Creating Datum Dimensions
To create a datum dimension:
1. Press DIMENSION 1
2. Pick a datum dimension command (DATUM LONG, DATUM SHRT or COORDINATE).
3. Select MANUAL or AUTO placement.
4. Pick an orientation option, the default is Parallel.
5. Complete the selection sequence required by the option. All options allow you apply dimensioning to a single drawing element or to a group of elements.
6. If you selected MANUAL placement, move the dimension trace around your drawing until the dimension text is in the desired location. If multiple drawing elements are selected, the trace shows all proposed dimensions at the same time. Pick the desired text location and Creo Elements/Direct Drafting draws the dimension(s).
If you selected AUTO, all the dimensions are positioned automatically and the trace is not used. AUTO placement only applies when you have selected multiple elements for dimensioning.
7. To continue datum dimensioning, identify the next dimension point.
8. Press END to end this command.
The orientation options are:
Parallel
Parallel to a line drawn between two dimension points.
Horizontal
In a horizontal plane.
Vertical
In a vertical plane.
Perpend to
Perpendicular to a reference line on your drawing.
Parall to
Parallel to a reference line on your drawing.
