Helix path inside sphere

[[Ja...]]

I am trying to run a helical path inside a small half sphere. In the strategy of the sphere, I can select "Helix path". The automatic path shown goes up from Z-0, instead of down into the sphere. Target height is .0815. I can change that to -.0815 and the path switches down into the sphere. But I think it is still looking for the outside of a sphere and my probe crashes outside the edge of the sphere on my Z-0 plane. I'm sure it's just a matter of changing something to make the probe look for the inside of a sphere, but I can't figure it out. Any help would be appreciated.

When you first open the feature window of the sphere, there should be an image in the top left corner of the window that looks like a probe touching a surface of either an ID or a cylinder or an OD of the cylinder. Try clicking this so that it is measuring the inside. I've noticed that this sometimes reverses when measuring a sphere.

Brendan,
That does change the little picture, so it looks like it will scan inside, but the probe still tries to start outside the sphere.

The only other things that I can think of that would cause that would be your clearance plane, your retract/clearance distance, or your approach parameters of the probe (whether the probe is trying to probe normal to the face, or the search distance before nominal position). All I can suggest is double check all of those.
