A method and apparatus for in-situ modification of component position in modeling software

Abstract

The invention belongs to the field of building information processing and particularly relates to a method and an apparatus for in-place modification of a member position in modeling software. The method comprises: according to the properties of a member and the position of an object around the member, generating a dynamic size when activating the member; and according to the generated dynamic size, performing in-place modification on the member position. The apparatus comprises a dynamic size generation module used for generating the dynamic size when activating the member according to the properties of the member and the position of the object around the member, and a member position in-place modification module used for performing in-place modification on the member position according to the generated dynamic size. According to the method and the apparatus, dynamic sizes of the member and the reference object around the member are automatically generated by activating the member to support in-place modification of the member position, so that the convenience for designers in model modification is improved and the efficiency and flexibility of design are improved.

Description

technical field [0001] The invention belongs to the field of building information processing, and in particular relates to a method and a device for modifying component positions in-situ in modeling software. Background technique [0002] With the rapid development of urban construction, the requirements for construction output are getting higher and higher, and the structure of building products is becoming more and more complex. Therefore, architectural design is required to complete architectural products with high quality and low cost in a relatively short period of time. In order to improve design efficiency and product quality, a large number of modeling design software has been introduced into the construction industry. [0003] The architectural model is a model with complex structure and fine components. The architectural model not only includes basic elements such as walls, doors and windows, but also includes stairs, furniture equipment, surrounding environment,...

Problems solved by technology

The existing technology uses the geometric information of the component’s sub-graphics to calculate its positional relationship with the reference object. This positional relationship can also represent the relationship between the component and the reference. The generation of traditional dimensions depends on the sub-graphics of the component (such as when establishing When dimensioning the positional relationship between a cuboid component and a cylindrical component, you first need to select the sub-graphics of the cuboid and cylindrical component: surface, line, point, and calculate the dimension value representing the positional relationship according to the position of the sub-graphics), between sub-graphics The dimensional relationship represents the dimensional relationship of the component. Traditional dimensional tools are not automatically generated, but need to be manually added by the designer, which will greatly increase the modeling workload of the designer and increase the cumbersomeness of on-site modification.

Moreover, this size tool has some requirements for the 3D model that have nothing to do with the design itself, such as using a certain sub-element of the component, such as the point, surface, line, etc. It is required to comply with the full constraint rules), which will also increase the unnecessary workload of the designer, and increase the learning time of the software, especially in the process of large-scale model design.

In order to prevent designers from getting lost in the heavy work of drawing dimensions and resulting in low design efficiency, architectural design software needs to provide a simpler, more intuitive, and more flexible way to modify the position of components in situ
