[Ma...] Posted August 11, 2025 Share Posted August 11, 2025 Please sign in to view this quote. Norm angle is correct - at least it should be 0 or 360 - it's telling in which direction is Z axis of feature pointing. Green arrows are measured points - are those recalled measured points?

[Do...] Posted August 11, 2025 Author Share Posted August 11, 2025 Please sign in to view this quote. No, the actual direction that the probe travels is perpendicular to the edge that it is measuring. It is just the on-screen image that shows the vector as being off. Not sure why it shows different than it actually travels. Link to comment https://qualityforum.zeiss.com/topic/24179-vector-correction/#findComment-136637 Share on other sites More sharing options...
[Ca...] Posted August 12, 2025 Share Posted August 12, 2025 In evaluation what type of point is set? My guess is you will want plane point and it looks like touch point could be set.

[Cl...] Posted August 12, 2025 Share Posted August 12, 2025 (edited) Is the line constructed from two points? Or is it a measured line feature? If constructed from two points, go into the evaluation settings of each point and change it in the drop-down on the lower right.

[Ma...] Posted August 12, 2025 Share Posted August 12, 2025 What is that "Line Auto Path"? I saw a normal one, where you can define own start/length of a path.

[Do...] Posted August 12, 2025 Author Share Posted August 12, 2025 Please sign in to view this quote. The "Line Auto Path" is what is in the measurement "Strategy". Instead of it being two individual points it is shown as a "Line Auto Path" but since the machine is not capable of scanning, the line is comprised of two points with a step width of .102" in between them.

The probe physically travels in the correct direction (normal to the surface) but on screen the actual points shown appear normal to the X,Y,Z coordinate system.

[Dr...] Posted August 12, 2025 Share Posted August 12, 2025 Hi Please sign in to view this username. , which version of Calypso and service pack are you running? You've mentioned it's an older one from before the era of caliper distances. You can find this information on the lower-right corner of the main menu or under the "?" dropdown > "About". There were some Calypso versions where service patches were released to address normal vector display errors through the ACIS engine. ACIS is like the graphical renderer for Calypso and though it's technically "its own thing," it's very closely intertwined with Calypso. If an ACIS bug is the source of this issue rather than anything in the programming approach, the solution could be as simple as getting a service patch. If you're already up-to-date on your version though, it could be an uphill battle. For one, very old Calypso versions are out of official support, and second, knowledge of how ACIS and Calypso interact isn't something that very many people have.

[Dr...] Posted August 12, 2025 Share Posted August 12, 2025 Please sign in to view this quote. Interesting, that might give us a path forward. On the first service pack for that version (5.6.0400, don't ask me why Zeiss does their service pack numbering the way they do), there was a bugfix entitled "10504: CAD Model vector corrected". If that is indeed what you need, it'll have been implemented in every 5.6 service pack after 5.6.04; ideally we can get you up to the fully updated one, which I think is 5.6.24. The next question is where to get that service pack, and admittedly I'm at a loss here. It's not on the Zeiss Portal, but I'm willing to bet someone within (or without) Zeiss has a copy. If you don't get a response from a Zeissian here, I'd recommend reaching out about getting it.

[Ha...] Posted August 18, 2025 Share Posted August 18, 2025 Please sign in to view this quote. What Caitlin was referring to is the point evaluation mode. You will find that in the Evaluation window for the feature. You can switch between the different modes depending on the application. https://portal.zeiss.com/knowledge-base?id=1007796 1 Link to comment https://qualityforum.zeiss.com/topic/24179-vector-correction/#findComment-136935 Share on other sites More sharing options...
[Jo...] Posted August 19, 2025 Share Posted August 19, 2025 Joseph, I really appreciate you posting that knowledge base article. I didn't know it existed, and it really helps to understand the different types of points. I do have a couple questions though, and I see that you wrote the article. So, who better to ask? Plane Point is described as 'stylus radius correction in the normal vector direction' but doesn't specify nominal normal or actual normal. It would have to be the nominal normal, correct? The point labeled as plane point is shown where the actual normal intersects with the actual contour, but would the actual result be where the nominal normal intersects with the actual contour? Also, I don't fully understand the description of a touch point. My interpretation is this: stylus radius correction will be in the direction of a coordinate system axis. If the probing vector matches the vector of a coordinate system axis, that will be the direction of the radius correction. If the probing vector does not match a system axis, the software will determine the coordinate system axis that is closest to the probing direction and radius correction will be in the direction of that system axis? Is that a correct interpretation? Link to comment https://qualityforum.zeiss.com/topic/24179-vector-correction/#findComment-136987 Share on other sites More sharing options...
[Da...] Posted August 19, 2025 Share Posted August 19, 2025 I don't think that the evaluation setting for a single point has any effect on straight lines and circles. Looking at Donny Fraser's measurement results, the vector correction seems to work well.

[Ma...] Posted August 19, 2025 Share Posted August 19, 2025 I think this will be either software issue as Please sign in to view this username. stated or communication with head and Calypso. If that's a real measured feature, then vectors should be correct. If it would be recalled measured points, then it could behave in some circumstances. I would try install / obtain patch or newer software. Link to comment https://qualityforum.zeiss.com/topic/24179-vector-correction/#findComment-137011 Share on other sites More sharing options...
