.Working with Invisible Walls.

All you need to know about invisible walls and how to use them
.
Invisible walls are a great feature in FloorPlan 3D. With invisible walls you can create complex
things like sunken rooms, rooms with vaulted ceilings, partial cathedral ceilings, enclosings under stairs, story and half houses, and much more. This page is set up in a question and answer format with pictures so that you can better understand how invisible walls work and what they do.
If you still have questions that weren't answered on this page, please feel free to e-mail me.

What are invisible walls?
Invisible walls are just what they sound like, walls that are invisible. They have all the same properties as normal walls but they can not be seen in 3D View or in a Photo Realistic Rendering.

How are invisible walls inserted?
Invisible walls can be inserted just like normal walls. Select invisible wall from the list and click the insert button. When joined together like the walls in a room you can create a floor and a ceiling without visible walls. You can also add a roof over them.

1. Three normal walls and one invisible wall joined together
2. Four invisible walls joined together
3. Four joined invisible walls, ceiling selected in 3D View and deleted
4. Four 1/8" tall invisible walls, roof inserted on top

Why do you usually insert invisible walls on a new floor level?
Although invisible walls are safe for the most part, there can be problems. Occasionally invisible walls will "react" with normal walls and roofs causing the program to crash. This can be prevented by inserting the invisible walls by themselves on a seperate floor level. Just go to Tools:Locations and click Add. Give the new floor level the same properties as the floor where you want to insert the invisible walls.

How do I divide the floor in a room into two parts with two different materials?
If you have a room with a floor that has carpet on one side and wood on the other, just insert an invisible wall down the middle. This will divide the floor into two parts.

Above is a room that has been divided into many parts using invisible walls. This allows each section of floor, ceiling, and wall to have it's own texture. The 3D View is shown on the left and the 2D View is shown on the right.

Why aren't my invisible walls creating a floor and roof?
Make sure that all the walls are connected. You can drag each wall to see if it is connected to the others then just go to Edit:Undo to return it to the normal position. Sometimes it can be hard to connect invisible walls. Instead of trying to get it exact, you might want to just overlap the walls then go back, select the access wall where it has overlapped and delete it.

The invisible walls in the picture at left were placed so that they
overlap. This ensures that they are connected. The numbers
represent clicks with the mouse, in order starting with 1 and ending
with 5. Once you have walls like in the picture just delete the
overlap areas (highlighted in red).
