Description

technical field [0001] The invention relates to a method for generating a solid model, in particular to a method for generating a three-dimensional solid model of an electric power tower. Background technique [0002] Power towers are usually used as the main type of towers in overhead transmission line projects, especially high-voltage lines. The solid model of the tower includes a refined model of each tower component such as angle steel, gusset plate, and bolts. If the fineness of the solid model is high, it can be directly used for power tower processing and optimized blanking. [0003] At this stage, due to the difficulty in constructing the solid model of the iron tower and the lack of tools, this part of the work is mainly completed by the iron tower processing manufacturer. The structural designers of iron tower manufacturers mainly analyze the force of the tower and optimize the members, and obtain the command drawing of the general structure of the tower. Such dra...

Problems solved by technology

The structural designers of iron tower manufacturers mainly analyze the force of the tower and optimize the members, and obtain the command drawing of the general structure of the tower. Such drawings cannot consider problems such as space collision of iron tower components, and due to the lack of automatic generation of three-dimensional solid models method, leading to a great reduction in the practical application value of 3D design

At present, the physical model of the transmission line tower can only be constructed by manual modeling methods. Professional 3D drafters need to draw the model manually according to the design drawings of the tower and use 3D modeling software such as 3DMax, which is not only time-consuming and costly. In the line engineering, the iron towers of the same type need to be adjusted at different positions of the towers, which leads to the inability to realize multiple reuse of the same type of iron towers. Therefore, artificial modeling is used to realize the 3D solid modeling of the entire line iron tower waste is not realistic
