A question on importing meshes.

Hello, i am a new member and i have stumbled into blender. I use DesignCad, a CAD-based 3d modeling software. The file format i import to blender is the .dxf enxtension (which i am very happy to say that blender shakes hands with). the question i want to ask is does blender have a recalculate mesh or a balance mesh command? to explain, does blender have a command that can take a polygon mesh made from an outside program and reorganize the imported mesh’s vertices and faces.
thanks for your help

hi,
I’m not sure exactly what you mean by “reorganize” verts and faces.
could you perhaps elaborate on what you are trying to do?
I’m not familiar with CAD terminology so if this is common thing I apologize.
