Use this procedure to automatically create a profile or shrinkwrap outline around any collection of contiguous linework entities, including architectural objects. The visual result of the procedure is similar to merging the entities, but in this case the outline you create is a separately selectable entity. Unlike the other AEC Linework Tools, the Shrinkwrap tool is accessed from the General tool palette. The AECLINEWORKSHRINKWRAP command the tool invokes is wrapped in a DesignCenter command to accommodate layer keying (that is, shrinkwrap polylines created using this tool are automatically placed on a particular layer as specified by the associated layer key).
All objects within the shrinkwrap remain selected. You can now select and move the shrinkwrap profile independently of the linework it encloses.
