Grasshopper Import SHP in Rhino 8

Grasshopper

Has any one else experienced issues importing SHP files in Grasshopper in Rhino8. i get the following error:

  1. Error while parsing nz-building-outlines: Could not load file or assembly ‘System.Data.OleDb, Version=0.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51’. The system cannot find the file specified.

But the same file works fine in Rhino7

Hi Richard -

Can you please upload that file that works in Rhino 7 but not in Rhino 8?

HI Wim, thanks for the reply but this forum won’t let me upload .shp files

I also get the same error. If you find a solution, please let me know.

Hi -

The “same” error means that it works fine in Rhino 7 but not in Rhino 8. Is that the case? If so, please post the file you are having issues with. Note that Shapefiles typically require a .shx and a .dbf file along with the .shp file.

Generally, I’d recommend using a plug-in such as Heron to import Shapefiles. Heron can be installed through the package manager.

Hi, I have find a solution from the forum. Here is the link:
Could not load file or assembly - Grasshopper - McNeel Forum
Plus, refer this link to use .net framework as runtime environment:
Rhino - .NET Core vs .NET Framework (rhino3d.com)

Thanks for the work around, it’s usefull.

SHP component is throwing this error message when trying to load 3D shp.

Error while parsing MIO-92-ContourSite: Shapetype PolyLineZ is not implemented

Not so important as i can retrieve Z info from the db associated file, but is there a plan to update this component so it can get directly it’s contour line in 3D.
While processing sites i often use Qgis and it’s quite usual to get some shift between shp and db files wich needs manual edition of the db files.

Hi -

This is fixed in Rhino 8.9
→ RH-82504 Grasshopper: Import SHP - .NET Issue

There are no plans for new features or other enhancements of this standard Grasshopper component.
Have you tried the Heron or ShrimpGIS plug-ins to see if those handle 3D shp files?

Really quick to fix it :wink:

Yes tried Heron at least, but fall back on standard component for the moment, as it gives me more control.

Hello,
I get the same issue here. Import SHP file works fine in R7 but in R8 gives the following error:

  1. Error while parsing All Buildings 3: Could not load file or assembly ‘System.Data.OleDb, Version=0.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51’. The system cannot find the file specified.

Please see attached the file I’m trying to open.
Many thanks,
Yoav
