Summary

Wish to have a method to calculate the outer boundary of some entities

Solution

In version 11.1.3 we have implemented and exported two methods in the commandAction of the Document like below

summary> Calculates the outer boundary of a given selection and a point inside the closed area.
param name="SelSet">A selection of vdFigures (see object) or "USER"/null so the user can pick entities from the screen.
param name="Point">A point in WCS inside the closed area that needs to be calculated.
returns>Returns a collection of Vertexes which represent the inner boundary of the passed entities that also includes the passed point.
public Vertexes Find_InBoundCurve(object SelSet, object Point)

summary> Calculates the outer boundary of a given selection.
param name="SelSet">A selection of vdFigures (see object) or "USER"/null so the user can pick entities from the screen.
returns>Returns a collection of Vertexes which represent the outer boundary of the passed entities.
public Vertexes Find_OutBoundCurve(object SelSet)

Some entities that we want to calculate the outer boundary (lines , arcs , polyline with bulges)	Outer Boundary

Some entities that we want to calculate the inner boundary (lines , arcs , polyline with bulges)	Inner Boundary

In SimpleCAD application you can find these methods in the commandline by searching commands : FindInBoundCurve , FindOutBoundCurve



Or in the menu under Modify-> Boundary

C# Code

Vertexes verts = doc.CommandAction.FindOutBoundCurve(null);
if (verts != null && verts.Count > 0)
{
    //Create a thick red polyline to see the result
    VectorDraw.Professional.vdFigures.vdPolyline result = new vdPolyline(doc);
    result.PenColor.ColorIndex = 0;
    result.LineWeight = VdConstLineWeight.LW_158;
    result.VertexList = new Vertexes(verts);
    doc.Model.Entities.AddItem(result);
    doc.Redraw(true);
}
