Layer settings
As a rule, DXF files contain multiple layers, with which the designer
organizes the drawing. The designer uses the layers to create groups of
various types of elements, such as the actual workpiece contour,
dimensions, auxiliary and design lines, shadings, and texts.
So that as little unnecessary information as possible appears on the
screen during selection of the contours, you can hide all excessive layers
contained in the DXF file.
8 If it has not already been activated, select the mode for the
layer settings. In the left window the TNC shows all layers
contained in the active DXF file.
8 To hide a layer, select the layer with the left mouse button,
and click its checkbox to hide it.
8 To show a layer, select the layer with the left mouse button,
and click its checkbox again to show it.
The DXF file to be processed must contain at least one
layer.
You can even select a contour if the designer has saved it
on different layers.
