Grasshopper VB.NET component does not recognize ON... objects

by Peter Mayrhofer

What is wrong with my Grasshopper installation?

Rhino 4 (latest service release) and Grasshopper (latest version) are running without problems -

with one exception: If I try to run even the simplest VB.NET examples I get error messages as for instance: "Name cos is not declared" (when I wanted to compute the cosine of an angle)...

 

It seems to me that the VB-component has no knowlege of Basic keywords and Rhino-Objects/Methods.

 

Can somebody help me??

Thanks, Peter

    Hi Peter,

    This is because scripting components have now switched over to using the new RhinoCommon library rather than the old RhinoDOTNET/OpenNurbs one. If you still want to use the old library you can - you just need to use a 'legacy' scripting component rather than the normal one.

    Hope this helps,

    Paul
