Composite profile callout and positions question

[[Th...]]

Hello guys, I'm new to Calypso. How would you guys do the composite profile callout? Lets say Datum A is the top surface. Datums B & C is middle of the window.

Do I do the positions on the 10x holes as a pattern or individually? Does it matter at all?

The position is fully constrained so you can do individual position call outs or 1 best fit bore pattern with no rotations or translations in the best fit window.

To do the lower tier of the profile, it will require free form surfaces or curves.

Gotcha. I have both FF and curves. I would just call out two profiles individually with the one profile using Datums A,B, and C and second profile with just -A-?

If you define -A- and leave the others blank, doesn't it revert to alignment ? I thought the preferred method was fully define Datums and then allow translation and rotation ?

I believe that only happens with positions.

Unless a profile is fully constrained, you will not get a result when using a cylinder or plane. If you're evaluating a free form surface or curve, best fits will be applied where not constrained. A good way to verify what is happening is to open a default printout window. In the example below, I created a free form surface and recalled the points from a plane.

Eventhough it is completely constrained, you can work with best fit bore pattern because it can save a lot of time instead creating 10 individual true positions, also you will get the best fit graph.
I rarely worked with individual position.
