Perpendicularity whit out flatness

[[Za...]]

I have a problem. Designer want control perpendicularity whit out flatness. According ISO 1101 i must use extracted element and it have form deviation, hi want use associated element whit out form deviation. Is it posible mark at a draw, and is exist easy way do it at Calypso. Now a create theoretical plane and connect it by formulas to actual position and space angles of measured plane. Designer want ad modificator G according ISO 1101-2017 but as i understood id don`t mean that he want.

You probably need to create a theoretical plane and use formulas to populate all the actuals. The form should be perfect. I would probably use outer tangential on the original feature, but if your designer wants you to use LSQ then that's up to him/her. ASME Y14.5 uses a Tangent plane modifier to achieve what you're looking for. But the way it is defined requires the OuterTangential evaluation. Maybe ISO has something comparable.

Instead of using formulas, couldn't you use "Recall One Feature"?

I forgot that was an option. That's a lot easier.

which diferents betwen "recall one feacher" and "recall feacher"?

Quick solution... only use three points. Bam, no form deviation!........

This is a strange request, and my brain can't seem to quite understand what they are after.
