Embodiment Construction

[0021] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0022] On the basis of the 3D design integration system, each solid model has its own spatial position, judge whether the target object collides with other models of the system in the 3D model space, and export the collision results, figure 1 It is a flow chart of a method for checking the collision of power plant components with a three-dimensional model, the method includes the following steps:

[0023] a. Select the target object in the three-dimensional model space of the system, and store the three-dimensional coordinate values ​​of each point of the solid model of the target object; for example: the selected target object is "J0902-LBA-main steam pipeline installation drawing";

[0024] b. In the 3D model space of the system, select the range where the solid model that needs to be checked for collision is located, and store the 3D coordinate values ​​of all poin...

Abstract

The invention discloses a method for inspecting the element collision of a power generation plant by a three-dimensional model, which is applied to the design process of large industrial and mining enterprises, such as a power plant, and the like. All elements in the design of the power plant are modeled on the basis of a three-dimensional design integrating system, and an entity model in a three-dimensional space carries out collision inspection by a computer program and guides a collision list, thereby achieving the aim of detecting whether an entity and the occupied space thereof generate collision or not. The invention solves the problem of accurate detection of the collision, can lead all professions to view a detecting result in a qualification promoting way, prevents secondary detection, greatly saves time and improves the working efficiency.

Description

technical field [0001] The invention relates to a method for three-dimensional design, in particular to a method for checking whether components may collide and interfere with each other, which is applied in the field of three-dimensional design of electric power engineering. Background technique [0002] Power systems such as power plants have a lot of equipment and pipelines. During the engineering design and construction of power systems, there is a great possibility that various equipment and pipelines will collide and interfere with each other, and the power system design process is designed by specialization. , Different types of components are designed by different professionals. If the existence of these collisions cannot be found and corrected in time during the engineering design process, it will inevitably lead to failure of construction during the construction process, which requires on-site changes in the location or direction of equipment and pipelines, or remo...
