2-D Matrix Transformations

Post by Christof » Thu Sep 19, 2013 10:30 am

Is it possible to apply matrix transformations to drawings in QCAD 3, without writing a script for it? At the moment I'm doing it in Inkscape (Object -> Transform ... -> Matrix) and importing the results into QCAD using SVG files. Would be more productive and accurate to do it natively in QCAD.

Thanks.

That's currently not possible, but I should be able to whip that up with a very short script.

In any case, I've added a feature request at:
http://www.qcad.org/bugtracker/index.ph ... ask_id=920

This has a good chance to get implemented for the next version as the effort would be very small.

I've implemented matrix transformations for the next release. Here's an example for a shear matrix

QCAD 3.3.2 is available now with the new matrix transformation tool.

Christof: I'd be interested in hearing what you are using this tool for, if you don't mind. Thanks.
