Intersect with model issue

[JakeMM]

Hi,

I've been having a few issues with Sketchup Pro 8 in which the "intersect with model" command is not forming a closed rectangle.

For example, a model I'm currently working on has this issue on a square wall, that's 300mm thick. I've drawn a rectangle on this wall which has closed. I then push pull it in order to cut through. The push pull when done by co-ordinates to 300mm creates a double face and doesn't cut through the other side of the wall.

The push pull tool also won't automatically snap to the other side of the wall, but instead goes straight through it, creating a rectangle going further into the room. I then select the inside face of the wall and try "intersect with model" or even manually redraw the intersecting lines, but whatever I do, the rectangle will not close.

By using "Colour by Axis", I can see that all the lines are completely square.

Any idea's as to what is going on? And hopefully how to fix it!

Could you isolate the wall with the rectangle and post it as a SketchUp file so we can see exactly what's going on?
