Parcels - Export Property Set Definitions to shapefile

Hi

We are struggling to find a good workflow for urban design in civil 3d for getting data exported out to GIS -

Our ideal workflow we would like to have is in Civil 3D to assign custom configured Property Set Definition attributes to Parcel Objects in a similar way to how you can in AutoCAD Architecture with AEC Object types ie 'Spaces' - either formula based or automatic ( ie Area (automatic), FAR (manual entry), Area x FAR = GFA (formula) calculations for example  

I see that the Property Set Definition platform is now included in Civil 3D 2017 - However the range of attributes available is very limited for Parcel objects and also the Extended Data Set attributes are seemingly not available on exporting to Shapefile

Any help, advice, solutions welcome

Thanks

Hi - This is an area that we're actively investing in. We're looking at a few different approaches toward how we bridge the gap between GIS and Civil (both moving data into C3D from GIS and then moving design/construction models into GIS / O&M environments). I can't go into details on some of what we're working on but there are some things that we're doing that will impact you sooner than later. 

Near term, we're working on improving the workflow for moving field captured data (e.g., points and feature lines stored in SHP) that include GIS attributes. We can leverage Property Set Data as a way to include whatever attributes were captured in the field. C3D 2017 SP1 added the ability for people to add property set values to C3D labels. Therefore you can include any/all of this information in your production deliverables. We also include the Pset data when moving files to Navisworks and we're investigating adding this information to the online viewer in BIM 360. 

The other part of the near term solution is to export points and feature lines (with Pset data) back to SHP. 

We'd love feedback to help us prioritize other model elements that we should target in this workflow. Beyond parcels, we frequently are asked about pipes (gravity and pressure). 

We'll update everyone as things progress.

Thanks

Hi has there been any progress on integrating Property Set Definition attributes into the MapExport function?

Still waiting for this, any news yet on exporting property data sets along SDF/SHP?

I really can't wait to stop manual re-typing fields in GIS everytime.

If you were to consider third party add-ons, DotSoft's C3DTools contains a dedicated Parcel ShapeFile Write tool that picks up all older Parcel UDP as well as the new AeccPropertySet data and lets you choose which fields to include in an easy to use dialog.

To find out how it works for yourself, request the full working 45-day evaluation.

Hi @stefano.donati 

Take a look at the SHP import/export utility I did not personally try it with  Parcels, but it does work great with Feature Lines and Cogo Points. The utility is available as a plug-in from the Desktop App or Autodesk online account portal to Civil 3D 2016 and 2020-2021

Hope this helps,

That's a nice tool to have but actually it is very limited, it operates with few C3D objects like COGO and feat lines.

The most valuable information to bring in GIS are stored in other objects like pipe networks and corridors and parcels themself.

Actually there is no way to "translate" C3D property fields - pipe diameter, to say one - into SHP property fields. One may think that's an easy task but no, let's export just lines and dots then manually re-type all the infos in GIS.

Anyway, thank you @samir_rezk!

Map export for geometry
DataExtraction for data and then join in GIS?

Depends if an object identifier can be used

Hi, I think the fastest way to extract data from civil3d to shp is:

1) Create a Property Set and attach it to your 3d civil object

2) Select the objects and enter the values (Properties palette - Extended Data tab)

3) Convert Property Sets to Object Data. Object data can be exported with the MapExport command (property set cannot be exported with MapExport). Here I post a dynamo script to automate this process: Property Set To Object Data

4) Convert civil 3dObject to shp compatible geometry element (point, line or polygon). For example, convert parcels to closed polylines, pressure pipes/fittings to lines/points etc. Points, lines, closed or open polylines can be easily exported to shp file whit Mapexport command). Im working to automate parcel and pressure networks conversion to shp geometry (dynamo script).

5) Execute Mapexport command.
