3D View to DWG, Pre-Defined Export Settings


I’ve been searching through the forum but couldn’t find anything that relates to this. I want to export a 3D view with pre-defined dwg export settings so that solids export as ACIS solids rather than a Polymesh, which is the default.

Would anyone know if this is possible? I know Dynamo can get the current settings from the project but i don’t want to have to be setting up dwg options every time.


Use Genius Loci’s package / Archilab and add export as ACIS option
options.ExportOfSolids = SolidGeometry.ACIS

Thank you for that, would IN[6] happen to refer to this part of the export settings?

Was able to get some time for testing and answered my own question, thanks again for your help, export worked perfectly when brought into Rhino.


Would you be able to explain how to incorporate the “full code”? I am trying to export as acis solid and having no luck finding the node to set it as a solid geometry.

Thanks is advance!

@joeydoherty The code is placed inside of a Python Script node, mine looks something like this. Keep in mind i have renamed the python node to be “Export DWG” and i am using Data Shapes to pass through the input data.
