Trying To Understand Sweep and Vertices

[RyanJP]

When I sweep along a curve which was built by taking a grid and running a carve on it, my sweep looks like this-

However my I try to do it on a curve that was created by taking a line, and then copying to smaller lines on the ends and fusing, it looks like this-

 

As you can see the corners are messed up. I assume this has something to do with vertices as the first example contains only 4 vertices and the 2nd has 6. I'm just wondering specifically what the issue is here and of course how I can fix it

maybe your curve has more than one primitive.

Ok awesome that got me one step of the way, was able to use an add node to get it down to a single primitive but now now my point numbers are off, is there a simple way to flip two of them (2 and 3)

yes, you can use dirty way in add sop - delete geometry keep point - then go the polygon >bygroup >write in name group 0 1 3 2 - never use this way  - u must check from the top why u have this issue -

and if u have multi primitive in curve use join sop converting to single prim .

Haha yes- very dirty way to do it. Actually this has helped me to figure out what the problem was when I created the shape. And I was not aware of the Join SOP, so that's great. Thank you!

Use PolyPath to combine primitives.

Polypath -> connect end points, and if your point numbers are still wrong, use a Sort with Vertex Order.

Amazing guys. Thank you. I'm going to use that node all the time!!
