VSTA: read geometry information

robotrix

Has anybody experiences on VSTA regarding the possibilities
to read geometrical information of a selected part or body

How can you read geometrical informations (faces, vertices, nodes):
e.g. a box has 6 faces, it has ... nodes at X, Y, Z ...

I'm using this code to get these informations. Perhaps there is a easier way to do that.



Station station = Project.ActiveProject as Station;

if (station == null)
{
    Logger.AddMessage(new LogMessage("Station = null..."));
    return;
}

ProjectObject selObject = Project.ActiveProject.Selection.SingleSelectedObject as ProjectObject;
if (selObject == null)
{
    Logger.AddMessage(new LogMessage("Nothing selected..."));
    return;
}

Logger.AddMessage(new LogMessage("selected object: " + selObject.Name + " - " + selObject.Attributes.Count));

Part selPart = selObject as Part;

BodyCollection selBodiesC = selPart.Bodies;
Body selBody = selPart.Bodies[0];
Logger.AddMessage(new LogMessage("Number of bodies in selection :" + selBodiesC.Count));

ShellCollection shellC = selBody.Shells;
Logger.AddMessage(new LogMessage("Number of shells:" + shellC.Count));

Shell selShell = shellC[0];
FaceCollection faceC = selShell.Faces;
Logger.AddMessage(new LogMessage("Number of faces:" + faceC.Count));


foreach (Face f in faceC)
{

    LoopCollection faceLoopC = f.Loops;
    Logger.AddMessage(new LogMessage("Number of loops:" + faceLoopC.Count));
    Logger.AddMessage(new LogMessage("Face Color:" + f.Color.ToString()));

    foreach (Loop l in faceLoopC)
    {
        CoedgeCollection coedgeC = l.Coedges;
        Logger.AddMessage(new LogMessage("Number of coedges:" + coedgeC.Count));

        foreach (Coedge cEdge in coedgeC)
        {
             Vertex v0 = cEdge.StartVertex;
             Vertex v1 = cEdge.EndVertex;
             Logger.AddMessage(new LogMessage("Vertices: " + cEdge.StartVertex.Position.ToString() + " / " + cEdge.EndVertex.Position.ToString()));

        }//for coedges
    }//for loops
}//for faces
