Once you have created your ground floor exterior walls, adding more levels to your design is easy. You can draw the layout just like you did to create the ground floor, or you can use the Duplicate to Locations tool to copy the ground floor exterior walls to the second floor location.
To create a new story by drawing the walls:
Make sure the current location is the Second Floor location, or whatever location you have set up for the story you are creating.
Select Insert
> Walls, or click the Walls button on the Building toolbar.
In the catalog, select the wall type you want to insert.
Select a start point for the first wall.
Move your cursor in the direction you want your wall to run. Its length is shown as you draw the wall.
Note: By default, drawing is constrained to 15º angles. To release this constraint, turn off your Angle Snap.
When the wall is the length you want, click to set its endpoint. Your cursor will snap to the dimmed image of the walls below for ease.
To add another wall to the one you have just drawn, move the mouse in the direction you want the new wall to run. When it is the right length, click to set its endpoint.
When the wall layout is complete, right-click and select Finish.
To create a new story by duplicating walls on the ground floor:
Make sure the current location is the Ground Floor, or whatever location that contains the walls to copy.
Click one of the walls to copy, then Shift+click to select the remaining walls.
Right-click and select Duplicate to Locations, or select Edit > Modify Elements > Duplicate to Locations.
In the Duplicate to Locations dialog, select the Second Floor (or whatever location you are copying to).
Click OK. The walls are copied, and you now have a new story.
Note: When you copy a closed wall layout, a floor with the default material is automatically created on the location you are copying to.
