Insert breaklines into a drawing as AutoCAD polylines.
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 Importing Breaklines from a File.
You may need to insert breaklines into the drawing if you deleted the original entity 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 (Surface Properties Dialog Box) page of the Surface Properties dialog box is set to Yes. In this case, the surface simply converts its reference from a drawing entity to a list of points defining the object’s geometry.
To restore the reference to the object entity, you can insert the data associated with the deleted breakline.
To insert breakline data into the drawing
- Click the surface Breaklines collection in the Prospector tree.
The breaklines with their descriptions and types are displayed in the Prospector list view.
- Right-click a breakline operation in the list view and click Insert to Drawing.
- If the breakline objects in the breakline operation do not exist in the drawing, they are added to the drawing as polyline objects.
- If the breaklines exist in the drawing, a message box is displayed stating that no breaklines are inserted into the drawing.
