I'm trying to thick a surface 0.5mm to Side 2 and I'm getting this frustrating message "Face which failed check". Any suggestions what to do?
Just ZIP the native Solidworks file. No need to compress the file as a RAR and ZIP.
I think I mght found what is wrong... if you increase the offset value to about 5mm you can see there a gap forming at front, maybe something is wrong with the geometry there and Solidworks can't seam the two faces together.
It does look like something is not quite right where the four faces come together. Is this your own surface? If so, perhaps you can build that area in a way that is more robust. You might check to see what the radius of curvature does near the corner.
If you can't do anything else, you might try trimming out an area around the corner and then put in a Fill Surface with tangent edges.
I didn't open your file, but try running the part checker. It could be that your surface body has an error. That will often stop later features from working.
Just performed the check, didn't manage to find any errors.
