You can specify document-level drafting settings for all dimensions.
Dimensions that are inserted using Insert Model Items, DimXpert, and other automated methods are placed on predefined locations that radiate out from the drawing view. You set the predefined locations in this dialog box.
To display this dialog box, in a drawing, click

Stacked Fractional Dimension Size by Percentage
Bent leaders
| Leader length |
Enter the length of the unbent portion of the leader. |
Arrows
| Size

|
Offset distances
| Offset distances |
Sets the dimension distances from the model and from each successive location (as indicated by the red dotted lines in the image below).
|
| Gaps |
For baseline dimensions, specify the offset distances: - Between the model and the first dimension
extension line
- Between dimension extension lines
These values also control the spacing between dimensions that are offset from one another and from the model edge when using rapid dimensioning. |
| Annotation view layout
|
Select to use offset distances specifications from an annotation view. Clear to enter the gaps.
|
Break dimension extension/leader lines
| Gap
|
Specify the gap in broken extension and leader lines.
|
 |
| Break only around dimension arrows |
Select to display breaks only when the lines and arrows intersect.
|
To break the dimension lines, select the dimension and click Break Lines in the PropertyManager. When you break dimension lines, they break around nearby lines. If you move a dimension significantly, it might not break around nearby lines. To update the display, clear Break Lines for the selected dimension and click Break Lines again.
Extension lines
| Gap
|
Specify the distance between the model and the dimension
extension lines. This value also controls the gap between extension lines and
center marks.
|
 |
| Beyond dimension line |
Specify the length that the extension line extends beyond the
dimension line.
