一、连接SolidWorks 二次开发
二、另存文件函数：SaveAs

1.SaveAs函数定义
2.SaveAs函数的使用

二、另存文件函数：SaveAs

使用SaveAs函数进行文件的另存

1.SaveAs函数定义

   ByVal Options As System.Integer, _
   ByVal ExportData As System.Object, _
   ByRef Errors As System.Integer, _
   ByRef Warnings As System.Integer _
) As System.Boolean

参数说明：

swFileSaveAsNotSupported	4096 or 0x1000 = Save As operation:is not supported was executed is such a way that the resulting file might not be complete, possibly because SOLIDWORKS is hidden; if the error persists after setting SOLIDWORKS to visible and re-attempting the Save As operation, contact SOLIDWORKS API support.
swFileSaveFormatNotAvailable	32 or 0x20 = Save As file type is not valid
swFileSaveRequiresSavingReferences	8192 or 0x2000 = Saving an assembly with renamed components requires saving the references

swGenericSaveError	1 or 0x1
swReadOnlySaveError	2 or 0x2

返回值，返回布尔类型，保存成功放回true，失败返回falese

2.SaveAs函数的使用

2.1除PDF文件外，其他文件另存为新文件只需修改以下代码中的STEP为对应格式后缀名即可，以下代码示例将文件另存为STEP格式

另存为其他文件时需要修改STEP为对应文件格式后缀名

filename=filename[:-6]+‘STEP’

完整代码如下

import win32com.client
import pythoncom

def saveasfile():
    # SolidWorks年份版本
    sldver=2018
    # 建立com连接,如只有一个版本,可以只写"SldWorks.Application"
    swApp=win32com.client.Dispatch(f'SldWorks.Application.{sldver-1992}')
    # 提升API交互效率
    swApp.CommandInProgress =True
    # 显示SolidWorks界面
    swApp.Visible =True
    # 获取当前激活文档对象
    swModel = swApp.ActiveDoc
    # 获取当前激活文件路径
    filename=swModel.GetPathName
    #将当前文件另存为step格式文件,路径为当前文件路径
    filename=filename[:-6]+'STEP'
    # SaveAs在此对象下调用
    swModel=swModel.Extension
    #错误和警告
    Errors=win32com.client.VARIANT(pythoncom.VT_BYREF | pythoncom.VT_I4, -1)
    Warnings=win32com.client.VARIANT(pythoncom.VT_BYREF | pythoncom.VT_I4, -1)
    # 除PDF文件外,其余格式SaveAs第四个参数均使用Nothing
    Nothing = win32com.client.VARIANT(pythoncom.VT_DISPATCH, None)
    boolstatus = swModel.SaveAs(filename,0,0,Nothing, Errors, Warnings)
    if boolstatus:
        print('文件另存成功')
    else:
        print(f'文件另存失败,出现如下错误：{Errors}')
        print(f'文件另存失败,出现如下警告：{Warnings}')

if __name__ == '__main__':
    saveasfile()

2.2PDF文件另存时，需对ExportData进行定义，将后缀名修改为PDF，以下代码示例将文件另存为3D PDF文件格式

相比2.1代码增加的代码如下

# 指定文件类型的数据接口 swExportPDFData = swApp.GetExportFileData(1) # 将文件另存为3D PDF 格式 swExportPDFData.ExportAs3D = True

完整代码如下

import win32com.client
import pythoncom

def saveasfile():
    # SolidWorks年份版本
    sldver=2018
    # 建立com连接,如只有一个版本,可以只写"SldWorks.Application"
    swApp=win32com.client.Dispatch(f'SldWorks.Application.{sldver-1992}')
    # 提升API交互效率
    swApp.CommandInProgress =True
    # 显示SolidWorks界面
    swApp.Visible =True
    # 获取当前激活文档对象
    swModel = swApp.ActiveDoc
    # 获取当前激活文件路径
    filename=swModel.GetPathName
    #将当前文件另存为step格式文件,路径为当前文件路径
    filename=filename[:-6]+'PDF'
    # SaveAs在此对象下调用
    swModel=swModel.Extension
    #错误和警告
    Errors=win32com.client.VARIANT(pythoncom.VT_BYREF | pythoncom.VT_I4, -1)
    Warnings=win32com.client.VARIANT(pythoncom.VT_BYREF | pythoncom.VT_I4, -1)
    # 指定文件类型的数据接口
    swExportPDFData = swApp.GetExportFileData(1)
    # 将文件另存为3D PDF 格式
    swExportPDFData.ExportAs3D = True
    boolstatus = swModel.SaveAs(filename,0,0,swExportPDFData, Errors, Warnings)
    if boolstatus:
        print('文件另存成功')
    else:
        print(f'文件另存失败,出现如下错误：{Errors}')
        print(f'文件另存失败,出现如下警告：{Warnings}')

if __name__ == '__main__':
    saveasfile()
