What is it you really want to know about it? You should be able to orbit around and see that the edge passes through the face.

I mean have any plugins to do it?

i mean have any plugins do this?

Why you need a plugin to draw a line? Have you tried what I suggested?

you are right ,i doesn't need a plugin to draw a line.

in fact ,my problem is ,like the picture,there are many faces inside the wall ,but i do not need them.
these faces makes the wall not a solid,and i need to do union.
is there a way to make the way to be a solid?
thanks

Ok, that's a different question.
How is made the arc? It seems that you started another thread with this question. Have you already tried the suggested solutions?
If they don't work post the SKP model here so we can have a look.

[quote="ely862me"]You don't need a plugin to close a face. If you use the Line tool as advised you will close the open faces, but the old faces will still be there. Then you have to select the old faces and delete them.

The easiest way for your geometry should be this: Select Push&Pull Tool, pull one side of the opening to the other side, then press the Space bar key and with your mouse select the remaining top geometry and delete it by pressing the Delete key.

thanks ! it works.
one question more.

If the surface is planar, just draw a segment like the picture below.
