@Benjamin Bellville, hang in there. Your problem is real, but it's solvable. My first CMM gig was measuring large machinery that sounds similar to your current challenge. It's entirely possible to measure parts that are not orthogonally perpendicular to the CMM's coordinate system, including parts without planes and other prismatics. What Peter and Martin suggested regarding space points vs CAD points should solve your point placement issue. There are several different types of points in Calypso. The CAD point option tends to snap points to the CAD entities as though they're magnetic. Space points should work better here, even though the names sound counterintuitive. Regarding the alignment challenge, there are two options I would consider: 1. Non-standard alignment options such as best-fitting / RPS (reference point system). You can use a cluster of points to define your workpiece and constrain degrees of freedom. This works well on parts without prismatic features like planes, cylinders, etc.. 2. Standard alignment with a defined rotational angle from the "Special" menu. If you can create a standard alignment but just need to define that it will be clocked at a known angle, you can use the special button in the alignment window to rotate the alignment by this angle.

I really don't know the difference between a point and a surface point. As for extracting planes from models, I cannot. Most of the surfaces are not recognized as a plane by the software. I can click on multiple points on the CAD model and iterate through

The active probe is also considered when clicking points on a model. (If your probe is angled, and constrained to the coordinate system of the CMM, your points obviously will have to be too!)

You could also do a 3d best fit alignment and loop the alignment

Thank you. I will try this as soon as I get a free seat.

Sorry, I cannot share pictures or really much more information.

I'm not entirely sure either. As you can see, the graphics I provided is below the nominal and it shows slightly to the right of the midline on the scale.

Never looked that hard at the scale, usually looking at deviation. Pulled up a report and noticed the first dimension graphic appears centered around the means even though it is above the means dimensionally. Maybe scaling because of the large tolerance on the dimension? Again, never paid much attention to the graphic, I believe it is intended as a graphical aid, but you piqued my curiosity.

Are you clicking points on a CAD model with the "Define points" option? This defaults to the Touch Point evaluation method (snaps vector to nearest coordinate axis) and rounds your nominals to the "Round-off measure" setting under Extras->Settings->Measurement... Instead try the "Define a Space Point" option. This will maintain the nominals from the CAD model and set the evaluation method to Space Point, which also uses the correct vector from the CAD.

@Richard Shomaker I don't have FFS, but I assume you can use formula in recall feature points. I would use PCM to create a list with desired elements and recall that list using formula. You have to change a loop index in every element, but you can come up with some "automatic index extract" from name of element or something and you just copy paste that element x115 😄 nameOfElement = "Point" noOfElements = 4 noOfSections = 3 loop = 1 recallElementsList = "list(" for i = 1 to noOfElements for j = 1 to noOfSections recallElementsList = recallElementsList + qm() + nameOfElement + "_" + i + "_" + j + "(" + loop + ")" + qm() + "," next j next i recallElementsList = mid(recallElementsList,1,(len(recallElementsList) - 1))) recallElementsList = recallElementsList + ")" //display(recallElementsList) recallElementsList = getParameterNamed(recallElementsList)

Are you clicking only point or surface point? You can also extract plane from model and do points on it - so vectors will be fine

Are you able to share an image of the CAD or part?

I suspect dirt on contact area inside RDS, but i don't own RDS so i can not tell how it looks inside. This problem is only in this position or is it occuring in other configurations?

I did, but there was no improvement.

Did you try restarting machine?

We are having an issue with the probe head on our ZEISS CONTURA CMM, as shown in the video. Does anyone know how to resolve this issue? We urgently need to take measurements. Thank you!! 1790819277603-1342595881688479684-g2617570072669844278_VY7PIJil.mp4

I apologize , it´s confusing, i was questioning if someone used the projected tolerance zone.

Hi Marek, sorry for the late response. Yes, the deformation and clamping force are calculated using the deformation model. A more sophisticated quadratic deformation model used in Virtual Clamping will deliver more realistic results for example. If you use De-Warp I recommend watching the eLearning. It also covers the deformation model. Nanno

Hello Akos, what is circled in the right screenshot is the simultaneous requirement, which was added with Inspect 2026. A positional check with spherical tolerance zone is possible if the datum system supports it. Nanno

Good morning everyone, FYI: development is currently working on this to be more user friendly, i dont know about the planned timeline but there will be a change about this matter with the upcoming CALYPSO Versions. Best Regards Marcel

Sounds like calypso is just super buggy with this and badly programmed. Thank you all for your advice. I ended up starting a clean file and rewriting the program from scratch. I was not that hard of a program and only took about 6 hours.

We have a part that has very few planes that can be aligned to. What is worse is that to fit it in the cmm and measure things it needs to be NOT square to the cmm. After a few hours, I am still working on the alignment process. Without too much detail,I have found that the software is not putting points where i click them! I think that if I can solve the problem if I can figure this out. I have a plane that is NOT square to the coordinate system. I need to place a point on that plane. I click on the model and the point ends up not on the model and not in the location I clicked. The point ends up around 0.03" off to the side and about 0.01" above the model by eyeball estimation. I have tried adjusting the view and this does not fix the problem. I really don't understand how it is picking that location. It forces the ijk of the point to be square to the coordinate system. I can manually fix that even though it fights me. Is there a thread for people who have fought this kind of thing before? I came from using Verisurf, Polyworks, and PCDMIS. None of them had issues with handling parts that were not square to the coordinate system or did not have nice tidy squarish features to work with. Why is Calypso so bad at this?

Hi Meaghan, In the probing system qualification window, be sure to click on the blank box that is immediately to the left of the stylus name. You should see a black arrow appear. This activates the Geometry Requalification option. See below.

Richard, What file explorer is that? Doesn't look like Windows Explorer.

Norbert, do you have some advice where I can find commands I can use there? Just tested the one you've supplied and I find it might be useful for CAD operations without bothering design engineers. Thanks!
