I just downloaded the exportVCL example application. I ran it, exported the form image to a DXF and viewed the resulting DXF in a couple of different viewers. Though there are differences in the handling of shapes, they all agree that the position of the various shapes is very different to what is seen in the original. For example, in the application, you see from top to bottom, 3 boxes, line (near the top of the boxes), small text, large text. In the DXF viewers you see Large Text, Small text, 3 boxes, line (near the bottom of the boxes). It seems that part of the Y position is inverted. Also, the boxes never have line thickness or fill as displayed in the app (though this may just be a limitation of the 3 viewers I tested).
Is this just an error in the app or a limitation of the VCL?
