I am using the trial version of Aspose.CAD to convert a dwg file to pdf. It works quite easy and fast but there are two big issues with the pdf file.
First of all: hatches are flipped. Every hatch in the drawing seems to be mirrored vertically.
Second issue: German chars like ä, ö and ü are broken. The dots are missplaced and often printed above the next char or way to much above.
Everything seems to be fine within TrueView and BricsCad, so I guess it is not an error of the dwg file.
