I love to work with QCAD. It's really a good program and it's getting better all the time. Recently I came across another exciting piece of software: Z88Aurora
Z88Aurora is a free finite element software package for static calculation in mechanical engineering. Beside linear static analysis you can use it for large displacement analysis, stady state thermal analysis and natural frequency analysis.
AND it can do 2D, too! Sounds great, doesn't it? So I fired up my QCAD installation and quickly designed a simple 2D-drawing and saved it as DXF R2010.
Then I tried to import it in Z88Aurora and ... failed. Oh dear, I was disappointed. It seems, that the DXF from QCAD is not compatible with the Autocad-DXF that Z88Aurora expects.
Please make it work! That would be such a great thing to be able to use QCAD as a source for 2D-models.
PS: I use the Linux-version of QCAD and Z88Aurora.
