Surface editing and transformation method of fine engraving machine

   The development of the engraving machine industry is changing with each passing day. From the ordinary engraving equipment, a carving machine capable of performing fine work has been derived. Key carving CNC sharing stone carving machine carved surface editing and transformation method:
   The way to control the control of vertices. “Manual movement” is more common, “proportional transformation” and “rotation transformation” are difficult to control, and the shape of the curved surface after editing is difficult to predict, so it is recommended to use it as little as possible.
(1) Manual movement: The selected control vertices move directly with the mouse to modify the coordinate components of the control vertices. During operation, click the left end of the color coordinate frame with the left mouse button, and hold down the left button.

Move the mouse and control the vertices to move as the mouse moves.
(2) Proportional transformation: scaling and selecting a plurality of selected control vertices in a specified direction with respect to a color coordinate frame origin. Click and hold the left mouse button while operating, and hold down the left button.

Move the mouse away from the origin of the color coordinate frame, and control the vertices to scale as the mouse moves. Note that multiple control vertices must be selected for "proportional transformation".

The point falls on the center of gravity of multiple control vertices.
(3) Rotation transformation: Rotate and transform the selected multiple control vertices around a specified axis. When operating, use the left mouse button to click on a selected control vertex, and hold down the left button to move

With the mouse, the control vertices will rotate as the mouse moves. Note that multiple control vertices must be selected for "rotation transformation", where the coordinate origin falls on the center of gravity of multiple control vertices.
