New to Dynamo, any help wold be appreciated!!! :-{) I thought I would start with something simple, I want to be able to pick an Alignment or a Polyline and have it create multiple offsets left and right and put them on the correct layers… ie… I want to pick a center line and have it create BOC, …

Hi @btillett , Check this out if you haven’t already, it might help you get started. [image] Creating Polyline offset from Alignment Civil3D Hi all, Very new Dynamo user here. I am a bridge engineer in MA trying to find ways that my team can automate or at least speed u…

Thank you for the quick response. Yes, i downloaded that and cannot get it to run… it has way more than i need, I am still trying to figure out enough to get it to run on an alignment I have in my dwg. If I can figure that dyn out, it should help me create the simpler one that we would like to use. …

OK here is a simpler example for you to try. OffsetsExample.dyn (44.9 KB) [Offsets]

Thank you, that looks like exactly what we need. But it does not run. the list is empty? Any ideas why the “Curve” and the “list” would be “Empty List”? [DynmoListEmptyError]

Probably just need to add the layer input on the AlignmentExtensions.GetGeometry node. By default it will get the alignment geometry on a layer named C-ROAD. It’s set up that way so that you could, in theory, get geometry for things like tangent line extensions that aren’t really part of the main al…

YES!!! Thank you… I had tried adding the layer name with a “Input, Basic, String” but that did not work, but when I put the Alignment on the C-Road layer it worked. How would I change the layer to our standard layer for alignments? Any idea what this error message means, or how to clear it so I ca…

[image] btillett: How would I change the layer to our standard layer for alignments? That’s the answer! Just add a string input with your standard layer name. [image] btillett: Any idea what this error message means It means that the geometry is very far away from the origin, which is…

2024.3 update broke this dyn. I tried fixing it but can only get it to offset to one side. Any help would be appreciated. BOC,FOC,EOP,SW From Alignment.dyn (132.9 KB)

Do you get any error message in Dynamo? Create som screenshot from each node to show what they return. Does the original dwg only contains a single alignment?

missed your reply, sorry. Thank you for your reply! i fixed it somehow… I think I just replaced the nodes with errors with nodes with the same name from the updated package.
