I have defined a basement wall which is typical for our construction and includes an insulated wall beside the concrete wall. In this particular wall the concrete is 4' tall and the rest is framing. The interior wall is a few inches taller than the concrete wall. A problem arises when I insert a window into the exterior wall. Softplan is adding a "phantom" lintel and sill for the window above the interior wall (see the attached screen capture).

 

 

I tried to include the wall definition file but the forum won't let me so I am including a screen shoot of the definition too. 

 

You can see in the section drawing that Softplan is also adding a lintel to the exterior wall effectively doubling my material count in Softlist. Any suggestions on how to suppress the extra window framing short of drawing separate levels for the concrete wall and pony walls.

I would guess that the program is just making incorrect assumptions that any framed wall needs a header. 

 

Can you edit the opening and uncheck Header?

If I do that then the one I need disappears too.

I suppose you can draw it as a conventional wall sitting on top of a four foot basement wall.

Is the window part of a group of windows (unit openings)? I've found when I have windows ganged together I get headers below windows or inside like you show. Sometimes the program tries to do more than it should. We ought to have more control.

I draw the interior 2" x 4" wall as a separate wall. That way, it can be continuous as the foundation/knee wall usually has different steps.

The trick to hiding the header is to position it to "Underside of top plates" in framing options. It will then reference the top plates at the shorter wall. You will also have to increase the height of the rough opening of the window or the sill and cripples will be poking out of lower wall. If you use softlist you'll also have to deduct the additional header, as this doesn't remove the header, it is just hidden within the wall.

I think you hit the nail on the head. Sometime the simplest methods are best. I was over thinking it.
