SolidWorks VBA 脚本：自动保存工程图、PDF、DWG 和 STEP 文件

This code is written in VB.NET and is used to automate the process of saving engineering drawings in different file formats and saving related parts in a specific folder. It uses the SolidWorks API to perform these tasks.

The code first declares a SolidWorks application object and sets it to the current SolidWorks session. It then declares a model object and sets it to the active document. It also declares a selection manager object to manage the selection of different objects in the model.

The code then gets the name of the current document and saves it as a PDF and DWG file in a specific folder. It then gets the referenced documents in the model and checks if they are of type part. If so, it opens the part and saves it as a STEP file in the same folder.

Overall, this code can be useful for automating the process of saving engineering drawings and related parts in different file formats, which can save time and increase productivity.
