Explode CAD model block to Brep

Hi Guys

My native 3D model was created from a CAD system (Creo). And I recently encounter an issue in which Grasshopper is unable to detect a CAD model as a Brep. Reason being, there is one level of exploding needed. The imported model exist as a Block object.

To solve this, I would use the Explode command to explode the model into a close-polysurface level. Then Grasshopper is able to detect it as a Brep.

Like to check with you guys if there any method to do this Explode block step all within Grasshopper?

Thanks in advance
