基于VB 的solidworks二次开发的API
下面是我对solidworks中API一个过程的修改，进行向转配体中添加零件然后再装配。
但是倒数第三行总是出现对象变量或with块未设置。请问是那出错了。先谢谢各位了，小弟注册，捧个场。

End Sub
vb api solidworks
[解决办法]
Set matefeature = swAssy.AddMate3(swMateCOINCIDENT, swMateAlignALIGNED, False, 0, 0, 0, 0, 0, 0, 0, 0, False, mateError)
if not matefeature is nothing then
matefeature.Name = MateName
swModel.ViewZoomtofit2
end if
set后，可能返回Nothing，要加入判断
至于为何会返回Nothing，要查文档说明，solidwork的帮助文档有详细的说明
