Example

The Trim Extend Strings function is used to trim or extend entitiesso that they form a continuous string or chain of entities.This is donein a continuous order along open or closed chains.You can apply the processshown in the following example to use the function.

  1. In the Trim Extend groupof the Utilities ribbon, click Trim Strings.

    The Trim Strings parameters display in the Data Entry Manager.

  2. In the graphics area, point to the first entity that you want totrim so that it is displayed in the Highlight color.



  3. While the entity is displayed in the Highlight color, click toselect it.

    After you select the entity, it is added to the First Entity list, and is displayedin the Selection color.



    The next step is to select the trimto entity.This may result in entities being trimmed or extended,based on the selections.In this example, we extend the arc and the lineto meet.

  4. In the graphics area, select the nextentity to trim or extend.



    When you select the second entity, the entitiesare trimmed or extended until they connect, and the last selected entity is placed in the First Entity list.



    Notice that the second entity is now displayedin the Selection color.This is now the current trim entity.

  5. In the graphics area, select the nextentity to trim or extend.



    The entities are trimmed or extended untilthey are connected.

  6. Select the next entity.



  7. Continue selecting the entities totrim or extend.





  8. To end the function, click Cancel.

Note: The final geometry is now a closed chain.All of the entities createdusing Trim Extend Strings are single entities.What this means is thatwhen an entity is extended, the software does not add a new entity, itreplaces the previous entity with one new entity.Note that when usingsplines, as in the last entity of this example, you can only trim to them,you can't extend a spline to another entity.

This concludes the example.
