Problems solved by technology

Since the information annotation is not a whole, it is difficult to precisely control the position of the information annotation
This makes information labeling a relatively cumbersome task
Due to the low efficiency of existing information labeling methods, the CAD drawing speed is reduced

Embodiment Construction

[0068] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

[0069] An adsorption-type intelligent information labeling method for CAD systems, such as figure 1 and figure 2 As mentioned, it includes the following steps:

[0070] Step 1: increase the physical object attribute information 3 (such as the number, diameter of the steel bar, the type and height of the bridge pier, etc.) in the basic shape primitive of the CAD system to form the physical primitive, and construct the physical object attribute information access interface of the physical primitive;

[0071] Step 2: The CAD system accepts the user's selection of the physical primitive when drawing;

[0072] Step 3.1: The user extracts the physical object attribute information 3 contained in the selected physical primitive by accessing the physical object attribute information access interface of the selected physical primitive;

[0073] Step 3.2: The u...

Abstract

The invention discloses an adsorption intelligent information labeling method and device for a CAD system. The method includes the following steps that object information is added to user-defined primitives; selection of the primitives in a CAD plot by a user is received; the accessory object information of the primitives is identified; an information label is automatically generated at a designated position of the user; the adsorption function is achieved through constraint when the user drags the information label, and therefore the information label will not break away from or exceed the range of a labeled object. The device is composed of an entity primitive generation module, an entity primitive selection module, an information label generation module, an information label selection module, an information label adsorption module and a label information correction module. The adsorption intelligent information labeling method and device can improve the information labeling efficiency of drawing with the CAD software.

Description

technical field [0001] The invention relates to the technical field of CAD (Computer Aided Design, computer-aided design), in particular to an adsorption-type intelligent information labeling method and device for a CAD system. technical background [0002] In the process of using CAD technology to draw, it is necessary to mark the information of each graphic element representing the physical object. In the existing CAD technology, it is necessary to manually mark the primitives, that is, manually draw the basic primitives that make up the annotations in the CAD system in sequence. When the above-mentioned annotations interfere with other primitives, manual marking is also required. The way to move the annotation in the CAD system to remove the interference. [0003] Due to the inability to establish an overall information label, the existing CAD technology cannot draw and manage the information label as a whole graphic element object, nor can it further establish the conne...
