SolidWork 2013 - Modifying Tools - How To Trim And Extend

Trimming Sketched Entities

CommandManager: Sketch > Trim Entities
SolidWorks menus: Tools > Sketch Tools > Trim
Toolbar: Sketch > Trim Entities

The Trim Entities tool is used to trim the unwanted entities in a sketch. You can use this tool to trim a line, arc, ellipse, parabola, circle, spline, or centerline intersecting another line, arc, ellipse, parabola, circle, spline, or centerline. You can also extend the sketched entities using the Trim Entities tool.

To trim an entity, choose the Trim Entities button from the Sketch CommandManager; the Trim PropertyManager will be displayed.
The options in this PropertyManager to trim the sketched entities are discussed below.


Message Rollout
The Message rollout in this PropertyManager informs you about the procedure of trimming and extending the sketched elements, depending upon the option selected in the Options rollout of the Trim PropertyManager.

Options Rollout
The Options rollout displays all options that are used to trim the sketched entities. These options are discussed next.

Power trim
When the Power trim button is chosen in the Options rollout, the Message rollout in this PropertyManager will inform you about the procedure of trimming and extending the sketched elements using this option.

To trim the unwanted portion of a sketch using this option, press and hold the left mouse button and drag the cursor. You will notice that a gray-colored drag trace line is displayed along the path of the cursor. When you drag the cursor across the unwanted sketched entity, it will be trimmed and a small red-colored box will be displayed in its place. You can continue trimming the entities by dragging
the cursor across them. After trimming all unwanted entities, release the left mouse button.

To extend or shorten an entity dynamically using this tool, click once on the entity and then move the cursor; the entity will extend or shorten dynamically depending upon the direction of movement. Move the cursor up to a level to which the entity has to be extended or shortened. Press the left mouse button to complete the operation.

To extend a line or a curve such that it intersects with other entity, select the first entity and then select the second entity; the first entity will extend and intersect the second entity. While extending, if the first entity cannot intersect the second entity, then the first entity will extend up to the apparent intersection point.

Corner
The Corner button in the Options rollout is used to trim or extend the sketched entities in such a way that the resulting entities form a corner.

To trim the unwanted elements using this option, choose the Corner button from the Options rollout; you will be prompted to select an entity. Select the entity from the geometry area; you will be prompted to select another entity. When you move the cursor over the second entity, the preview of the resulting entity will be displayed in a different color. In the second entity, select the portion to be retained. The selected portions of the entities will be retained and the resulting entities will form a corner.

Trim away inside
The Trim away inside button in the Options rollout is used to trim the portion of a selected entity that lies inside two bounding entities.

To trim the sketched entities using this tool, invoke the Trim PropertyManager and choose the Trim away inside button from the Options rollout; the Message rollout will be displayed informing you to select the two bounding entities, and then to select the entities to be trimmed. Select the bounding entities from the drawing area. Now, select the entities to be trimmed from the drawing area. As you select an entity to be trimmed, the portion of the entity inside the bounding entities will be removed and the portion outside the bounding entities will be retained.

Trim away outside
The Trim away outside button in the Options rollout is used to trim the portion of an entity outside the bounding entities.

 To trim the entities using this tool, invoke the Trim PropertyManager and choose the Trim away outside button from the Options rollout; the Message rollout will inform you to select the two bounding entities, and then to select the entities to be trimmed. Select the bounding entities from the drawing area. Now, select the entities to be trimmed from the drawing area. As soon as you select an entity to be trimmed, the portion of the entity outside the bounding entities will be removed and the portion inside will be retained.

Trim to closest
The Trim to closest button is used to trim the selected entity to its closest intersection.

To trim the entities using this tool, invoke the Trim PropertyManager and then choose the Trim to closest button from the Options rollout; the cursor will be replaced by the trim cursor. Move the trim cursor near the portion of the sketched entity to be removed. The entity or the portion of the entity to be removed will be highlighted in orange. Press the left mouse button to remove the highlighted entity.

You can also use this option to extend the sketched entities. To do so, move the trim cursor to the entity to be extended. When the sketched entity turns orange, press the left mouse button and drag the cursor to the entity up to which it has to be extended. You will notice the preview of the extended entity. Release the left mouse button when the preview of the extended entity appears; the entity will be extended.

You can toggle between the Trim Entities and Extend Entities tools using the shortcut menu that will be displayed on right-clicking when any one of these tools is active.


Extending Sketched Entities

CommandManager: Sketch > Trim Entities flyout > Extend Entities
SolidWorks menus: Tools > Sketch Tools > Extend
Toolbar: Sketch > Trim Entities flyout > Extend Entities

The Extend Entities tool is used to extend the sketched entity to intersect the next available entity. The tool is used to extend a line, arc, ellipse, parabola, circle, spline, or centerline to intersect another line, arc, ellipse, parabola, circle, spline, or centerline. The sketched entity is extended up to its intersection with another sketched entity or a model edge.

To do so, choose the Extend Entities button from the Trim Entities flyout in the Sketch CommandManager and move the extend

cursor close to the portion of the sketched entity that is to be extended. The entity to be extended will be highlighted and the preview of the extended entity will also be displayed. Press the left mouse button to complete the extend operation.
