METHOD AND DEVICE FOR SELECTING ENTITY IN DRAWING

摘要

The present invention discloses a method and a device for selecting an entity in a drawing, wherein the method includes that a hooked preview program corresponding to a functional instruction is invoked after the functional instruction is inputted into a Computer Aided Design (CAD) system; a pickup point in a drawing is selected; an entity in a predetermined range is filtered around the pickup point to obtain a preselected entity; the preselected entity is processed via the hooked preview program so as to pre-display a result of processing the preselected entity by the inputted instruction. An effect of a selected entity processed by a control instruction can be previewed according to the present invention, thus avoiding repeated selections of a graphic entity by a user to further improve working efficiency.
