这是solidworks二次开发中给出的例子。我修改后为什么总是红色部分出错。怎么也找不到问题。希望高手给看看。绿色的部分应该是对的吧 vb???? solidworks
[解决办法]
那就是你红色语句之前的那一句：
Set matefeature = swAssy.AddMate3(swMateCOINCIDENT, ............)
未能成功执行，返回值为 Nothing 呀。
[解决办法]
Set matefeature = swAssy.AddMate3
添加没有成功，返回的应该是Nothing
Set matefeature = swAssy.AddMate3
if not matefeature is nothing then'一般需要加人判断
'do something
end if
