[Ja...] Posted February 1, 2021 Share Posted February 1, 2021 How do I get my curve vectors to be perpendicular to the plane they are on? I am sure I am missing something simple here. Link to comment Share on other sites More sharing options...
[Ja...] Posted February 1, 2021 Share Posted February 1, 2021 Are the vectors not "normal" to the CAD surface after defining the feature strategy (nominal points) or after (actual points?) The reason I ask is, if the nominals look good, but the actuals don't, it could be your sensor, especially if you're running an XXT w/ RDS. We see "leaning" vectors with our XXT/RDS frequently when using star styli and was told this is normal, according to Zeiss. Link to comment Share on other sites More sharing options...
[Cl...] Posted February 2, 2021 Share Posted February 2, 2021 Open the curve and under the "Nominal Data" tab > Nominal Geometry Manipulations > Change nominal vectors. Also, if some of them are facing the wrong direction, click on the down arrow on the left, above Point No. You can right click on each point and reverse it's vector.

[Ja...] Posted February 2, 2021 Author Share Posted February 2, 2021 What I have is a thin plane that is at a 5 degree angle to the base alignment. I want to create a line profile down this plane using curve. If I use 3D curve, the vectors are good but if I use 2D curve the vectors are parallel with the base alignment instead of the CAD surface. I don't remember having to use 3D curve for a straight line before. Link to comment Share on other sites More sharing options...

You could create an alternate alignment (resources > utilities > alignment) and set your 5 degree plane as your spatial (rotate and originate to whatever you'd like). Now, reference this alignment for any/all features you're attempting to measure on that angled surface (in the feature window.) You can refer back to base alignment on the characteristic side afterwards. This should make any vectors associated with those angled features perpendicular (normal) to the angled surface.
