Hi all, I am very new to dynamo so please excuse my lack of dynamo terminology. so I have a cad file with a civil 3d surface and a grid of cogo points showing the elevations of the surface at the 10 ft by 10 ft grid. image “grid line 3”. am trying to create a script that automatically draw a 10 ft …

Hola amigo @yuben112 buenas. there are multiple ways to make lines or directly polylines, using start and end, or by using groups of points, take a look to the topics of lacing and levels in dynamo primer, seems you are progresing well, i let you also the link a couple of post for basics of C3D Dyna…

Yes. one line between two nearest points, if the elevational difference between the two points is more than 0.02 ft. My intention was to populate the horizontal (ish) lines with one script thread and the vertical lines with another script thread.

Thank you, Jacob. Please excuse my lack of understanding and could you elaborate on: transforming to an orthogonal state. can you recommend a node name? grouping and sorting. Does sorting a group of points by X value and y value re-arrange the coordinates of my points? All the points need to stay…

Thank you amigo, your posts are very helpful. I might incorporate the “layer.create” node in my script. I have been having troubles with the linebytwopoints node. in my application, i needed to use a base point with particular coordinates from a state plane coordinate system and then create an arr…

To answer your second question. Essentially I wanted to create one group of lines that start from one cogo point and then connects to the nearest point to the right. Then a second group that connects all cogo points to the nearest ones below them, plus the conditional formatting. I am not very fam…

Generally I used a word directly in the node name to help you find stuff, so if it feels like you are missing nodes or you aren’t sure which nodes you need check the prior post. If you get stuck post an image of your canvas, using the ideal process to export your workspace as an image . [image] y…

Amigo @yuben112 buenas. broo, you have a real challenge here, i’ve try it a gemetric solution but your CS and distribution of cogo poins has not a clear criteria to group the cogopoints, also they has no metadata (RAW or description) that allows to filter either, by lucky the cogopoints are sorted i…

Thank you, Jacob. I will give it a try.

That’s amazing. That lisp did exactly what I needed! Did you make that lisp yourself? care to share? thanks.

Hi @yuben112,

I would take a look at Civil 3D 2025.1 when you’re able
