algorithmic modeling for Rhino
I seem to be having a lot of issues, all stemming from casting between the three of these. Here is an example of what I'm Struggling with...
I have an Instance Definition, and want to get all of its objects... so I Do this:
string defName = "Block_01";
Rhino.DocObject.RhinoObject[] defObjs;
Rhino.DocObject.InstanceDefinition myDef = doc.InstanceDefenitions.Find(defName,false);
defObjs = myDef.GetObjects();
That works great. I have a bunch of objects in an array. But now, I want to see which of those objects are nested Blocks... so I Do this:
List<bool> isInstObj = new List<bool>();
int defObjsCount = 0;
while (defObjsCount < defObjs.Count())
{
if(defObjs[defObjsCount].GetType().Name == "InstanceObject")
isInstObj.Add(true);
else
isInstObj.Add(false);
defObjsCount++;
}
Still Goes great. I have a list of booleans telling me if it is an Instance Object. Now I want to get the Instance Attributes of the Instance Objects (such as InsertionPoint, InstanceXform, and Instance Definition). Not to be confused with the Rhino Attributes. But I cannot get the Instance Attributes because it is still of Type RhinoObject. Here is what I want to do (but cant figure out how to):
List<Point3d> instIP = new List<Point3d>();
List<Rhino.DocObjects.InstanceDefinition> instDef = new List<Rhino.DocObjects.InstanceDefinition>();
List<Transform> instTrans = new List<Transform>();
defObjsCount = 0;
while (defObjsCount < defObjs.Count())
{
if (isInstObj[defObjsCount] = true)
{
instIP.Add(defObjs[defObjsCount].InsertionPoint);
instDef.Add(defObjs[defObjsCount].InstanceDefinition);
instTrans.Add(defObjs[defObjsCount].InstanceXform);
}
defObjsCount++;
}
But that doesn't work, Because of the casting issue. This is my end goal, and if I can figure this out, I think it would solve a lot of my confusion. If there is a better or alternative way to do this, I'm up for anything! Any help would be appreciated.
Thanks in advance!

It may be best if you post this on our discourse forum. This is a pure RhinoCommon SDK question after all, and all the SDK programmers hang out there rather than here.
