To Trim Draft Geometry
You can trim the length of draft entities to better meet a desired drawing display.
 
* Trimming or extended a draft entity so that they extend to another entity should not completely remove any parametric associativity to a model edge. Only the length  associativity between the draft entity and the model geometry is removed. Any subsequent update of the length of the model geometry edge does not update the draft entity length.
1. On the Sketch tab, click on one of the following icons to trim or extend the draft entity:
◦ (Bound)—Trim to a specified entity or point. You first select the boundary, then the items that trim to it.
◦ (Divide at Intersection)—Create two entities from one by dividing at an intersection.
Splitting two draft entities at their intersection does not remove any parametric associativity to a model edge. Each segment is parametrically associated to the underlying edge.
◦ (Corner)—Trim two entities to their intersection. Some draft entities may be shortened while others may be extended.
2. On the Sketch tab, click the arrow next to Trim group and then click on one of the following icons to trim or extend the draft entity:
◦ (Divide by Equal Segments)—Divide a selected line into a number of equal sections. You are prompted for the number of segments. If you select multiple entities, the system divides them all the same way into equal segments. After the entity divides, the break points are highlighted.
Splitting a draft entity in multiple segments of equal length does not remove any parametric associativity with a model edge. Each segment is parametrically associated to the underlying edge. For example, if a draft line was split into N segments, and the underlying model edge is modified and increased by X, each draft segment is increased in the drawing by (X/N).
◦ (Length)—Trim to a specified length. You enter a length, then select items to trim or expand to that length.
 
* The draft entity remains collinear with the model geometry it references.
◦ (Increment)—Trim or extend by a specified increment.
 
* Type a negative value to trim the draft entity and a positive value to extend the draft entity.
3. Define how you want to trim the draft entity:
4. Select the draft entity to trim, or extend. The drawing display is updated with the draft entity modifications. Model edges are erased if an overlapping draft entity is trimmed.
 
* You can re-display erased model edges by clicking Info > Show Modified Edges. Any erased model edges are highlighted . Click View > Drawing Display > Edge Display to re-display the desired edges.
