Setting layers
CAD 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.
Hiding unneeded layers makes the graphics easier to read and
facilitates the extraction of the required information.
Operating notes:
The CAD file to be processed must contain at
least one layer. Elements not assigned to a layer
are automatically moved by the control to the
anonymous layer.
You can even select a contour if the designer has
saved the lines on different layers.
