why it don’t draw in civil 3d but appears in preview and don’t show a warning or error?
No se dibuja en Civil 3d, aunque solo haga un círculo no se dibuja en civil 3d aunque en la vista previa me lo muestra bien y no me da ningún error o advertencia.
So currently you are working with Dynamo geometry, which is actually separate from Civil 3D / Autocad / Revit geometry / entities. There are nodes to convert back and forth.
It looks like you’re missing the last two nodes as input to “block”. I do think the latest versions have set the active document by default. And Layer input needs to be a string or left empty for a default value.
If you don’t have the Civil 3D nodes and you are using Civil 3D there might be an issue with your Civil 3D profile, and it is being treating it like vanilla Autocad. But to push those solids from Dynamo to Autocad / Civil 3D you would need the nodes are your highlighting, yes.
Have you tried without the layer input or by using a single string to ensure it’s adding to one layer?
I recreated your graph in Civil 3D 2026 and it created the solid in the drawing file fine. It appears like your installation may be missing parts of the dynamo tools and maybe the install is not correct. What version of Civil 3D are you running?
