What command is used to trim an object in AutoCAD?

The command used to trim an object in AutoCAD is TRIM. This command allows users to remove portions of objects that extend beyond an intersecting edge or boundary, effectively "trimming" the object to fit within specific limits or to the desired shape.

When using the TRIM command, you first select the cutting edges, which establishes the boundaries for the trim operation. Then, you choose the objects you want to trim. This method is highly efficient, as it helps in maintaining the cleanliness and clarity of your drawings by eliminating unwanted segments, thus allowing for better organization and visual appeal in the design.

The other options do not serve the purpose of trimming objects. For instance, the CUT command may sound like it deals with cutting, but it is not a standard command in AutoCAD for trimming. SPLIT is primarily used to divide an object into separate segments without removing parts of it, and EDIT is a general reference that does not specify a particular action related to trimming objects. Therefore, TRIM is the precise command specifically designed for modifying the shape and size of objects by removing excess parts.
