Example

The Trim/Extend One Entity function is used to trim or extend a wireframeentity to the intersection of another wireframe entity.The term intersection here refers to eitherthe actual intersection of the entities or the theoretical intersectionof the entities.An example of each is shown.When using the function,the first selection is the trim/extendentity and the second selection is the trim/extendto entity.You can trim arcs, lines, or splines, and you can extendlines or arcs, but not splines, using other wireframe geometry, includingpoints, as the trim/extend to entity.The following example explains thesteps to use the function.

In the Trim Extend groupof the Utilities ribbon, click Trim One Entity.

The Trim One Entity parameters display inthe Data Entry Manager.

The first step is to select the entity thatyou want to trim.What is important here is that you select the side ofthe entity that you want to keep.Selecting the portion of the entityto keep only applies when the trimentity intersects at least one other entity.The following image showsthe entities used for this example.
In the graphics area, point to the entity that you want to trimso that it changes to the Highlight color.While the entity is displayedin the Highlight color, click to select it.Be sure to select thepart of the entity that you want to keep.

After you click the entity to trim, the entityis added to the First Entity list, and is displayed in the Selection color.

The Second Entity list is automatically given focus.
The next step is to select the trimto entity or the intersecting entity to which the trim entityis trimmed.

In the graphics area, click the entity touse as the trim to location/intersection.

When you click the trimto entity, the trim entity is trimmed to the intersection.

When using Trim Extend One Entity, you canalso extend an entity using the same steps.
Select the entity that you want toextend.
Point to the extendto (trim to) entity to define the intersection to which theentity is extended.
Notice that when you point to the trimto entity, the CAD preview is displayed.

When you click the trimto entity, the trim (extend) entity is extended to the theoreticalintersection of the two entities.

You can repeat this process for as many entitiesas needed to trim or extend them.
