Welding Meshes after perfoming tessellation .

Hi ,
I've using opencascade's BRepMesh_IncrementalMesh to perform meshing .
I then exported to glb and opened the file with blender . The file works really fine .
I then uploaded the file to babylon's sandbox and found out that since i exported just after tessellation , all the primitives are meshes and babylon draws every primitive everytime i move the camera resulting to a really big number of draw calls .
I found out that blender welds the node's primitives to one mesh by itself after uploading the glb file . I exported the blender render to glb and uploaded it to babylon's platform and found out that all the primitives are merged .
Is there a way to merge all the primitives to one mesh after tessellation ?
