· 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.
· You can change the working scale:
· Enter a percentage of scaling in the data window (default: 100%).
· Or, click on the icon depicting a sub-menu and select from the choices provided.
· Or click on the “Set it” button, then select two existing points with the Bullseye cursor. The distance between the two points becomes “1 unit” of the current unit.
· Also, you may define the graduation step (stepsize) of the axis:
· Check the “Fixed graduations” check box.
· Click on the step data window and enter the value which will become the graduation step value.
If you decide to magnetize the cursor, it will be snapped to the gridpoints of a virtual grid which is defined by the axis graduations.
