I hope someone can help me with this because I'm at a loss. I drew up my floor plan and everything was fine. Now when I go back into it my first floor walls don't show up on the plan, but show up as dotted walls on my basement plan. I have my first floor project at 0 and my walls are also set to 0. Does someone have an answer for this? It's very frustrating. I've also checked my pens and the walls are set to use a black pen. This is the first time that I've come across this. When I use my section tool and my elevations the walls show up, but not on the floor plan. Thanks for any help.
You might check to see what the home story for the walls are. Make sure it is not your basement level. Sometimes if the wall at one time protruded down to the basement level it will retain the basement level as the home story.

Select the walls in the 3D window and set their home story to the first floor. Also check that their cut line pen is visible (in the pen set), and if they are not high enough to be cut, lower the FPCP (Document>FloorPlanCutPlane)
