3D models not visible in the MCAD tool after exporting from the PCB editor tool

Dear community,

I had created a PCB board and mapped all the step models with 3D models and i can see all the 3D models in the 3D canvas window, but when i export the step file of the PCB board and import to MCAD tool, i am seeing only plane board without any 3D models, i have provided the step path in the User preference paths.
