can I ask why you are using the apt get install command for openscad? the repository version 2015.03-2 is > 3 years old. why don't you try the latest openscad appimage? and see if that works for you? 73, Jerry -- Extra Ham Operator: K7AZJ Registered Linux User: 275424 Raspberry Pi and 3D designer *The most exciting phrase to hear in science - the one that heralds new discoveries - is not "Eureka!" but "That's funny...".*- Isaac.

for the sake of others that come here after you... you may want to make a different thread Look for as many of the development packages as you can through your package manager, you should only need to compile and install a few libs from source... the openSCAD build process is fairly painless once you have all the dependencies installed...

Ok, I will try again and report back in a week or two on another thread eg OpenCSG upgrade or some such thing.

I've tried updating the AppImage builds so they are using the newest OpenCSG. Both should report OpenCSG 1.4.2 in the library info window. Release version 2015.03-3: https://download.opensuse.org/repositories/home:/t-paul/AppImage/OpenSCAD-Release-latest-x86_64.AppImage Dev Snapshot: https://download.opensuse.org/repositories/home:/t-paul/AppImage/OpenSCAD-Nightly-latest-x86_64.AppImage ciao, Torsten.

Thank you Torsten, that is very helpful. I will be home in about 5days and will report back after that.

Cheers Torsten, that worked perfectly for me. Much Appreciated. Library correctly reported as below. You have made it so simple!!! Errors no longer jeopardize the F5 preview mode. Are these AppImage versions clearly advertised on the OpenSCAD site? I did not find them.

I did not find them. > For small values of clearly, yes. :-) As of now only the Dev-Snapshot for Intel/64bit is linked in the download section. This is still pretty new and not too well tested on various distributions and we also rely on OBS (OpenSUSE build service) to build those. There's still some changes going on there which make it a bit unstable, e.g. the ARM builds are currently not working, I don't know why yet. ciao, Torsten.
