If your delimited rectangle is a polyline then you can use it for the selection. That makes sure that you cover always the same window area, the "Print current view" has then the same size and the same scale. That makes your prints exactly proportioned to the printouts of other windows.Doriano wrote: ↑Thu Feb 11, 2021 4:47 pm...This is due to the fact that it is not possible to select exactly the entire window (which I always delimit in the standard A4 or 3/2/1/0 format) as the edges of the window are not "hoocked". And this means that the various selections are never the same and in the print sheet (A4 / 3/2/1/0) the elements drawn in turn are never exactly proportioned to the printouts of other windows.
Note: In my sample drawing the delimited rectangles are on their own layer with a disabled "Plottable" option.
Which QCAD version you are using?
