SolidWorks用Python3二次开发入门

主要参考Solidworks Macros via Python

Solidworks 2016 API

绿色版的SolidWorks 2016: 三维机械制图 SolidWorks Premium 2016 完整绿色版

试用了一下，该绿色版有两点毛病：

第一点，直接运行win32com.client.Dispatch("SldWorks.Application")会提示“无效的类字符串”错误，补全如下注册表内容可解决（自己修改程序路径）：

Windows Registry Editor Version 5.00

第二点毛病就是，无法录制和编辑宏，会导致程序奔溃（不影响python3的API调用），暂未解决！

先开启SolidWorks，在运行下面的测试代码：

import win32com.client
import pythoncom
swYearLastDigit = 6
sw = win32com.client.Dispatch("SldWorks.Application.%d" % (20+(swYearLastDigit-2)))  # e.g. 20 is SW2012,  24 is SW2016

model = sw.ActiveDoc
modelExt = model.Extension
selMgr = model.SelectionManager
featureMgr = model.FeatureManager
sketchMgr = model.SketchManager
eqMgr = model.GetEquationMgr

print("Equation 1 is: " + eqMgr.Equation(1))
eqMgr.Equation(1, "\"myVar\" = 42")
print("Equation 1 is now: " + eqMgr.Equation(1))

END!
