Thank you.

In my situation, the faces/surfaces are only cylindrical. Always. But one face's curvature (from vEval(9) or vEval(10)), who's normal points TOWARD the origin axis of that cylinder, is positive - and one face's curvature(from vEval(9) or vEval(10)), who's normal points AWAY from the origin axis...

Thanks, it seems just FaceInSurfaceSense is all I need, when does negative curvature occur? I haven't encountered it yet.

"...A positive curvature by convention implies a centre of curvature on the side pointed away from by the surface normal (convex)..." - what does that mean in terms of this method...

@ Snowcrash, That has nothing to do with the thread topic or my original question. I didn't mention my lack of knowledge in sealing solutions or O-ring groove design because it is entirely irrelevant. If you are unfamiliar with SW API, don't bother. Please read the entire thread before you...

The groove is cut into a cylinder for the oring (male or female side) or for simplification, any cylindrical surface should work. don't know how to recognize if inside or outside

@CBL Yes, its possible to do it that way, but I'd rather not try to reference adjacent faces and edges due to fillets or chamfers that may exist on seating face and open edge... if I can't come up with anything easier I may have to resort to that, thanks.

Hey Forum, I'm designing a macro that automatically creates and adds a custom length o-ring to an assembly based on the cylindrical groove surface diameter. My problem is if its an inside groove, the OD of the oring must be the diameter, or if its an outside groove, the ID of the oring must be...

Sorry, thats what I meant to write, center coordinates. Please neglect this thread as I have gone in a different direction. Thanks though.

Wondering if there is way to get the coordinates of circular edge of a model inside an assembly? See attached picture for more details. SolidWorks obviously can... any help?

@CorBlimeyLimey, in my case, those faces are not accessible in all situations (fillet or chamfer before adjacent faces). This is for a macro and although is possible, the amount of coding to acquire the faces, create planes, etc.. is far more work. I will use your sketch geometry idea instead...

Your second choice is what I'm looking for, I want a "mid-plane" between the two edges, but reference planes from edge references only include coincident... see photo attachedhttp://files.engineering.com/getfile.aspx?folder=df68598e-0e11-41d0-b3aa-a64f1c26d704&file=refplane.jpg

Is there is a way to define a reference plane between two concentric edges?

Hey forum, I've been on here for almost a week, and I can't explain how grateful I am for all your input. I have another question about SW API. If you have a selected component, is there a way to check if any of its planes are parallel with any of the assembly planes? I know how to select...
