Points List Order Problem

hi Guys,
Having trouble working out why the order in my points list is not the same in all sections.
i have made a quick 30 second youtube video illustrating my issue. Points List - YouTube

3dm & GH files uploaded also.

Any help greatly appreciated.

This type of jagged data tree branching is always a bad sign and should be taken care of. The trees should have the same number of “levels”.

Something to try: you can sort the points along a curve by the component Sort Along Curve. For example, if you have same number of vertices in each of the polylines (the sections), you can sort those points based on only one of the polylines. That way the order would could be the same.

yes, in this case this input should be flattened in order to get a Closed Brep:

if you use Brep/Brep intersection instead of Brep/Plane (which means you build some big planar surfaces over your section-Planes)
and
for some unbeknown (at least to me) reason you deconstruct and rejoin your brep together…

then the point order is consistent (on my PC :slight_smile: )

I love this community, you are all legends :metal:

@inno I found the deconstruct / join brep issue you illustrated. what was i smoking when i wrote that!
thanks for pointing it out.

@TuomasLehtonen thanks for the tip about the number of levels mismatched in my tree structure. i will be sure to make a note of this from now on
