228  Programming: Data Transfer from DXF Files
7.1 Processing DXF Files (Software Option)
Selecting and storing machining positions
Three possibilities are available in the pattern generator for defining 
machining positions:
 Individual selection:
You select the desired machining position through individual mouse 
clicks (see “Individual selection” on page 229)
 Quick selection of hole positions in an area defined by the mouse:
By dragging the mouse to define an area, you can select all the hole 
positions within it (see “Quick selection of hole positions in an area 
defined by the mouse” on page 230)
 Quick selection of hole positions by entering a diameter:
By entering a hole diameter, you can select all hole positions with 
that diameter in the DXF file (see “Quick selection of hole positions 
by entering a diameter” on page 231)
You must use the touchpad on the TNC keyboard or a 
mouse attached via the USB port in order to select a 
machining position.
If the positions to be selected are very close to one 
another, use the zoom function.
If required, configure the basic settings so that the TNC 
shows the tool paths (see “Basic settings” on page 220).
