Can't change nominals on 2023 Geotol

We are working on a plan to update from 2017. In 2017 Xact let you change nominals for GDT outputs....it seems in Geotol it is a slave to the CAD model nominals, which as we all know can sometimes not be what we want.

Is there a way to change the nominals in Geotol?

Thanks.

i think you have to update your theos of the measured feature in order to change the nominals Geotol

This is correct. It's got me so many times.
but you have to remake the report dimensions for it to take the new theos.

The THEO X,Y,Z,I,J,K (and size if applicable) should all be correct at the feature level. This is because incorrect feature nominals will have a detrimental effect on many other things - alignments and constructions for example, not just dimensions. Although the older, XactMeasure style of dimensioning allowed you to edit nominals in some cases, it only provided a way of editing the X,Y,Z. There was no way to edit the I,J,K vectors, even though these values are equally important and needed in order to obtain the correct results - especially for position and orientation tolerances. In hindsight, we realised that we should never have allowed nominals to be edited at the dimension level which is why we decided not to continue providing that functionality for the Geometric Tolerance command.

@neil.challinor,

I don't quite follow what everyone is saying here. We were able to change the XYZ location THEO's of the cylinder feature, but when we go into GEOTOL it is a few microns off due to the CAD model.

Can you change the nominal XYZ location values of a feature in GEOTOL by changing it at the feature level in 2023?

The only way to change the nominal values of a geometric tolerance command is to edit the THEO values of the features that are being referenced. However, if you have a CAD model, the THEOs (and nominals) should already be correct so why do you want to edit them?

thats the issue i have also at times. the model is not perfect sometimes and need to alter the dimensions on the report sometimes to reflect the print.

It's usually the other way round - the model is perfect to many decimal places whereas the drawing has been rounded to two or three, causing what appears to be a discrepancy. The first thing to do in situations like this is to reach out to the customer to establish which takes precedence - the drawing or the CAD (usually CAD in my experience). You can, of course, alter the number of decimal places PC-DMIS displays (with a DISPLAYPRECISION/ command) to get closer to what the drawing shows.
