Changing nominals for 2D curve

[[Mo...]]

I have a 2D curve from a finished part CAD model, that is a closed end "circle".

I need to check this curve on a part with a taper, 2 different heights and different "diameter".

Do I go:

2D Curve Nominal Data - Modify Nominals - Nominal Geometry Manipulation - Modify Nominal - Translation - Length

and enter the amount to change the size?

Is the geometry a cone, or similar? You want to scan two circles and different depths? 

Did you slice through the model to create the curve? I'm asking these questions to make sure I understand exactly what you want.

Slice the model at the called-out depths, creating two curve segments. If the surface is tapered, you might want to use 3d curve.

Using Length as you marked will move nominals in direction of nominal vectors - aka make diameter bigger/smaller.

To move curve along X,Y,Z it's on another tab "Coordinate axes direction".
If you are lucky and it's only translation in one axis, then it's safe.

Otherwise i would preffer copying this curve, changing it's alignment to have origin and vector from original circle, and just translate.

Another option would be making alternative circle, it's strategy and making new curve from this circle's strategy.

I have a finished program with no taper. Before heat treat our process puts a taper on the minor dia (see attached pic).

I'd like to modify the finished program to the sizes on the process specs before heat treat.
