How to implement mixed render mode

Summary

I was just wondering if I could get a sample project or code snippet to achieve followings.

Mixed render mode while drawing figures;
1. Draw a vdPolyface with Wire3D render.
2. Draw ALL other figures with Shade/Hide/ShadeOn/Render modes render.

Solution

Try a code like :

private void Form1_Load(object sender, EventArgs e)
{
    vdFramedControl1.BaseControl.ActiveDocument.New();
    if (vdFramedControl1.BaseControl.ActiveDocument.CommandAction.CmdSphere(new gPoint(0, 0, 0), 3.0d, 6, 6)) 
    {
         vdFramedControl1.BaseControl.ActiveDocument.Model.Entities[vdFramedControl1.BaseControl.ActiveDocument.Model.Entities.Count - 1].Label = "WIRE3D"; // the sphere will be drawn as Wire3D
    }
    vdFramedControl1.BaseControl.ActiveDocument.CommandAction.CmdBox3d(new gPoint(5, 0, 0), 3.0d, 4.0d, 2.0d, 0.0d);
    vdFramedControl1.BaseControl.ActiveDocument.ZoomExtents();
    vdFramedControl1.BaseControl.ActiveDocument.FreezeEntityDrawEvents.Push(false);
    vdFramedControl1.BaseControl.ActiveDocument.GlobalRenderProperties.CustomRenderTypeName = "VectorDraw.Render.opengllist#VectorDraw.Professional.dll";
 
    vdFramedControl1.BaseControl.ActiveDocument.OnDrawFigure += new vdDocument.FigureDrawEventHandler(ActiveDocument_OnDrawFigure);
}
 
void ActiveDocument_OnDrawFigure(object sender, VectorDraw.Render.vdRender render, ref bool cancel)
{
    vdPolyface pface = sender as vdPolyface;
    if (pface != null)
    {
        if (pface.Label == "WIRE3D")// You can check here by Label/XProperty/Handle/Type/Layer etc
        {
            vdFramedControl1.BaseControl.ActiveDocument.FreezeEntityDrawEvents.Push(true);
            VectorDraw.Render.vdRender.Mode RMode = render.RenderMode;
            render.RenderMode = VectorDraw.Render.vdRender.Mode.Wire3d;
            pface.Draw(render);
            render.RenderMode = RMode;
            cancel = true;
            vdFramedControl1.BaseControl.ActiveDocument.FreezeEntityDrawEvents.Pop();
        }
    }
}
