I want to generate a simplified non-coplanar mesh for clash detection.
Which native autocad geometry can be addressed by dynamo?
I thought Meshes… but there is nothing showing up in Advanced steel or Civil 3D.
I haven’t found an Autocad Geometry that Dynamo can’t work with, but you might need to make a custom importer.
Is your geometry coming from Dynamo to AutoCAD or from AutoCAD to Dynamo though?
Both ways.
The Coordinates are provided by either
-the positions of blocks in Autocad, directly or by a eattext routine.
-the points defining 3Dpolyline.
After processing, the output might be again polylines, but a 3D mesh
-might be easier to address later, for the clash detection.
-give a good tactile representation in a extensive Coordination model.
Look into the Civil Connection package - it’ll do most of what you’re after if I’m not mistaken.
Let’s have a look, I do find the Package.
I do find something similar over here.
Polyline3D to Surface - Civil3D - Dynamo (dynamobim.com)
@mzjensen , can you help me out?
I Find strategies, but the only one that generates copy in autocad is the line.
Extrude line might be the most compact solution, but no geometry shows up.
Mesh.by geometry would give more possibilities, but nothing shows up.
For the surface I need to find how to close the lines first.
Please find the graph attached.
What is a good method to create surfaces or meshes from Coordinates?
Kind regards,
Willem

For Face.ByGeometry, you’ll need a Dynamo face. You can get this using the Topology.Faces node.
Mesh.ByGeometry works fine on my end. Which version of Civil 3D are you using?
The version is Civil 2023
Face is running now, but nothings shows on the Autocad side.

I just tried your graph in Civil 3D 2023 and the both the face and mesh approaches create geometry correctly in Civil 3D. Are you sure you are zooming correctly? Try running ZE to zoom extents.
My recommendation is to create a mesh. This sounds like the best fit for your requirements.
My Colleague get’s this.
Civil:
Dynamo:
I never experienced such flaws regarding Dynamo on Civil when addressing native Civil copy.
How can we proceed on this?
Is there something I can do to test?
Hi Zachri,
I did some more testing, and feeded the script with the points in a different order.
more copy is being drawn on the Civil side.
I can iterate all day.
Is there some explanation on how the scripts works?
I can imagine the indices indicate on rectangular or triangular infill in case of a planar or non-planar translation of the baselines…Both would be nice in a preliminary or final design.
What is the configuration to get a mesh with 3 coplanar parts like this?
