    End Points Section
    In This Topic

    The end-points section defines the start and end points of a 1D shape. It is an optional section and is represented by an instance of the NEndPointsSection class. This section is created and accessed by the EndPointsSection property:

    C#
    Copy Code
    // create the end points section and modify the start and end points
    sheet.EndPointsSection = new NEndPointsSection();
    sheet.EndPointsSection.StartX.Value = 130;
    sheet.EndPointsSection.StartY.Value = 210;
    sheet.EndPointsSection.EndX.Value = 170;
    sheet.EndPointsSection.EndY.Value = 160;
    
    Visual Basic
    Copy Code
    ' create the end points section and modify the start and end points
    sheet.EndPointsSection = New NEndPointsSection()
    sheet.EndPointsSection.StartX.Value = 130
    sheet.EndPointsSection.StartY.Value = 210
    sheet.EndPointsSection.EndX.Value = 170
    sheet.EndPointsSection.EndY.Value = 160
    

    The end-points section contains the following set of named cells:

    Cell Name Cell Type Description Notes
    StartX Single Controls the X coordinate of the shape start point. Accessible from the StartX property. Usually a constant
    StartY Single Controls the Y coordinate of the shape start point. Accessible from the StartY property. Usually a constant
    EndX Single Controls the X coordinate of the shape end point. Accessible from the EndX property. Usually a constant
    EndY Single Controls the Y coordinate of the shape end point. Accessible from the EndY property.  Usually a constant

    Usually when you create a 1D shape the transform section of the sheet is also modified to represent the following: 
    1. The Width is the distance between the start and end points

    2. The Angle is the angle between the (start point, end point) vector and the X axis.

    3. The Local Pin is the middle of the local coordinate system

    4. The Pin is the middle of the (start point, end point) line segment.

    5. The Height is a user defined constant

    The following code example illustrates a typical transform section for a 1D shape:

    C#
    Copy Code
    sheet.TransformSection.Width.Formula = "SQRT((EndX-StartX)^2+(EndY-StartY)^2)";
    sheet.TransformSection.Height.Value = 193;
    sheet.TransformSection.Angle.Formula = "ATAN2(EndY-StartY,EndX-StartX)";
    sheet.TransformSection.PinX.Formula = "(StartX+EndX)/2";
    sheet.TransformSection.PinY.Formula = "(StartY+EndY)/2";
    sheet.TransformSection.LocPinX.Formula = "Width*0.5";
    sheet.TransformSection.LocPinY.Formula = "Height*0.5";
    
    Visual Basic
    Copy Code
    sheet.TransformSection.Width.Formula = "SQRT((EndX-StartX)^2+(EndY-StartY)^2)"
    sheet.TransformSection.Height.Value = 193
    sheet.TransformSection.Angle.Formula = "ATAN2(EndY-StartY,EndX-StartX)"
    sheet.TransformSection.PinX.Formula = "(StartX+EndX)/2"
    sheet.TransformSection.PinY.Formula = "(StartY+EndY)/2"
    sheet.TransformSection.LocPinX.Formula = "Width*0.5"
    sheet.TransformSection.LocPinY.Formula = "Height*0.5"
