What is DisplayDCS?

[Olhado_]

I have searched the Internet for any possible combination of AutoCAD DisplayDCS and I have also searched the help. However, there does not seem to be any good site that explains what this coordinate system is. It is located in an option for "TranslateCoordinates". I am pretty sure DCS stands for Display Coordinate System; but how is it determined?

 

It has something to do with the plot window in model space and I can imagine acPaperSpaceDCS must be the coordinates a viewport looks at in Model Space.

 

However, I am interested in DisplayDCS since I am trying to print a window in Model Space using the following code.

 

With Application.ActiveDocument.ModelSpace.layout 
       .ConfigName = strPrinter
       .StyleSheet = strStyleSheet
       .CenterPlot = True
       .StandardScale = ac1_1
       .ScaleLineweights = True
       .SetWindowToPlot dblLowerLeft, dblUpperRight
       .GetWindowToPlot dblLowerLeft, dblUpperRight
       .PlotType = acWindow
       .CanonicalMediaName = strPaperSize
       .RefreshPlotDeviceInfo
   End With

 

The variables in this code are correct; but after some coding and using the TranslateCoordinates I realize the SetWindowToPlot & GetWindowToPlot are printing in DCS. I tried to move the graphiics into this area, only to find out that the DisplayDCS has also moved.

 

So, is there anyone here who can help me understand the DisplayDCS coordinate system?

 

Thanks and sorry for this rant there has been a lot of "blood on the wall" trying to get to the bottom of this.
