I have files that look like the image below, cogo points within polyline rectangles. The rectangles will be in different layers (represented by the different colors here), and I want the cogo points within each rectangle to share the same layer. This example is small but the files will be much large…

Hi @V0rticity , The key part of this problem is figuring out how to identify which polyline a point is contained within. There’s a couple of ways you can do it, and here’s a few ideas that utilize Dynamo geometry: Create Dynamo surfaces from the polyline curve geometry and then check every point a…

Looks like a good approach, but I have set up the script exactly and it is throwing some errors and does not run. The first two Object.Geometry blocks give the error “Dereferencing a non-pointer” surface.ByPatch gives “Object reference not set to instance of an object” Geometry.DoesIntersect give…

What is your input? I can’t see that you have added any point and polylines to your selection?

When I changed the first two blocks to user selection, everything works perfectly, but I think the issue is in how points and polylines are being called? Is it valid to just feed a code block into an object? [image]

Zach probably used the code block to visualize the input for polylines and CoGopoint and then he wrote the description above the variabel. I use code block a lot as a breakpoint when I forward result or inputs from one part of the graph in to next. Before 2023 this was a must have because we couldn…

What is a good way to automatically select all polyines and COGO points without having to select them manually? Those should be the only items in the files I am using

The same way as I did in your other thread. Select by Object type or by Layer. Then filter by boolean mask if you have to.

Got it! putting it all together now. I still get this error on the last block but the output is correct. [image]

What are the inputs to the node, and what are the results? Post a screenshot showing the previews of both.
