I want to create a command:

My selection set consists of dbpoints that exists on my drawing and they are more or less in line

I create a new point3dcollection with this db points

I want to create a 3d polyline based on this point3d collection

My problem is : how to sort this point3d collection based on a picked start point and picked end point?

The only ideea I have is:

from start point i calculate the distance to each point3d from collection and based on the results i sort the point3d collection based on distances

Can somebody have an input on this?

just stumbled over kean's blog on sorting a pointcollection:




he's using the x-xoordinate as criteria but in the comments below there are references to expand on, more like the problem you state, and a step further in his follow up blog.


hope you'll find this useful.
