Profile of curve to TWO datums

[[Ba...]]

I am misunderstanding something with profile. I created 2dcurve and attempted to report profile as shown below.
Calypso will not allow me to select the 2dcurve for the feature, so I tried 3dcurve and was unable to select that also.
I do not have freeform. Any thoughts on how to report what is on drawing?

The most practical way would be using profile of a line produced by your 2dcurve, along the zone required. The worst case of all sections would be your answer.

A couple of notes. Calypso will want 3 datums to calculate profile, and it would not allow you to select 2dcurve because you were using a profile of a SURFACE characteristic.(3d)

I was successful getting results using the line profile with NO datum reference and sent results to engineering.
I wanted to be certain about needing 3datums and the feature needs to be 3d (plane, cylinder, cone, sphere...features allowed when selecting element). Now I am curious if I could have measured the area X-Y as a feature other than a curve, and what would that be, would it be valid. I can request Drawing change to line profile but engineering would like me to reach out to those who have more experience first (and I wonder...).

I do not have curve or freeform. So in such situations, I use "general surface" under Features > Additional geometry.
Simply open the feature and start clicking points onto the CAD surface. You can use this feature with surface profile characteristics.
Measurements may take a while as it will retract to clearance plane after each probing.
Additionally for profile to 2 datums, you can create a geometry best fit alignment and use this surface to constrain the last degree of freedom left.
But in this particular case, you can also use one of the 10 holes as tertiary datum.

I have not worked with general surface, did you get good results using general surface?.
His datum reference frame is fully constrained, datum A constrain three DOF, datum B is a pattern which constrain reset of the DOF. He has to use geometry best fit for datum B.

Without the entire print it appears to me: the plane feature is Datum A, the center of BHC is Datum B,(you could use one hole as tertiary if needed), and the Profile of a surface is comprised of a plane and Torus 360 degrees around flange. IF this is correct, your result is inadequate. You might select those areas and see if they are regular geometry. I don't think Torus will populate in Profile characteristic. My suggestion of using Profile of a line was intended to take a slice in multiple places about Datum B. Ideally you want the entire surface but you may not have the options without freeform.

I was unable to use "general Surface" as a feature. It consistently gave me a system error. I am unsure why. So I created a plane from the 2d curve, Surface Profile - feature plane - AB and one of the holes. This looks to have worked! Line profile No Datum was .0051, Surface Profile controlled .0031. Do you all feel this is valid?

As Shabu stated, you need to use all of the holes that comprise -B- and best fit them per your print. Level and origin to -A-, and Best Fit Bore Pattern all 10 holes, which is -B-. Then use that created alignment to evaluate your curves/surfaces profile to.

I have used general surface and it does give me good results but I only use them if absolutely needed because it takes a lot of time to measure and analyzing the results using plotting tools takes some computational power and time. I do cross checks too by creating features where possible and comparing the results to that of general surface; I have found the results to be similar.
Torus surfaces are where I would need to use this feature as it can be used in profile charateristics.

Was it giving you a system error while editing the feature points or something?
General surface is problematic with any kind of edits. You have to delete the point entirely and click points on CAD model again. I try not to do too anything other than clicking points on CAD model or changing clearance plane. I already have my stylus and stylus system selected to the desired ones before clicking points on the model.

They system error happens as soon as I select it as a feature. I cancel and It does place it in the feature listing. I open to enter points as strategy, error if you double click to open but selecting open was ok. Points from model would not populate in strategy. I was able to probe points in. OK gave error, Execute worked, but gave error. Profile would not let me select it. With so many system errors I felt it best not to use.

Maybe a software issue then. I am using Calypso 2016 and it works for me.

Calypso 2020. Guess I should recreate error and send report off to Zeiss.
