Facing Problem while converting RVM to FBX using Aspose 3D

Hi, I’m using Aspose.3D for Java 23.10 and I faced some problem while converting RVM file to FBX.
Almost of all RVM files are convert very well but some files get exception and couldn’t be convert it.

Here is the exception log.
Exception in thread “main” com.aspose.threed.ExportException: Cannot assign field “_objectId” because the return value of “com.aspose.threed.IMeshConvertible.toMesh()” is null

To solve this problem, I tried debugging and found out the reason for exception.
In API References, “toMesh()” at Cylinder class returns the Mesh object. I found that if the value of “radiusTop” and “radiusBottom” are not greater than 0.0, it return NULL.

Among the RVM files I have, the radiusTop and radiusBottom of a specific cylinder seem to be 0.0, and this seems to be why the exception occurs.

So can I request a hotfix to allow the radius of the cylinder to contain 0 to resolve this issue?
If it’s difficult, please tell me another way.
