Hello, Here's a convex, closed model I've made for Geometry Level of Detail (LOD). It's just a quick example of a problem I've encountered. This model was created by me and it can be publicly accessed here. {F3015794} I'm using `Blender 3.5.1` with `Enfusion tools` installed. My model successfully passes the `Non-Convex` check. {F3015791} However, when I import it to `Object Builder` (OB), it fails the `Find Non-Convexities` check. {F3015783} Applying `Component convex hull` ensures all components are convex but it also creates holes in the geometry, which leads to a failed `Find Non-Closed` check. Alternatively, it can completely distort the geometry, as in this instance, even though it was convex and closed before applying the `Component convex hull`. {F3015785} When I export it from `Blender` as an .obj file, the situation gets even worse. OB identifies all (or nearly all) vertices as parts of the non-convex geometry. It's worth mentioning that this is a simplified version of an issue I've been dealing with for a long time. When I'm creating Geometry LOD for more complex objects like buildings, there are many more areas that OB marks as non-convex. {F3015780} Does dev-team have any suggestions on how to import to OB without losing the convexity of the model? I'm getting tired of manually recreating the problematic faces in OB, especially when a model has tens of them.

For example we have a model with 26 points found as parts of non-convex geometry. {F3015908} Scaling up model 10 times by using `Scale` tool in OB results in 59 points marked as non-convex. {F3015911} Does dev-team have any suggestions on how to import to OB without losing the convexity of the model?
