Primitive selection method and device and electronic equipment

Abstract

The invention relates to the technical field of data processing, in particular to a primitive selection method and device and electronic equipment, and the method comprises the steps: obtaining the display priority of each layer in a target model; responding to a primitive selection behavior of the target model, wherein the primitive selection behavior comprises click selection or box selection; determining a target layer based on the primitive selection behavior and the display priority; adding the primitives in the target layer into a selection set and adding the primitives in other layers into an alternative set; responding to a primitive operation behavior of the target model; and determining a target primitive in the selection set and the alternative set according to the primitive operation behavior. Because the selection set and the alternative set are determined by using the display priority and the primitive selection behavior of each layer, the target primitive is determined from the selection set and the alternative set; the selection set and the alternative set comprise the corresponding primitives of all the layers, so that the cross-layer primitive operation behavior can be realized, the primitive selection efficiency is improved, the batch processing of the primitives can be realized, and the subsequent modeling efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a graphic element selection method, device and electronic equipment. Background technique [0002] In the process of a building from project approval to completion, Building Information Modeling (Building Information Modeling, referred to as BIM) software plays an indispensable role in this process, which can be used for design, budget, and measurement. [0003] Among them, a complete architectural model usually needs to be modeled using multiple layers in BIM software, and multiple graphic elements are designed in each layer. The model can be constructed through the combination of primitives in multiple layers. [0004] Existing product functions, when the user wants to modify the engineering layout modeling structure and various operations (such as copying, deleting, etc.), he can only switch to each component, select the graphic element to be operated and perform a se...
