Longest/Closest Distance Between Two Objects

Hello,

I have this Lisp MD (Closest Distance Between Two Objects).lsp that can show me what is the shortest distance between two objects. If you type MD it shows the distance value and if you type MDL, it draws a line between them on the closest point distance. It can be useful for you if you need.

But I need the right opposite of it.

I need the Longest Distance between two objects.

I need the number and the line of it.

Can someone help me?

There are a number of places where something like this is checking (> dist x) for longest (

But I need the right opposite of it.

If you are searching for longest distance between 2 curves like in your posted lisp, you have many ways to get those 2 points... There is my sub function posted here : https://www.theswamp.org/index.php?topic=42246.msg507763#msg507763 , which you can use to get furthest point from checking point...

Another way and I think is better is to segment reference curves and then supply point list to Lee Mac's MinEnclosingCircle sub function, after which instead of drawing minimum enclosing circle, you can check 2 or 3 touching points for longest distance - that 2 points that satisfy relation of longest distance would be solution to your task... You can finally draw line or use that data for your needs as you wish...

MinEnclosingCircle - look here : http://www.lee-mac.com/minimumenclosingcircle.html

Sounds awesome,

Thanks for sharing it, Marko!
