Three: Modifying the extrusion band

Once the side lobe is in place, we can start to shape the extruded surface below, so that they look like they belong together. To create tighter curves we need more rows of CVs. This is not a problem, we can insert extra geometry into the surface without changing its shape using the Insert Isoparm command.

Four vertical Isoparms are selected on the surface (the yellow lines) then the Insert command is used to add the extra columns of CVs. These don't appear where the Isoparms were though, but it's simple to select and move them where you need them. Here we've added a crease that continues a line from the lobe.

Thouen't used it much, we have been modelling with Construction History active. For the next step we'll remove the History and save the head as a new file. This way we can always come back to the History-enabled version if we need it.
