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.
