Create polyline circle and scan

Why not use the planar circle scan? It is available in the autoplane measurement strategy.

I would use a basic scan circle/plane with a 1 mm ball on 35.4 diameter.

Thanks for the suggestions. vpt.se, When I choose autoplane, and then pull down the selection for a circle, it seems that just switches the dialogue to the auto measure circle. Wherein, the probe approaches from the center of the bore. I need the probe to approach from a vector parallel to the bore axis.
vpt.se and Jefman, On the measure auto circle dialogue, I did try to setup measurement strategy tab in the lower window by selecting adaptive circle scan, but again I can't get the probe to approach parallel to the pore axis.

I don't know where to select measure "basic scan circle/plane". I would love to see that somewhere. :-)
I played around with the insert scan circle a bit. I think the initvec and cutvec details will be what I need to play with. I am measuring 6 of these features, each of which are located at 60 degree intervals radially about the B datum(X) and the bore axes are at a 3 degree angle from the X Datum and along its radial direction. So I think I will need 6 different sets of these vectors. Probably some way to determine that using pcdmis.

Insert/basic scan/circle/plane.
You will have to :
ASSIGN/V1=DEG2RAD(3)
ASSIGN/V2=COS(V1)
ASSIGN/V3=SIN(V1)
Assuming that your alignment is on the detail C x from bottom to top and Z from right to left, create a local alignment with i=V3, j=0 and k=V2, then create a clear point at x= radius of scan,Y=0 and Z=50 f(for example), disable the clear plane in the scan window and try it... repeat the clear point after the scan, and dimension the plane in the previous alignment.

Thanks, I'll need to do the appropriate trig for each of these but I think I can figure it out based on your description. X does go from right to left, but z rotates from 30 degrees in 60 degree increments. I might just suck it up and just drop the hits manually to get a profile. As you can see this particular tolerance is very forgiving. BTW, is there a way to go back and edit a post. I might like to remove the graphics.

There should be a edit button in the lower right corner. If its not buggy again

You are clicking the wrong icon.

You should be selecting "measurement strategies" and not the actual auto feature selection. The strategies tab looks like a trident.
