Zbrush | Measure angle with Transpose Tool

Is it confusing?

Let me explain.

Over here, I have a Polymesh Cylinder3D.

All the surfaces belong to one polygroup.

Let’s measure the angle difference of each of the sides.

Turn on gizmo by pressing W. Press Y to activate Transpose tool.

Click at the center and drag out to the first point to check the angle.

You can read the angle at the top left corner of the window.

Now let’s check the angle of the neighboring face.

Click and drag starting from the center.

Snap to the second point.

Next to the previous face.

Do the same to the third to be sure that the difference is 11 degrees.

Let me set the maximum angle to 11 degrees, which means I need to set the maximum angle

to 11 degrees at the Groups by normals slider,
