3. If necessary, use a scale factor to enlarge or reduce the appearance size of the map. Then
use the values in X and Y to shift the scaled map to the desired position. For details, see
Scaling a vector graphic below.
4. Click the colored button in the front of the edit field and select a color for the DXF-map
from a Color dialog box. The color will be assigned to a DXF-graphics entity, if the
entity's color is not defined in the DXF file. A line map will always use the selected color.
5. Check the check box next to the edit field. The map will be displayed only when the box
is checked.

X and Y should be 0 and Scale should be 1, if a DXF file is generated by PMWIN or
PMPATH. Because of different length units, DXF files created by some drawing or CAD
software may not be imported into PMWIN without modifying the scale factor and the X,
Y values. If these values are incorrect, a DXF-map will be displayed too small, too large or
outside the worksheet. If this happens, use the Environment options dialog box to define
a very large worksheet ensuring that the map can be displayed within the worksheet. Then,
you can check the units on the imported map by moving the mouse around the map and
looking at the X and Y coordinates displayed in the status bar. Choose two points that are
a known distance apart and check their distance with the status bar. If the distance is
incorrect, compute a scale factor and import the map again. Once you have the correct scale
factor, you may shift the scaled DXF-map to the desired position by using X and Y. Fig.
3.70 uses a triangle as an example to show the use of X, Y and the scale factor.
