How can I modify the grid annotations on my drawings?
Select the grid in the drawing model and use the edit handles to make modifications.
Independent grid annotation allows you to manipulate individual grid lines and grid line extensions in the 2D drawing view. Simply select the grid line and there will be handles which allow you to move the ends of the grid line, create, modify and delete a gap in the grid line, create, modify and delete doglegs, and move and hide the grid labels.
Independent elevation annotation allows you to manipulate elevation annotation in 2D section and elevation drawings. Labels can be enabled and disabled, leaders can be modified and offset, and gaps created in the floor lines.
