AC-GH Connection Mesh node - APIERR_BADINDEX

Hi,

 

I'm trying to clean up some meshes with Rhino + GH and I would like to use the GH connection to generate a cleaner topology in Archicad instead of relying on the "import surveyors data".

 

However, the Mesh component gives me the following error:

I'm using a projected grid of points and the boundary points as the input and a planar curve for the boundary:

Any ideas why I get the message? I can generate walls for this curve, so the connection is working.

AC palette is looking like this:

GH palette is looking like this, I'm using the default 19723 port:

I am using AC26 INT b4019 with Rhino 7 SR28 (7.28.230421.13001) on Windows 10.

Thanks!

FYI, the "Place Mesh from Surveyors Data" command also fails to create the mesh, the popup warning contains the same error message.

I've attached the example .txt which I tried loading. After selecting the file, I get the import window as usual:

After I click OK, the bounding box and contour of the soo-to-be mesh is shown, but when I click to place it, the APIERR_BADINDEX message pops.

This workflow worked numerous times before, I didn't have to do such a thing recently, I have no idea what goes wrong now.

FYI 2: the attached txt imports into AC24 INT b4018 and AC25 INT b6000 without a problem on the same machines (the PC as described above and a MBP M1 Max running Ventura 13.2.1 and AC26 INT b4032 - Apple Silicon version).

 

As a workaround I can copy and paste the meshes to AC26, but I would be happy to get this resolved.

I run into the same issue when trying to create a mesh in GH and send it to AC 27. It is being shown in Rhino/grasshopper but apparently the geometry does not get sent over to AC. any fix for this?Screenshot_4.png

In my case it was generating the mesh very far away from the 0,0,0 point. Was not aware of where the reference point of the mesh was. 😉

Didn't find the answer?
