hello, I am trying to create a solid sweep along a polyline. I actually have it working in small sizes but not in large ones. I get the self intersecting error no matter which node I try. How do I circumvent this issue? I am thinking I need to somehow track the normal plane along the entire run, and…

I cant seem to set my rectangle to loft to be on the edge of the line in like the picture in my original post. So I cannot loft like you suggest,because my rectangle is centered on the sweep path.

You could try to use Rectangle.ByCornerPoints with Curve.StartPoint for the first point or move the profile with a Translate node: http://dictionary.dynamobim.com/#/Geometry/Geometry/Action/Translate(geometry_Geometry-xTranslation_double-yTranslation_double-zTranslation_double)

I tried this and get the error message which I cant create the rectangle and dont know why.Please advise. [image]

it appears that my rectangle is failing because dynamo cant figure out which point is the corner points and is drawing the rectangle in the wrong sequence. they polygon node show this well. Any ideas how to fix this? thanks! [image]

Try to sort the list of points using List.SortByKey + Point.X / Point.Y / Point.Z as keys

@Yna_Db , Ok, that sounds perfectly reasonable, but you will have to forgive me because I am afraid you are over estimating my dynamo skills. I cant tell you how many times I re-read the List.SortByKeys node definintion in the dynamo dictionary, and I still dont understand it. Do you think you can e…

Sorry, I did not think about mentioning that: Point.X / Point.Y / Point.Z are nodes, see here: http://dictionary.dynamobim.com/#/Geometry/Point/Query/X A List.GroupByKey node could also be useful in the process: [image]

Im sorry, I still dont understand what you are hinting at. What are you trying do exactly? I did what you did, but I just got failing nodes: Please explain. [image]

I cannot right now, but see if this helps better: [image] Point list in sequence Ok, feeling generous. grinning Should solve your problem @thethtarzaw Part of an upcoming package. Node Description: Takes a list of unsorted points and orders them (clockwise/anti-clockw…

This node seems cool. However, it seems to be dumping out one of the points for no reason which turns my would be rectangle in to a triangle. [image]
