Different softwares use different axis orientations. That is quite a common thing to occur when a model moves between various 3d software packages. CAD Exchanger uses a right-handed coordinate system.
CAD Exchanger Lab offers the axis orientation setup, but only for these three formats: Collada, FBX, gLTF.
In order to resolve the problem of rotation after conversion, a model can be reoriented in the software it's coming from (some of them allow specifying the "up" direction), or to apply the transformation to a model using the CAD Exchanger SDK.
