Background
Currently, the three-dimensional design software NX under the Siemens flag is the mainstream three-dimensional design software in the fields of environmental test equipment, mold manufacturing, teaching model design, traditional machinery and the like. With the expansion of market demands, the data volume of designers using NX designs is increasing, and most designs need to make two-dimensional engineering drawings.
For the teaching industry demand model, two ways are available for making the two-dimensional engineering drawing. One is to redesign the whole according to the scaled down model size. The other is to use the existing entity size model to scale it down and then modify the confusing and wrong dimensions in the engineering drawing. Designers often scale volume commands with three-dimensional models for the purpose of quickly achieving equal scaling and minimizing modifications. Firstly, the scaling of parts is realized, then, error constraint in an assembly body and the size of confusion and errors in a two-dimensional diagram of parts are modified, and finally, the parts are manufactured. The method has larger workload and is easy to generate errors such as assembly constraint, size failure and the like.
