Measurement points "moving"

I specified a point on the surface of a radius in the modeling part of Creo along with references to planes to give the point an exact position in space while being specified on a surface first.

I then created a structural measure linked to this point.  The analysis model was run and when looking at the results, I went into info/measure and created an annotation for the measure at the predefined point.  However, the position where the measure was taken was not in the correct position.  In fact it was on the edge of the radius instead of approximately in the middle.

Does anyone have any ideas why?

I got with PTC support and the problem was the accuracy setting for the geometry.  The absolute value was only 1/3 of my radius size.   Reducing this by a factor of 4 fixed the problem.   Lesson is that a small feature needs to look accurate on screen to pick up a point for measures.

No the measure was not on a deformed plot. 

The measure points moved to the edge of the radius closest to the point specified.   I have now created points in the simulation module, attached measures and am running a model again to see if this is the problem.

David:

In the Autogem settings, uncheck the remark "move or delete existing points" and try again.

I unclicked the box and remeshed the model.  I ran the model and got the same problem.

Do I need to add new points and try again?

Do you actually pick a point on the screen? or did you actually make a datum point? if you did that, it should still be there and it should not have been removed after you unchecked the box. In that case, my proposal simply is not the one you need. Sorry.

Datum point is the way to go.
