Tip: How about adding zsphere in zmodeler to create topology ?! For example, by selecting the ZsphereTopology option in Zmodeler, and clicking the mesh, it would create a topology Zsphere, automatically enabling topology mode, and creating a new subtool. Can you do this with Zscript or add in an update? It would also be useful if you have the “snapQuad” option for Zsphere to interpret that we want to do a quad, and so it already creates more or less on the previous Zsphere line in a more automatic quad to do.
