.
We would like to compare the two sets of surface data (as designed and as
measured) and find the differences between the two, and to be able to show
the size and position of these differences on screen.
The differences should be based on a 'best fit' of the measured data to the
design data, since we do not have any well-defined datum features to locate
one set of data to the other.
Is there a way to achieve this analysis in Pro/E, and. if so, how is it best
done? If Pro/E cannot give us the answers we want, is there an alternative
approach?
We think we have figured out a way to do it if we can assume the
manufactured component is located in space using a coordinate system, but,
in practice, we have no such coordinate system.
Measuring the component again is not an option.
