Work with broken sketch entities

The nailboard broken sketch entity is similar to the standard Autodesk Inventor broken view. It represents a length of wire, cable wire, or segment you specify for removal. Removing the specified length, shortens the harness object in the nailboard drawing. You can use the broken sketch entity anywhere along the length of a segment or unrouted wire or cable wire that does not contain a splice. You cannot break a routed wire, spliced wire, cable conductor, ribbon cable or any break symbol.

Sketches are often broken when the sketch exceeds the length of the drawing and scaling the sketch to fit the drawing makes the sketch too small. Sketches are also broken when the sketch contains large areas of nondescript geometry, such as the center portion of a cable wire that is free of features.

How does dimensioning a segment and a broken segment differ?

When a segment is broken, you can only place dimensions between the two endpoints of the segment and not to segment midpoints. Segments that are not broken can be dimensioned to both endpoints and midpoints. In both cases, the dimension value represents the length without the break.

How is the broken sketch changed?

With the nailboard broken sketch entity, you can:

How do harness assembly updates affect broken sketches?

If an update to the harness assembly causes a wire or segment length to change and that wire or segment has a break in it, the original value of the break is maintained. The break is removed if the updated segment or wire length is less than the break length plus 1 inch.
