¨ You can specify the units you want to work in: millimeters (mm), centimeters (cm), meters (m), inches (fraction), numerical inches, pixels (screen units), or none (virtual units).
¨ You can specify the number of places after the decimal point to be displayed.
¨ You can also specify the units of angular values (degrees or radians).
¨ You can work in Absolute or Relative mode.
In absolute mode, coordinates are measured relative to the origin, which is by default the center of the workbench.
In relative mode, coordinates are measured relative to the last point created. (You can specify a different origin for Absolute mode).
¨ You can change the origin of the absolute coordinate system to somewhere other than the center of the table (if you selected this mode).
- Click on the “Set it” button,
- And specify an existing point, using the Bullseye cursor, as the origin of the absolute coordinate system.
Or:
- Click on “Set it”,
- And enter numerical values in the corresponding fields of the dialog box.
¨ Finally, you can specify a working scale:
- Enter the percentage of enlargement or reduction in the dialog box (100% is the default value).
- Or select the sub-menu and choose a size from the list of choices.
- Or click on the “Set it” button then select two existing points. The distance between those two points will be the current work unit.
