# OVERKILL Command Line [GstarCAD 2027](Help%20System/GSTARCAD/2027/Index.md) → [Commands](Help%20System/GSTARCAD/2027/Commands/(Commands).md) → [O](Help%20System/GSTARCAD/2027/Commands/O/(O).md) ## Function Description: This command is used to remove duplicate or overlapping lines, arcs and polylines, as well combine partially overlapping or contiguous objects. ## Command Prompts: ``` Select object: Current settings: Tolerance=0.000001, Ignore=None, Optimize polylines=YES, Combine partial overlap=YES, Combine end-to-end=YES Enter an option to change [Done(D)/Ignore(I)/tOlerance(O)/optimize Plines(P)/combine parTial overlap(T)/combine Endtoend(E)]: ``` ## Select object Specifies the object to modify. ## Done Overkills the specified objects according to the current settings. ## Ignore Ignores one or more of the following properties during object comparison. ``` Ignore [None(N)/All(A)/Color(C)/LAyer(LA)/Ltype(L)/LWeight(LW)/plotSTyle(ST)]: ``` ## tOlerance Specifies the numerical precision of object comparison. OVERKILL compares according to this value to determine the object duplication. The smaller the tolerance value, the smaller the error. ``` Specify tolerance for object comparison precision <0.000001>: ``` ## optimize Plines ``` Optimize segments within plines [YES(Y)/NO(N)]: ``` - YES: Enabled by default. When selected, individual line and arc segments within selected polylines are examined. Duplicate vertices and segments are removed. - NO: Forces OVERKILL to examine polyline segments individually. Polyline segments may be deleted as duplicates of non-polyline objects. ## combine parTial overlap ``` Combine co-linear objects that partially overlap [YES(Y)/NO(N)] : ``` - YES: Overlapping objects area combined into single objects. - NO: Overlapping objects are not combined. ## combine Endtoend ``` Combine co-linear objects when aligned end to end [YES(Y)/NO(N)]: ``` - YES: Objects that have common endpoints are combined into single objects. - NO: Co-linear objects when aligned end to end are not combined. --- [Original help](https://www.gstarcad.net/help/GstarCAD_2027_en-US/detail/commandReferences/OVERKILL_CLI.html) · © Gstarsoft Co., Ltd.
