Abstract

The invention relates to a method for converting two-dimensional drawings of circuit boards to three-dimensional drawings. The method comprises the following steps of: importing a two-dimensional circuit board design file; reading and analyzing data information in the two-dimensional circuit board design file; and creating a circuit board 3D model according to obtained design data information. Compared with the prior art, the method is convenient for the design of subsequent three-dimensional electrical assembly processes through converting two-dimensional drawings to three-dimensional drawings.

Description

technical field [0001] The invention belongs to the field of computer-aided design, in particular to a method for three-dimensional conversion of two-dimensional drawings of circuit boards. Background technique [0002] Existing circuit diagram design drawings present the circuit board design structure through simple plane geometry, without a three-dimensional display process, which is inconvenient for technicians to view the specific design of the circuit board from multiple angles. The traditional circuit diagram design is a two-dimensional design. At present, two-dimensional drawings are the final design results delivered by my country's electronic design industry, which is the current industry practice. Therefore, the organization and management of the production process is carried out around the production of two-dimensional drawings. Now the production of two-dimensional drawings uses a CAD platform to replace manual drawing. Two-dimensional design has low hardware ...
