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

函数原型如下：

Function SaveAs( _
   ByVal Name As System.String, _
   ByVal Version As System.Integer, _
   ByVal Options As System.Integer, _
   ByVal ExportData As System.Object, _
   ByRef Errors As System.Integer, _
   ByRef Warnings As System.Integer _
) As System.Boolean

Name：另存文件的全路径名称，包含后缀名，包含以下选项
**Version **：另存文件时的格式，包含以下选项

Member	Description

swSaveAsOptions_OverrideSaveEmodel	32 or 0x20; Saves eDrawings-related information into a section of the file being saved; specifying this setting overrides the Tools, Options, System Options, General, Save eDrawings data in SOLIDWORKS document setting; not a valid option for IPartDoc::SaveToFile2
swSaveAsOptions_SaveEmodelData	Obsolete.
swSaveAsOptions_SaveReferenced	4 or 0x4; Supports parts, assemblies, and drawings; this setting indicates to save all components (sub-assemblies and parts) in both assemblies and drawings; if a part has an external reference, then this setting indicates to save the external reference
swSaveAsOptions_Silent	1 or 0x1
swSaveAsOptions_UpdateInactiveViews	16 or 0x10; Not a valid option for IPartDoc::SaveToFile2; this setting is only applicable for a drawing that has one or more sheets; this setting updates the views on inactive sheets

ExportData：另存文件为PDF时的选项

Errors：另存文件出现错误的定义，包含如下选项

Member	Description
swFileLockError	16 or 0x10
swFileNameContainsAtSign	8 or 0x8 = File name cannot contain the at symbol (@)
swFileNameEmpty	4 or 0x4 = File name cannot be empty
swFileSaveAsBadEDrawingsVersion	1024 or 0x400
swFileSaveAsDoNotOverwrite	128 or 0x80 = Do not overwrite an existing file

swFileSaveAsNameExceedsMaxPathLength	2048 or 0x800 = File name cannot exceed 255 characters
swFileSaveAsNoSelection	512 or 0x200 = Save the selected bodies in a part document. Valid option for IPartDoc::SaveToFile2; however, not a valid option for IModelDocExtension::SaveAs
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
swFileSaveWithRebuildError	Obsolete = See swFileSaveWarning_e
swGenericSaveError	1 or 0x1
swReadOnlySaveError	2 or 0x2

Warnings：另存文件出现警告的定义，包含如下选项

Member	Description
swFileSaveWarning_AnimatorCameraViews	128 or 0x80
swFileSaveWarning_AnimatorFeatureEdits	16 or 0x10
swFileSaveWarning_AnimatorLightEdits	64 or 0x40

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
