Resizing entities

 

You can change the size of an entity or set of entities by stretching, scaling, extending, trimming, or editing their lengths.

 

Stretching entities

 

You can change the size of entities by stretching them. When you stretch entities, you must select the entities using either a crossing window or a crossing polygon. You then specify a displacement distance or select a base point and a displacement point. Entities that cross the window or polygon boundary are stretched; those completely within the crossing window or crossing polygon are simply moved.

 

To stretch an entity

 

Do one of the following to choose Stretch:

 

  • On the ribbon, choose Home > Stretch (in Edit).
  • On the menu, choose Modify > Stretch.
  • On the Modify toolbar, click the Stretch tool.
  • Type stretch and then press Enter.

 

In the prompt box, choose Crossing Window or Crossing Polygon.

 

Select the entities, and then press Enter.

 

Specify the base point.

 

Specify the second point of displacement

 

  • On the ribbon, choose Home > Stretch (in Edit).
  • On the menu, choose Modify > Stretch.
  • On the Modify toolbar, click the Stretch tool.
  • Type stretch and then press Enter.

To stretch an entity using grips, you select it to display its grips and then select a grip to make it the active grip. This becomes the base point. Then you move the active grip to a new location. The grip you select depends on the type of entity you’re modifying. For example, to stretch one corner of a rectangle, select the corner point grip. To stretch a line, select an endpoint grip. Not all entities can be stretched using grips.

 

To stretch an entity using grips

 

Select the entity.

 

Click a grip to activate it.

 

Drag the grip.

 

Click to release.

Scaling entities

 

You can change the size of a selected entity by scaling it in relation to a base point. You can change the size of an entity by specifying a base point and a length, which is used as a scale factor based on the current drawing units, or by specifying a scale factor. You can also use a scale factor referenced to a base scale factor, for example, by specifying the current length and a new length for the entity.

 

To scale a selection set by a scale factor

 

Do one of the following to choose Scale:

 

  • On the ribbon, choose Edit > Scale (in Modify).
  • On the menu, choose Modify > Scale.
  • On the Modify toolbar, click the Scale tool.
  • Type scale and then press Enter.

 

Select the entities, and then press Enter.

 

Specify the base point.

 

Specify the scale factor.

You can also scale some entities using grips. To scale an entity, you select the entity, and then click a grip. You then change the size of the entity by moving the grip. The grip you select depends on the type of entity you’re modifying. For example, to scale a circle, select a quadrant point grip.

 

To scale an entity using grips:

 

Select the entity.

 

Click a grip to select it.

 

Drag the grip.

 

Click to release.

Extending entities

 

You can extend entities so that they end at a boundary defined by other entities. You can also extend entities to the point at which they would intersect an implied boundary edge. When extending entities, you first select the boundary edges, and then specify the entities to extend, selecting them either one at a time, using the fence selection method, or the projection selection method.

 

You can extend arcs, lines, two-dimensional polylines, and rays. Arcs, circles, ellipses, lines, splines, polylines, rays, infinite lines, and viewports on a Layout tab can act as boundary edges.

 

To extend an entity

 

Do one of the following to choose Extend:

 

  • On the ribbon, choose Edit > Extend (in Modify).
  • On the menu, choose Modify > Extend.
  • On the Modify toolbar, click the Extend tool.
  • Type extend and then press Enter.

 

Select one or more entities as boundary edges, and then press Enter.

 

Select the entity to extend.

 

Select another entity to extend, or press Enter to complete the command.

To extend an entity to an implied boundary

 

Do one of the following to choose Extend:

 

  • On the ribbon, choose Edit > Extend (in Modify).
  • On the menu, choose Modify > Extend.
  • On the Modify toolbar, click the Extend tool.
  • Type extend and then press Enter.

 

Select one or more boundary edges, and then press Enter.

 

In the prompt box, choose Edge Mode.

 

In the prompt box, choose Extend.

 

Select the entity to extend.

 

Select another entity to extend, or press Enter to complete the command.

To extend several entities using the fence selection method

 

Do one of the following to choose Extend:

 

  • On the ribbon, choose Edit > Extend (in Modify).
  • On the menu, choose Modify > Extend.
  • On the Modify toolbar, click the Extend tool.
  • Type extend and then press Enter.

 

Select one or more boundary edges, and then press Enter.

 

In the prompt box, choose Fence.

 

Specify the first point of the fence.

 

Specify the second point of the fence.

 

Specify the next fence point, or press Enter to complete the command.

When you extend a wide polyline, its centerline intersects the boundary edge. Because the end of the polyline is always cut at a 90-degree angle, part of the polyline may extend past the boundary edge. A tapered polyline continues to taper until it intersects the boundary edge. If this would result in a negative polyline width, the ending width changes to 0.

Trimming entities

 

You can clip, or trim, entities so they end at one or more implied cutting edges defined by other entities. You can also trim entities to the point at which they would intersect an implied cutting edge. When trimming entities, you first select the cutting edges and then specify the entities to trim, selecting them either one at a time or using the fence selection method.

 

You can trim arcs, circles, lines, open two-dimensional and three-dimensional polylines, and rays. Arcs, circles, lines, polylines, rays, infinite lines, and viewports on a Layout tab can act as cutting edges. An entity can be both a cutting edge and one of the entities being trimmed.

 

To trim an entity

 

Do one of the following to choose Trim:

 

  • On the ribbon, choose Edit > Trim (in Modify).
  • On the menu, choose Modify > Trim.
  • On the Modify toolbar, click the Trim tool.
  • Type trim and then press Enter.

 

Select one or more cutting edges, and then press Enter.

 

Select the entity to trim.

 

Select another entity to trim, or press Enter to complete the command.

Specify the first point of the fence.

Editing the length of entities

 

You can change the length of entities or the included angle of arcs. Use any of the following methods to change the length of an entity:

 

  • Dynamically drag the endpoint or angle.
  • Specify an incremental length or angle measured from an endpoint.
  • Specify the new length as a percentage of the total length or angle.
  • Specify a new length or included angle.

 

You can change the length of arcs, lines, and open polylines.
