Splitting Dimension and Extension Lines at Intersecting Entities

Use the SplitDimension command to split dimension and extension lines of Dimension entities where they intersect other entities. You can also join split dimension and extension lines.

You can either create splits in the dimension and extension line automatically at all intersections with other entities, or you can specify the split locations individually by selecting crossing entities one by one.

You can create dimension splits at Lines, Polylines, Arcs, Circles, Ellipses, Splines, Leaders, Notes, SimpleNotes, and other Dimensions. Splits are also created at entities of these types when they are part of Blocks or References. You can select the same entities when you rejoin split dimensions.

The default gap size is stored in DimensionStyles.
