Two Tips For Move And Rotate Tools
This covers some tool settings that I found useful to help the modeling process.
Move tool Mirror
The reflection option for the move tool allows you to select a vertex on one side of the model and, on the opposite side, the vertex with a similar position will be selected and moved the same way.
Now just select the axis that you want to mirror on. The half square on the move manipulator signifies the axis.
Also, the tolerance attribute sets how much Maya will tolerate a difference in selecting the opposite side's vertices. A larger tolerance will allow for a larger difference between the two sides.
Rotate Tool Snap To Degrees
Most of the time when I use the rotate tool, I use 45 or 90 degree angles. Since it's hard to eyeball, I end up opening the channel box or attributes editor to make sure it's dead-on. Here's a way around that.
Check snap rotate. Now set the step size to the amount of degrees you want the rotate tool to snap to. 45 works best for me.
Now when you rotate the object it will snap in 45 degree increments.
