Scaling

How do you scale a part of an object so that it doesn’t affect the rest of it? Thanks.

I’m not sure what do you mean.

Try to scale along one or two axis.

S then X/Y/Z key

or with two axis S then Shift+axis_you_don’t_wan_to_scale_with (S, Shift+Z - scale along X and Y)

Hope it weill help ya.

In edit mode, select the vertices you want to scale. Then press S and they will scale, while the other will stay. The will scale relative to the point you have specified in the header (object center, midpoint, cursor, etc).
