How can I measure how perpendicular a laser is to a surface across a distance

I am a Computer Science student that has a personal project to do. I decided to try and take on a project for a company, and one of the things that I need to measure is how perpendicular a laser is to a surface. The surface is non-reflective, and I…

Is there a way to fix 'bad' surfaces in Solidworks?

I'm trying to create a smooth blended fillet on the outer edge of a part with fillets around it's corners in Solidworks. The results I have are pretty much what I want it to look like but when I check out the curvature the surfaces look pretty…

PMMA-water contact angle in microchannel

I am using comsol to model a capillary behavior of water in an unmodified PMMA microchannel. In literature, I have seen untreated PMMA called hydrophobic. This makes no sense to me because, since its reported contact angle is 68deg, by definition it…

Highlight gaps on joined surfaces - CATIA V5 (GSD)

Is there a possibility to highlight the gaps that occur when surfaces are joined? The gaps are displayed within the command. But after the surfaces are joined, the gap is no longer visible, but it does exist. In the first picture, the gap is…

How to know the maximum offset distance in solidworks that doesn't result a defromed shape

using the offset tool on surfaces can result a shape different from the one offset from, as in broken lines or edges instead of curves like this: is there a way to know the maximum distance i can offset to without resulting such deformation other…
