Minimum distance between two vlax-curve objects

Think about this.

AutoCAD can't find the minimum clearance between two objects as Microstation can.

I think Tony is wrong about this. I wrote an alorithm which works in most cases for any two curve objects. The function is about eight lines of code. Can you guess how it works?

ronjonp:
The only way I can think of doing it is by stepping points on one object and using vlax-curve-getclosestpointto to the other object. Then store the two points and distance in a list then sort the list by shortest distance :?

How'd you do it Joe?

VovKa:
to use vlax-curve-getclosestpointto on arcs one will have to build an approximation and that is not 100% accurate

Joe, I haven't seen the thread, but was the reference to the OutOfTheBox application. ?

Joe Burke:
Kerry,

I don't have time for a full reply now.

I'll just say I think Tony meant vanilla AutoCAD. Does some vertical app have a minimum distance tool?

More later...
