Datum dimensioning allows a datum position to be set using the Set Datum command Datum Dimension button. Datum dimensions can be added to the drawing which measure from this datum point.

Once selected the Ribbon changes to show the current dimension properties and the command prompt reads:

Give Dimension Point:

Indicate the point to dimension to using any of the snaps and input options as shown below.

Give Text Point:

The dimension text and leader line move with the cursor and the dimension will flip between the TOP, RIGHT, BOTTOM & LEFT quadrants separated by the grey lines in the diagram below. Once the desired position is achieved click to accept it.

If no datum has been set, the system will take the drawing origin as the datum. If a datum point is added to the drawing or moved then the datum dimensions can be updated automatically by selecting the Refresh command.
