Currently, C3 already supports simple 3D views, but from 2D top-down. You have to press the space bar, drag the layout area, and use the scroll wheel to preview the screen at a specific Angle.It's not very convenient.

So, if can add a shortcut key, like pressing 'R in the editor that allows you to rotate layout.(Just preview in the editor)

Mouse left and right, can rotate layout.

Mouse Up and right, can change Vanishing point.

Note that this is just a preview in the editor. Therefore, in the rotation mode, a prompt bar will appear at the top of the editor to indicate the current rotation Angle and the parameter of the vanishing point. Then there is a hyperlink button to reset. Or double-click on Rotate it automatically goes to 0°
