Setting layers
DXF files usually contain several layers. The designer uses these
layers to create groups of various types of elements, e.g. the
actual workpiece contour, dimensions, auxiliary and design lines,
shadings, and texts.
So that little unnecessary information appears on the screen
during selection of the contours, you can hide all excessive layers
contained in the DXF file.
The DXF file to be processed must contain at least
one layer. Elements not assigned to a layer are
automatically moved by the TNC to the anonymous
layer.
You can even select a contour if the designer has
saved it on different layers.
Select the mode for the layer settings: In the List
View window the TNC shows all layers contained
in the active DXF file
