STL files for case had wrong scaling #5

Open jvoigts opened 10 years ago

jvoigts commented 10 years ago

The solidworks stl export seems to have a bug where the scale of exported models is off by a factor of ~10. I pulled the STL files for now (b67f11bde5f82b34f1b45ca4ad48b5306b4bbc50). Can someone else try replicating this, maybe it's specific to my version of solidworks. We have the 2013 version here.

In the meantime, use the .sldprt or .igs files.

Is this not just a mm/cm conversion issue? SolidWorks always exports STL files in mm.

jvoigts commented 10 years ago

Don't think so - at least changing units in the export doesnt fix it. I'll try re-setting the units in the base sldprt file instead - maybe the export function just blindly assumes mm and the micron/mm/cm setting in solidworks outputs cm or something like that?

How are you assessing whether it's correct or not?

jvoigts commented 10 years ago

i'm just opening the STLs in either solidworks or in the makerbot replicator software, getting the same issue in both right now.

jvoigts commented 10 years ago

ok, Eric just checked another vendor and the dimensions came out ok, so it seems like there's something odd in the header of the stl that sometimes, but not always gives a scaling error. I guess i'll add the stl files back in with a very visible warning.
