RPS alignment issue

[[Gr...]]

Hi everyone,

I would like to understand what happens if the angular deviation is too large when aligning the physical part with the CAD model.
Since point B1 is located on an inclined surface, is this the reason why this warning appears?

If you have only those 4 points, then i am affraid it's too low number of points for stable alignment.

Sometimes you can help yourself with changing that green icon ( rule ) to apply when needed.

Hello Grace,

yes, the normal direction of the points should be as close as possible to X/Y/Z direction of RPS.

The larger the deviation the larger the possible (repeatability) error, as the part is not aligned

into the direction the actual point (intersection with mesh 41,4° from RPS direction) is measured.

If there are no such points like in your example, RPS might not be the best method to evaluate the part.

Best regards,
