Hatches could often be the cause of slow rendering (or in this case large PDF exports). One of the hatches in the marked area is a rectangle shaped hatch of about 400x300 units with pattern HOUND and a scale factor of 0.05. This could easily take several seconds to render. If the factor would be ev...

I've had a look again and found the culprit. There's a simple and logical explanation and fix after all: - The rectangle that seems to be solid filled contains really four extremely dense hatch patterns on top of each other (patterns NET and HOUND) - These hatch patterns cause the large file size s...

Hello, got attached pdf files with Debian GNU/Linux (testing) and the CUPS pdf driver (printer-driver-cups-pdf, version 2.6.1-20) and QCAD 3.9.2.0 / Qt 4.8.6. Regards Stephan :lol: Fantastic Stephan! So there is hope for me to stick with QCAD on linux. Did you modify the original drawing at all, or...

After looking for .dxf file viewers I came across LibreCAD, and it could view my QCAD .dxf file nicely and export as PDF with a file size of just 1.1 MB, which is much better than QCAD's 12.6MB. LibreCAD uses Qt too, so Qt alone can't be the cause of QCAD's PDF bloat on linux. :?: So there are worka...

PDF export is handled between the Qt tool kit which QCAD is based on and the operating system's PDF driver . Unfortunately, QCAD is too far away from all of that to be able to influence the file size. I've tested this also with the latest Qt version 5.4.1 (on Mac OS X) and the file size is still ar...

OK, so if QT is the problem, would this also explain why using the Print option and selecting the "PDF printer" gives the same bloated PDF?

I have a fairly small drawing of 333 KB in size (attached), but when I export to PDF, the PDF size is 12.6 MB! e_surprised This is even after I have turned off the auxilary layer and removed some peripheral details. I tried the QCAD export, and well as printing to the linux PDF printer, and both gav...
