This is a new feature in Revit 2012. You can access it by double clicking on the text of any dimension segment. Have a look at the images below for more information:
Segment Dimension Leader Visibility drop-down box
Some possible combinations
What I really want is a global override or option to turn dimension leaders ON or OFF for all newly created dimensions…
In another post, I discussed the feedback form that allows you to make suggestions directly to Autodesk.
Yesterday, I made this suggestion: When overriding a Category in view by using: Select element Right click Override – graphics in view The resulting dialog should give focus to the relevant ‘line’. For instance, if I choose to override Railings, the dialog appears but the line for Railings is not visible – you need to scroll down to find this line in the V/G dialog. The dialog should automatically scroll and give focus to the appropriate line. Luke
And received this response:Thank you for contacting us with your feedback. When applying the override the category does get selected but the box does not scroll. It would be a nice touch if it did that action for you as well as selecting the category. I will pass this suggestion along to the development team for further consideration.If you have a valid suggestion, I recommend that you click on the feedback form below and make yourself heard:
Let’s say you have isolated a few categories, and you have included Dimensions so that they are still visible.
However, your dimensions are no longer showing the Centerline symbol text – do you know why?
It is because this item is on a different category to dimensions themselves. In my case, I had to turn on the ‘Generic Annotation’ category in order to show this text.
