Embodiment Construction

[0013] In CAD, there is an attribute definition that can contain attribute characteristics, such as tags (names that identify the attribute), hints displayed when inserting a block, information about values, text format, position in the block, etc. When a block (BLOCK) includes an attribute, the user will be prompted to input the value of the related attribute according to the definition of the attribute when the block is inserted. Through certain programming, users can read and modify these values ​​(property information), and perform corresponding operations on the tiles according to these values.

[0014] The present invention defines an elevation block including elevation symbols and related attributes, and defines a group of operation methods for extracting attribute values, modifying attribute values, and modifying elevation modules according to attribute values ​​when operating the elevation block, thereby realizing A method to automatically update the elevation value. ...

Abstract

The invention discloses an automatic elevation value updating method in computer aided design. The automatic elevation value updating method comprises the steps that a, an elevation segment is defined, the elevation segment comprises an elevation sign and a property variable related to elevation characteristics, and the elevation sign can mark the position where an elevation is located; b, graphic elements comprising the elevation segment are operated. According to the automatic elevation value updating method, after designers adopt the elevation segment to draw the elevation, when drawing modification relates to the elevation segment, an elevation value of the elevation segment in the drawing can be automatically updated through a corresponding operation method, and therefore automatic updating of the elevation value in the computer aided design is achieved.

Description

technical field [0001] This invention relates to computer aided design (CAD). In particular, it relates to a method for automatically updating elevation values ​​in computer-aided design. Background technique [0002] In the current design industry, CAD technology has been widely used. It has the advantages of fast drawing, convenient modification, and automatic update of associated annotations, so that designers can concentrate on detail design instead of checking dimensions too much. [0003] In civil engineering design, section drawings (elevation drawings) must be drawn, including a large number of elevation marks. There is no way to automatically update the elevation value in the current CAD. When drawing the elevation, the elevation symbol only marks the position of the marked elevation, and the artificially input elevation value only represents the elevation value of the elevation position. Once the design drawings involve changes in the elevation system (from rela...
