Add lead wire

Figure: Add lead wire interface

Select to add the lead-in wires or lead-out wires, as well as the length and angle of the lead wire.

automatically set the inner and outer cutting properties of the graphics and automatically detect the validity of

the lead wires as needed.

Auto searching an appropriated angle is to automatically calculate the angle of the added lead wire

according to the graphic characteristics (from the tangent direction or vertical direction).

To check the lead-in and lead-out, you can set the safe distance of lead wires, and modify the qualified lead

wires (check the inference among the lead wires and the graph itself and other graphs)

Modify lead-in lead-out wires: Enter the modification status, use the left mouse key to drag the end point

of the lead wires to the desired position. (Status operations press the ESC key to exit)

Detect lead-in lead-out wires: set the lead wires safe interval in the pop-up window, if the lead wires

intersect the original primitives, it will be shortened automatically. The safe interval of the lead wires is

generally set to be relatively small, otherwise it will easily cause the failure of lead wires addition.

Modify starting point:

Click to modify the starting point icon

to enter the state of modifying starting point. Click the

mouse in the drawing interface. If the first click is outside the graph, and the second click is on the graph, add a

lead wire between the first click position and the second click position, and modify the starting point to the

second click position. If you click on the graph for the first time, the starting point is directly modified to this

position (the starting point of the non-closed graph cannot be modified). (Status operations press the ESC key to

exit)

Positioning setting:

Set the graphic reference point (the point marked by the green square) as a reference for various motions of

the graph (it is used when the floating coordinate system and the workpiece coordinate system are processing).

User can directly specify the 9 relative positions of the selected graphics as the reference points, or you can use
