About Inserting Breakline Data Into a Drawing

Insert breaklines into a drawing as polylines.

Note: You cannot insert into the drawing breaklines that you have imported from an .flt file (ASCII file format), unless you used the Break Link To File option. For information, see To Import Breaklines from a File.

You may need to insert breaklines into the drawing if you deleted the original element and did not update the surface. In this case, you can import the breakline from the breakline collection.

If any of the selected breaklines exist in the drawing, a message box is displayed stating that no breaklines are inserted into the drawing. Polyline objects are created on the current layer.

In some situations, the surface keeps breakline or contour data (a list of their point coordinates), but does not associate them with an object. This may happen, for example, when you deleted an entity that the surface depends on, but the Copy Deleted Dependent Objects option on the Definition Tab of the Surface Properties dialog box is set to Yes. In this case, the surface simply converts its reference from a drawing element to a list of points defining the object’s geometry.

To restore the reference to the object element, you can insert the data associated with the deleted breakline.
