Hi Jens, any update on this ticket? Are you working on a solution for enhanced visualisation of the scan data during scanning?

1st reason can be not exact model. 2nd reason - did you first alignment from extracted features?

"Hi all, I'm consistently running into an issue in Calypso where extracted CAD nominals don't perfectly match the 2D drawing coordinates. For example, a circle dimensioned at exactly X=50.000 on the print extracts as X=49.9561 in Calypso. The circle's diameter extracts perfectly, the CAD geometry is correct, and I am using the proper extraction tools and alignment.

@Alaa Nwesry Not that I am aware. This task is much easier when handled outside the software with an automated script. Do you have any experience scripting?

How that part looks like? Curve in one plane or it goes in all three axis? I would bet that secondary alignment is somewhat rotated and moved. If you want to have less red points, then increase search distance on a curve. At least you will be able to see what is scanned.

I've had a few parts with this scenario. I used an RPS alignment. I measured the two pads at the same height as planes/recalled them into one plane/recalled the one plane as a point. Next, I measured the other two pads as planes and recalled them into points. I then plugged them into the RPS alignment along with my datum B and C features.

yes, it is possible to set limits on a global or per stylus system basis - https://portal.zeiss.com/knowledge-base?id=3366633

Bump. Still running into this issue 😞 Has anyone seen this before?

Does Observer require a dashboard, third-party software? I pull the ProgramDurationRecord.xml file into excel and chart it, it's a PITA.

Yeah, the name Loose probably needs to change - lol. Two big changes from 2023/2024 to 2025 are the fact that we can do FFS inside of the new Profile, and now you can create an Alignment from the DRF that is created inside a GD&T characteristic. The new GDT Profile in 2025+ will have virtually all of the tools that you need, you can even do unequally disposed profile or UZ profiles (the software automatically sets it up based on which standard you are using).

I'm in business now gentlemen. The tips in this thread really got me going on way more than just planes. All was very much appreciated. Matching my cmm and granite checks.

I *believe* what I did last time I encountered this situation was to: Scan each pad, and create a Geometry Best Fit Alignment from them Create Maximum Coordinates for each Datum Pad (relative to the Geometry Best Fit Alignment) Offset two of those Maximum Coordinates by the nominal distance to the other two Create a Plane, using the two Maximum Coordinates & two Offset Points

Awesome, thank you. I hope there are continued improvements to it in next release. OMG Zeiss is now on the A.I. Train ...

Looks like Common Datum solves my alignment question about bore patterns.

I'm glad your issue seems to be resolved Jason. For anyone coming to this forum in the future, here's a Knowledge Baset Article on the topic - https://portal.zeiss.com/knowledge-base?id=454224

Thank you, Zak.

Having done this numerous times throughout the years I've been using these systems, 100% beneficial to the programmer. Great idea.

Check it out! https://portal.zeiss.com/academy/video-tube/imt/87496/Cee6NyY5M3YMmcbBrbzdSv This video provides an overview of the New GD&T Engine in CALYPSO, including availability by version, setting the applied standard (ISO vs. ASME), and key user interface enhancements. Additionally, a variety of application use cases and new function highlights are also illustrated to demonstrate the power and capabilities of the New GD&T Engine library.

We have a Zeiss ACURA CMM that has started shutting the drives off for no reason. We have 3 CMM'S in the lab attached to the same air supply but this is the only one giving us a issue. Looking for ideas before I call support. Thanks

Thank you, Richard, You're always very helpful. I really appreciate it! Something about checking "Loose" makes me feel uneasy in measurement software. lol I'm measuring some fairly tight profiles and am trying to coordinate with outside vendors on results, so I'm really trying to make sure I'm doing things as accurately as possible. Does Calypso 2025 have the same behavior in the GDT profile? I want upgrade but am holding off as there seems to be some bugs still being worked out in 2025.

I would generally prefer to use the standard geometry if I can - mainly because I can filter/outlier elimination if needed. You can use an alignment inside of the GD&T engine, but you have to switch over to "Loose".

One more link from our side 🙂 How to Evaluate the Distance Between Planes?

Hello smart people! I'm trying to get up to speed on the new GD&T engine and profile characteristics. I have a couple of questions... 1) I get different results if I use the feature itself (a cone in this case) as opposed to using a freeform surface created from the cone in the GDT profile characteristic. Which is the correct way to inspect profile? 2) It looks like you can't use an alignment in the GDT profile characteristic. For example, I used to use a best fit alignment created from a bore pattern in my profile characteristic to use a hole pattern as a tertiary datum. How would I do that in the GDT profile characteristic? Thanks as always for your help! BTW... I'm using Calypso 2024
