Hi,

I’m experiencing this when trying to shell my object (0,2 mm). Shelling will fail on larger values. The object is about 10mm square, 3,5mm high. Looks like something going wrong in that left point, so I thought I’d share.

Unfortunately this is a known issue, and will be fixed with this release: [http://discourse.shapr3d.com/t/something-big-is-coming-and-we-cant-wait-to-share-it-with-you/](http://discourse.shapr3d.com/t/something-big-is-coming-and-we-cant-wait-to-share-it-with-you/)
