Example: Witness Lines for Intersection References
Intersecting Entities and References
Intersection Witness Lines
1. First entity
2. Intersection reference
3. Second entity
Intersection witness lines are created. Both the entities are straight lines. You must extend both the lines to obtain the intersection.
1. First entity
2. Intersection reference
3. Second entity
Intersection witness lines are not created.
The intersection reference lies on the second entity.
1. First entity
2. Intersection reference
3. Second entity
Intersection witness lines are not created.
Though both entities are straight lines they intersect without being extended.
1. First entity
2. Intersection reference
3. Second entity
Intersection witness lines are not created as the second entity is a curve.
