求助，犀牛重装后封闭曲线挤出 默认选项不是实体
每次曲线挤出都要按一次S，重装软件前都是自动默认实体

I think I found out…
Go to the Extrude Straight button
Press SHIFT + Right mouse button to open Button Editor
In Button Editor, go to Command, in your case should appear something like this:
! _ExtrudeCrv _Pause
_Solid=_No
You only have to change to
! _ExtrudeCrv _Pause
_Solid=_Yes
There you go, every time you click on that button, it will extrude capped!

Nice ! Thank you

其实没必要把NO改成YES，因为犀牛有两个挤出命令，一个是曲面下，还有一个是实体下的挤出，使用实体下的挤出每次都是默认实体，既然分出来两个命令，我想肯定是有道理的
