I want to create a Dynamo script that can export object geolocation and attribute data to either an SDF or SHP file. The objects could be polylines, blocks, points, etc. Basically, I want to have the same functionality as the MAPEXPORT command so that I can automate the process of selecting differen…

@Andrew_Hannell What we currently want to achieve is the following: C3D (polygones) -> Dynamo (SHP) -> Infraworks (SHP) Maybe DynaMaps can help us to get the polygones in Dynamo, in Dynamo we need to provide a Python node that can export the data to SHP format (as indicated by @Paolo_Emilio_Serra…

Hello, why not to export to sqlite? https://knowledge.autodesk.com/support/autocad-map-3d/learn-explore/caas/CloudHelp/cloudhelp/2021/ENU/MAP3D-Use/files/GUID-B4CD55ED-560D-42C7-8348-66AE770B2342-htm.html https://ironpython-test.readthedocs.io/en/latest/library/sqlite3.html

I’d start here: pyshp · PyPI C3D is irrelevant as you learn how to use that. Just write a few polygons or whatever out to SHP. Then transition to D4C3D and a real data set. Then work on the import step.

You might be over-complicating it. If all you want to do is export stuff to a shapefile- MAPEXPORT will do just that. I would do the following: Carry out an initial export of polygon geometry to a SDF file Load this SDF file back into C3D, and add any attributes etc, or use C3D to edit the data- …

Do you have experience with this Drbohlav?

[image] j.boonen: C3D (polygones) → Dynamo (SHP) → Infraworks (SHP) This is my method as well. I’ve found that MAPEXPORT is the easiest, but the problem is that I typically want many separate SDF files to import into InfraWorks as coverage areas because then they will show up separately in th…

@zachri.jensen Is it true that we still miss the output (Python node)? [Fig. 1] Fig. 1 [Fig. 2] Fig. 2 Thanks in advance.

@j.boonen I’m not sure why it’s like that, it doesn’t do that on my end. Anyway, here is the code, it’s just a few lines to send a string to the command line. import System from System import * output = "Error" inputList = IN[0] app = System.Runtime.InteropServices.Marshal.GetActiveObject("Autoca…
