Finding solid face and edge

[NachitoMax]

Hi

Been trying to this, can't figure it out... I have a bunch of solid parts. Let's say they are 600 x 600 x 20mm thick. I need to be able to highlight all of the edges only (600 x 20) and ignore the largest faces. I'm not talking about the edge lines, I'm talking about the long thin faces. Think of an mdf panel and I want edging on them.

Can this be done? I can find the largest face but not all of the thin faces .

I can use vba and .net.


Thanks in advance

Hi, Nige,

If I understand you, you want to highlight four faces (600x20), but not to highlight two faces (600x600).

Did you tried with Faces object in SufaceBodies under PartDocumentDescription?

Best regards,

Nedeljko.

Hi

The other way. I want to highlight the 2 600 x 600 faces

Thanks

Attached is some code to demonstrate how you might go about it. (Hasn't been tested.)

    public class ShowFaces
    {
        //Compare Face by area
        public static int CompareByArea(Face face1, Face face2)
        {
            double area1 = face1.Evaluator.Area;
            double area2 = face2.Evaluator.Area;
 
            if (area1 < area2)
            {
                return -1;
            }
            else if (area1 > area2)
            {
                return 1;
            }
            else
            {
                return 0;
            }
        }
 
        //Get Panel Surfaces - Returns list of Panels
        public static ObjectCollection GetPanelSurfaces(SurfaceBody body)
        {
            Inventor.Application _appInventor = (Inventor.Application)body.Application;
            Faces faces = body.Faces;
            List<Face> lstFaces = new List<Face>((IEnumerable<Face>)faces);
            lstFaces.Sort(CompareByArea);
            ObjectCollection objCol = _appInventor.TransientObjects.CreateObjectCollection();
            objCol.Add(lstFaces[0]);
            objCol.Add(lstFaces[1]);
            return objCol;
        }
 
        //Highlight entities
        public static void HighlightEntities(PartDocument ivDoc, ObjectCollection objCol)
        {
            if ((objCol != null) && (objCol.Count > 0))
            {
                Inventor.Application _appInventor = (Application)ivDoc.Parent;
                HighlightSet hs = ivDoc.CreateHighlightSet();
                Inventor.Color oRed = _appInventor.TransientObjects.CreateColor(255, 0, 0);
                oRed.Opacity = 0.8;
                foreach (object obj in objCol)
                {
                    hs.AddItem(obj);
                }
            }
        }
 
        //Highlight the largest panels.
        public static void HighlightLargePanels(PartDocument pDoc)
        {
            SurfaceBodies sbs = pDoc.ComponentDefinition.SurfaceBodies;
            foreach (SurfaceBody sb in sbs)
            {
                HighlightEntities(pDoc, GetPanelSurfaces(sb));
            }
        }
    }

Basically get the two largets surfaces on a surface body. Add them to a HighlightSet.
