Selecting a Single Line
Choosing a line upon which you want to apply a command is called "selecting". When you select a line it changes color so that it stands out from the other lines. When you select a line some symbols, called "handles", are displayed to indicate what you can do with the line. You can select any line in your design. For example you might need to select a line to stretch it.
Selecting Multiple Lines
You can select more than one line at a time.
You can also add or remove lines from those already selected. Any action you perform on the selection affects all selected lines. For example you might need to select six circles representing holes and change their diameters.
Selecting connected lines
To select all lines connected to a particular line:
Selecting Overlapping Lines
When your design includes lines positioned exactly on top of each other and you need to select a line that lies at the bottom, select one of the lines, nudge it left or right, select the line you need, and later nudge the original line back into position.
Selecting lines of particular machine
Your design may include lines for different machines. You can select all lines assigned to one particular machine. For example you might need to select all Thread lines to remove them from the drawing.
