Datum Step
You may find that your datum dimensions are positioned too close together. This section shows how to specify a vertical distance (or step) between each subsequent datum dimension line.
The Creo Elements/Direct Drafting default for this distance is 8 mm. The distance is active for the Datum Long and Datum Short commands.
To specify a datum step:
1. Click the Line tab in Dimension Settings.
2. Enter a new distance value into the Datum Step field.
Creo Elements/Direct Drafting sets the vertical distance to the new value.
3. Complete, or start the dimensioning command.
Creo Elements/Direct Drafting steps the dimension line for each dimension.
Following figure shows the difference between:
• Datum dimensioning without using Datum Step (datum step distance is 0). This produces a poor quality dimension where the dimension text has been overwritten by the dimension lines.
• Datum dimensioning using Datum Step (datum step distance is 10).
