SetPlotWindowArea() got an offset

Anonymous — Sat, 21 May 2016 08:58:40 GMT

Hello, Everyone! I am trying to batch plot blocks by using c#.

The problem is in some dwg files the plot window area got an offset, but in some files the program runs quite well. The offset looks like this:

Here is part of the code:

// get extents of the block
Point2d ptMin = block.GeometricExtents.MinPoint.Convert2d(new Plane());
Point2d ptMax = block.GeometricExtents.MaxPoint.Convert2d(new Plane());
Extents2d window = new Extents2d(ptMin, ptMax);
// set plot window
psv.SetPlotWindowArea(ps, window);
psv.SetPlotType(ps, Autodesk.AutoCAD.DatabaseServices.PlotType.Window);
psv.SetPlotCentered(ps, true);
psv.SetStdScaleType(ps, StdScaleType.ScaleToFit);

In debugging, I can see the value of ptMin and ptMax is right, and the value in PlotInfo is also right, so I am really confused about it. By the way, I have change the UCS to WCS too.

Thanks for reply!

Check the TARGET variable, the ones that have the offset probably have a TARGET that is not 0,0,0.

Yes, it is the TARGET variable that causes the offset.

I found this post online: Plot or preview shows incorrect area of drawing when plotting limits

But how to change it by code?

Thank you for reply so soon!

You have translate coordinates from WCS to DCS: Plot To Window Extents Using VBA

With help of Autodesk.AutoCAD.Internal.Utils.UcsToDisplay(Point3d ucsPoint, bool bPaperSpace) you can translate UCS to DCS

In order to translate WCS to UCS you can use invert matrix Editor.CurrentUserCoordinateSystem
