1. The contour direction
is determined by the defined start point •→
and the remaining contour selection. When the contour is traced,
an attempt is made to automatically select as much of the contour
as possible.
2. Selection in the event of conflict
If the automatic contour trace function cannot determine a
following element clearly, interactive mode is activated. You will be
prompted to identify the next element in the contour.
3. Full circle as contour
The contour trace can integrate a full circle in both directions.
Set the contour end point
Element Center
Element End Point
Mouse Position
Current Position
4. Set the end point
You can set and save the end point at any contour trace element
of your choice.
Further notes
• Full circles can be saved as a contour or as drill points.
• You can cancel the contour trace either via the keyboard with the
"Esc" key or via the right mouse button.
Set the contour label
Before the contour is traced, you can set labels by entering start and
end labels.
The CAD Reader switches to interactive mode if you specify a label
which has already been assigned, i.e.
• when the trace is performed on contours that are already selected
• when the contour is attached to files which already contain the
label.
