New thread. I've built libopencsg 1.4.2 from source and installed it. ldd /usr/bin/openscad-nightly | grep csg libopencsg.so.1 => /usr/local/lib/libopencsg.so.1 (0x00007fe3dde8f000) ll /usr/local/lib/libopencsg.so.1 /usr/local/lib/libopencsg.so.1 -> libopencsg.so.1.4.2* All looks good. But OpenSCAD still reports - OpenCSG version: OpenCSG 1.4.0 and my preview issue remains. Ideas?

do you have a packaged version of opencsg still installed? does LD_LIBRARY_PATH get checked before other lib paths ?? (I can't quite remember the order) you could try setting it to /usr/local/lib LD_LIBRARY_PATH=/usr/local/lib ./openscad On 17/07/17 16:57, Ian Oliver wrote: > New thread. > > I've built libopencsg 1.4.2 from source and installed it. > > ldd /usr/bin/openscad-nightly | grep csg > libopencsg.so.1 => /usr/local/lib/libopencsg.so.1 > (0x00007fe3dde8f000) > ll /usr/local/lib/libopencsg.so.1 > /usr/local/lib/libopencsg.so.1 -> libopencsg.so.1.4.2* > > All looks good. > > But OpenSCAD still reports - > > OpenCSG version: OpenCSG 1.4.0 > > and my preview issue remains. > > Ideas? > > > > _______________________________________________ > OpenSCAD mailing list > Discuss@lists.openscad.org > http://lists.openscad.org/mailman/listinfo/discuss_lists.openscad.org

As per comments at the bottom of this thread, setting Orthogonal fixes this for me. https://github.com/openscad/openscad/issues/1591 As it happens, I only need perspective to check accuracy of my model against picture of "real" things, and when doing the latter I'm usually not slicing, so this is close to a perfect solution.
