Hello everyone,

Here is the question. I have two space curves, and I want to find a point (location), with the known distance to the two curves. As the pic shows, the distances of the point to the short and long curve are 1.9 and 2 mm. Is this point unique? And How can I find this point (location)?

My idea is like this:

1, create perpendicular plane for each curve, then draw circle with the radius as the distance;

2, move the perpendicular planes (circles) along the curves until they have tangency.

I may do it manually, however, I donâ€™t know how to realize it automaticaly.

The curves are here: spacecurves.3dm (29.2 KB)

Any suggestion and comments are so appreicated!
