When I mirror objects in Sketchup and I then import them into my Lychee for 3D printing, it turns out the mirror I’ve done in Sketchup appears to also have reversed the faces of any objects I’ve mirrored, which is a real pain as I need to manually go and reverse them all, which kinda defeats the point of mirroring as an easy way of not having to draw it. Is there a solution for this other than to manually reverse the affected surfaces (ironically, they show normal in Sketchup so I have to actually make them inverted / blue, to get round the issue).
Go to the extension warehouse and get the STL exporter by the Sketchup team.
It adds an extra Export option to the file menu that will export your stl’s correctly.
Thanks very much!!!
