Dear Experts,

Can some body help why the below AutoCAD .Net code is not working in progeCAD using IntelliAD API. Hence, the work around we have done using CrossingPolygon. But can some body know the reason why cEditor.SelectCrossingWindow( is not working.

public static SelectionSet GetSelectionSet(string layerName, string entType, Point3d pnt)
{
Point3d upperPnt = new Point3d(pnt.X + 0.05, pnt.Y + 0.05, pnt.Z);
Point3d lowerPnt = new Point3d(pnt.X - 0.05, pnt.Y - 0.05, pnt.Z);
Editor cEditor = Application.DocumentManager.MdiActiveDocument.Editor;
TypedValue tType = new TypedValue(0, entType);
TypedValue tValue = new TypedValue(8, layerName);
ZoomCentre(pnt, 0.05);
SelectionFilter sFilter = new SelectionFilter(new TypedValue[] { tType, tValue });
PromptSelectionResult pSelResuult = cEditor.SelectCrossingWindow(upperPnt, lowerPnt, sFilter);
return pSelResuult.Value;
}
static public ViewTableRecord ZoomCentre(Point3d centre, double magnification)
{
Document doc = Application.DocumentManager.MdiActiveDocument;
Editor pEd = doc.Editor;
Point2d centPt = new Point2d(centre.X, centre.Y);
ViewTableRecord pViewTabRec = new ViewTableRecord();
pViewTabRec.CenterPoint = centPt;
pViewTabRec.Height = magnification;
pViewTabRec.Width = magnification;
pEd.SetCurrentView(pViewTabRec);
return pViewTabRec;
}

Below Coverted the above method to Crossing Polygon:

public static SelectionSet GetSelectionSet(string layerName, string entType, Point3d pnt)
{
Point3d upperPnt = new Point3d(pnt.X + 0.1, pnt.Y + 0.1, pnt.Z);
Point3d lowerPnt = new Point3d(pnt.X - 0.1, pnt.Y - 0.1, pnt.Z);
Editor cEditor = Application.DocumentManager.MdiActiveDocument.Editor;
TypedValue tType = new TypedValue(0, entType);
TypedValue tValue = new TypedValue(8, layerName);
ZoomCentre(pnt, 0.001);
cEditor.Regen();
SelectionFilter sFilter = new SelectionFilter(new TypedValue[] { tType, tValue });
Point3dCollection polygonPoints = new Point3dCollection
{
lowerPnt,
new Point3d(upperPnt.X, lowerPnt.Y, lowerPnt.Z),
upperPnt,
new Point3d(lowerPnt.X, upperPnt.Y, lowerPnt.Z),
lowerPnt
};
PromptSelectionResult pSelResult = cEditor.SelectCrossingPolygon(polygonPoints, sFilter);
return pSelResult.Value;
}

Hi Srinivasa,
Not check but when you do SelectCrossingPolygon, the Point3dCollection cannot be duplicated and self-intersected.

Dear QuanNguyen,

Thank you for your suggestion. But the issue we were facing is with SelectCrossingWindow not with SelectCrossingPolygon. The same has been mentioned in code snippet shared earlier.

Thanks and Regards,

Hi Srinivasa,
It seems that we zoom in too near, all points need to be inside the "View Screen Size" (not in the boundary).

public static SelectionSet GetSelectionSet(string layerName, string entType, Point3d pnt)
{
Point3d upperPnt = new Point3d(pnt.X + 0.05, pnt.Y + 0.05, pnt.Z);
Point3d lowerPnt = new Point3d(pnt.X - 0.05, pnt.Y - 0.05, pnt.Z);
Editor cEditor = Application.DocumentManager.MdiActiveDocument.Editor;
TypedValue tType = new TypedValue(0, entType);
TypedValue tValue = new TypedValue(8, layerName);
ZoomCentre(pnt, 0.05 * 1.2 );
SelectionFilter sFilter = new SelectionFilter(new TypedValue[] { tType, tValue });
PromptSelectionResult pSelResuult = cEditor.SelectCrossingWindow(upperPnt, lowerPnt, sFilter);
return pSelResuult.Value;
}

Given that you stated using SelectCrossingPolygon as a workaround, it implies that, in your scenario, IntelligCAD's API manages polygon-based selections more consistently than bounding boxes based on point collection processingboxing random
