Trims objects to meet the edges of other objects.
Summary
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.
List of Prompts
The following prompts are displayed.
Select cutting edges
Specifies one or more objects to be used as a boundary for the trim. TRIM projects the cutting edges and the objects to be trimmed onto the XY plane of the current user coordinate system (UCS).
Note To select cutting edges that include blocks, you can use only the single selection, Crossing, Fence, and Select All options.
-
Select objects
-
Specifies objects individually.
-
Select all
-
Specifies that all objects in the drawing can be used as a trim boundary.
Object to Trim
Specifies the object to trim. If more than one trim result is possible, the location of the first selection point determines the result.
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.
Crossing
Selects objects within and crossing a rectangular area defined by two points.
Note Some 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.
-
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.
-
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.
Note When 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.
Undo
Reverses the most recent change made by TRIM.
