How to find sphere diameter? 1

[aleksandar81]

I have 3 surfaces in assembly ,and I need to find size of sphere that is tangent to this 3 colored non planar surfaces.Size of sphere is of course in function of where the tangent point.

I could not think of a unique way to do it in NX,
but I found this video that may help.

Apply a "3 face" type face blend, then section the model at the desired location and measure.

The image looks like a turbine with thin blades.
I imagine that the question is :" what is the largest mill to fit in between?"
If you can reverse the volume, subtract the turbine from a cylinder, then you can run the analysis "Check wall thickness":
It has an analysis method of "filling the volume with spheres of the largest possible size".

Thank you guys for your suggestions!Actually I needed to find place with min sphere dia.

-and that is exactly what the "Check wall thickness" is intended to do.

The check wall thickness tool mentioned by Toost is a good way to get what you want. If you create a 3 face blend as mentioned in my previous post, you could use the "minimum radius" analysis tool or some other curvature analysis tool.

Both methods include dynamic mouse pointing (minimum radius,Check wall thickness) how do I find the exact spot where the ball lies?
