Hi, i'm trying to use slicer 5 plugin which is this one; https://sketchucation.com/plugin/781-tig_slicer
And for using this plugin i need a solid object. In spite of i'm using "solid inspector" for checking if it is solid or not, it's still not solid.However, solid inspector says everything is ok, objects is still manifold.
How can i convert it to solid and find out which part of the model i was mistaken.
