Surface comparison peak colours missing -Zeiss inspect

[[Pr...]]

Hello,

I am comparing surfaces from CAD model and scanned part of a product.. I do prealignment and then ''Surface comparison on CAD'' . Problem appears on surfaces that have greater values than my set scale. They remain grey even when I hide other geometries. If I set coloured scale to be +-0,5 mm, then surfaces that have values over 0,5 are grey instead of dark blue or dark red. 

When I did same type of comparison on coworker's PC (he is having same version of Zeiss inspect) - it worked fine. I then saved and imported that project to my PC and when I opened it it also worked fine. But I can not repeat the same steps and get same result on my own.

Thank you for replies!

Hello Primnoz,

please open edit creation (f4) of surface comparison and share a screenshot. My guess would be that the distance is set too short (or any other CAD-Element is set visible).

Best regards,

If I show all elements it is obviously more gray, but I understand that (first picture). Second picture does not have more than one geometry shown yet the areas that go beyond set scale limit are grey instead of dark red or dark blue, as it is marked on scale/legend (as seen on pictures). 

If I set limits to higher values it obviously covers all areas (since I go beyond max and min values in this case). But then in some cases the contrast disappears in cases with high and lone high value. And I have seen that it is possible to do it that way-that is why it bothers me. 

And my scanned model exists on these areas-it is not a problem of no scanned geometry available there. 

Kind regards

If you simple increase the 'Max distance' parameter would you see deviation values in the areas which are actually without any deviation value?

I've had some similar problem and my solution to it have been to always hide both CAD-model and the scan to see all of the surface comparison.

If I change max value grey zones stay the same as with previous, much different max value. With deviation labels I get no result (only '???'). My mesh if fully filled and so is imported CAD on these areas.

Unfortunately not working for me. Thank you for your suggestion.

Sorry, but if it's not the simple 'Maximum deviation value' you must contact your local ZEISS support to find out which special data constellation prevents the calculation of the deviation value in these particular areas.
