"Thanks a lot Florian!See I am not sure where I can get this kind of information (specifically about GH Types and casts), this forum helps a lot and I am very grateful. Quick fix just in case someone looks this up: "

"Hi Tarek, You can use the Grasshopper Types to cast from GeometryBase to Rhinocommon types. 1. Method: List<GeometryBase> geo = new List<GeometryBase>(); foreach (Rhino.DocObjects.RhinoObject obj in objs) { GH_Point p = new…"

Grabbing Points from Layer and Casting Objects to Point3d in C#

Hello,I am attempting to grab various geometries from layers in Rhino and using them as input in a C# component. I used code provided here on the forums in VB and translated it to C# to grab objects from layers:String layer = "Points";Int32 layer_index = doc.Layers.Find(layer, true); if ((layer_index < 0)) return;Rhino.DocObjects.Layer lay = doc.Layers[layer_index]; Rhino.DocObjects.RhinoObject[] objs = doc.Objects.FindByLayer(lay); if ((objs == null)) return;List<GeometryBase> geo =…See More

"Yes there a class definition for Block, but it turns out that the issue is in running a foreach loop on a single curve. For some reason it worked before, although it shouldn't have! Thanks Andy."

Error - Foreach and 'GetEnumerator'

Hello,I've been working on a C# component for quite some time now, and it was working just fine until I installed the new Grasshopper 0.9.0006. That's when this error showed up:"Error: foreach statement cannot operate on variables of type ‘Rhino.Geometry.Curve’ because ‘Rhino.Geometry.Curve’ does not contain a public definition for ‘GetEnumerator’ " I'm going to assume something changed in rhinocommon. What changed? How do I deal with the part of the script that used a foreach loop on curves…See More
