In addition, 2D sketches -including the ones used to create extrusions and solid bodies- can also be constrained. There are several constraints that may be applied between the entities or bodies depending much on their actual natural geometry; sometimes these are also referred to as ’’mates’’ and include: collinearity, perpendicularity, tangency, symmetry, coincidency and parallelity among other ways of establishing the orientation of the entity. Also, a constraint on two (or more) lines may be added so these are equal in length; in the same manner, the diameter of circles can be set to have the same dimension. Moreover, a solid model can also be set to be locked or fixed in space. Depending on the program, the terminology used in the application may differ. The purpose of constraints in a design is to control and limit the behavior of the entities and bodies in relation to another entity, plane or body. Effective constraints or mates between two or more bodies may exist at the assembly level of these or between two or more entities in defining a sketch, but adding conflicting, unnecessary or redundant constraints may result in an overdefined sketch and an error message. ==Example== Ideally, a rod will need to be ''concentric'' to a hole drilled through the plate where it will be inserted, so the constraint "concentric" guarantees that the diameter of the rod and the diameter of the hole maintain a common centerline, thus "locking" the manner the rod relates to the hole in the plate, this means that the rod could still slide on either direction since the position of its ends has not been limited. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Constraint (computer-aided design)」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
