TRIM
 
 
 

Trims objects to meet the edges of other objects.

Access Methods

Button

 Ribbon: Home tabModify panelTrimNot available on the ribbon in the current workspace.
 Menu: Modify  TrimNot available in menus in the current workspace
 Toolbar: Modify 
 Command entry: trim

To trim objects, select the boundaries. Then press ENTER and select the objects that you want to trim. To use all objects as boundaries, press ENTER at the first Select Objects prompt.

Current settings: Projection = current, Edge = current

Select cutting edges...

Select objects or <select all>: Select one or more objects and press ENTER, or press ENTER to select all displayed objects

Select the objects that define the cutting edges to which you want to trim an object, or press ENTER to select all displayed objects as potential cutting edges. TRIM projects the cutting edges and the objects to be trimmed onto the XY plane of the current user coordinate system (UCS).

NoteTo select cutting edges that include blocks, you can use only the single selection, Crossing, Fence, and Select All options.

Select object to trim or shift-select to extend or [ Fence/ Crossing/ Project/ Edge/ eRase/ Undo]: Select an object to trim, hold down SHIFT and select an object to extend it instead, or enter an option

Specify an object selection method to select the objects to trim. If more than one trim result is possible, the location of the first selection point determines the result.

Object to Trim

Specifies the object to trim. The prompt for selecting the object to trim repeats so you can trim multiple objects. Press ENTER to exit the command.

Shift-Select to Extend

Extends the selected objects rather than trimming them. This option provides an easy method to switch between trimming and extending.

Fence

Selects all objects that cross the selection fence. The selection fence is a series of temporary line segments that you specify with two or more fence points. The selection fence does not form a closed loop.

Specify first fence point: Specify the starting point of the selection fence

Specify next fence point or [Undo]: Specify the next point of the selection fence or enter u

Specify next fence point or [Undo]: Specify the next point of the selection fence, enter u, or press ENTER

Crossing

Selects objects within and crossing a rectangular area defined by two points.

Specify first corner: Specify a point

Specify opposite corner: Specify a point at a diagonal from the first point

NoteSome crossing selections of objects to be trimmed are ambiguous. TRIM resolves the selection by following along the rectangular crossing window in a clockwise direction from the first point to the first object encountered.

Project

Specifies the projection method used when trimming objects.

Enter a projection option [None/Ucs/View] <current>: Enter an option or press ENTER

None

Specifies no projection. The command trims only objects that intersect with the cutting edge in 3D space.

UCS

Specifies projection onto the XY plane of the current UCS. The command trims objects that do not intersect with the cutting edge in 3D space.

View

Specifies projection along the current view direction. The command trims objects that intersect the boundary in the current view.

Edge

Determines whether an object is trimmed at another object's extrapolated edge or only to an object that intersects it in 3D space.

Enter an implied edge extension mode [Extend/No extend] <current>: Enter an option or press ENTER

Extend

Extends the cutting edge along its natural path to intersect an object in 3D space.

No Extend

Specifies that the object is trimmed only at a cutting edge that intersects it in 3D space.

NoteWhen trimming hatches, do not set Edge to Extend. If you do, gaps in the trim boundaries will not be bridged when trimming hatches, even when the gap tolerance is set to a correct value.

Erase

Deletes selected objects. This option provides a convenient method to erase unneeded objects without leaving the TRIM command.

Select objects to erase or <exit>: Use an object selection method and press ENTER to return to the previous prompt

Undo

Reverses the most recent change made by TRIM.
