My model rotated after conversion. Why it happens?
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.
Why can't my model be processed?
The problem may stem either from CAD Exchanger or from the file you want to convert, but we won't be able to figure it out without reproducing the difficulties you're having, so please share your model for us to look into via this contact form. It ...
Can I edit my model in CAD Exchanger Lab?
CAD Exchanger Lab is only intended to be a viewer and converter. Although transformation and colors of the model’s elements can be changed with its help, editing their geometry will require the CAD Exchanger SDK.
How do I export only the needed parts instead of the whole model?
You can export only the elements you want by simply deselecting those you don't in the Scene graph (accessible through the "Structure" button at the top). Doing so will exclude them from the exported model. See partial export for more details.
How to retrieve the color of a point (in a BRep model)
1. Get the ModelData_BRepRepresentation of a part; 2. Get a list of all the Bodies that belong to this Part: ModelData_BodyList aBodyList = theBRep.Get(); 3. Use Appearance(aBody) method of the ModelData_BRepRepresentation object to retrieve ...
Model size limit
There isn't any file size limit in CAD Exchanger Lab. Still technically there can be a relative size limit depending on the PC`s hardware capabilities.
