How do you extrude a face to a new polygon with PolyGroup Edit in v5.3?

I’d like to extrude this face to a new polygon, instead of by default having the new extrude stitched to the previous mesh. How can I achieve this result?

Hi Maxi, Welcome to the Fourms,

Good Question, I don’t think this is possible directly with the extrude tool.

Closest solution I can come up with is to do the extrude, then select the geometry with the Mesh → Tri Select tool. Use the ‘Separate’ function with Tri-Selection.

Then you can use the Model → PolyGroup Edit → Select 2 Edges → Fill Hole to close the holes if need be.

Additionally XForm → Edit Pivot to make a more sensical pivot with your newly separated geometry.
