Create Walls from Rooms

Task area Components + Interior Finish

You can use this tool to automatically create walls on the basis of rooms you have already defined. Allplan automatically scans the drawing files for adjoining rooms and creates a wall where the offset distance between rooms matches the thickness of one of the defined interior walls.

The Create Walls from Rooms tool is particularly useful when you have scanned in the plan of an existing building and have displayed and modified it using the tools in the As-completed Drawings task area. You may already have created rooms in order to calculate the floor area or analyze other data. If you now want to work with three-dimensional walls – simply use Create Walls from Rooms!

Rules for creating walls from rooms

• This tool cannot be applied multiple times to the same drawing file:
  The calculation automatically generates wall junctions, ignoring existing walls.
  It is therefore important that you define all the existing wall types when you begin.

To create walls based on existing rooms

• Create the rooms before you use this tool. If you enter the rooms as 2D data, place the documents in question in the background.
• The rooms can be in the active document and in documents open in edit mode.
• Measure the distances between the rooms so that you can enter the wall thickness of the interior wall types.

1. Click Create Walls from Rooms (How).
   

   Activate Create Walls from Rooms in one of the following ways

   • Actionbar:Role Architecture Task Elements Task area Components

   • Menu bar: Create Architecture Special: Walls, Openings, Components

   • Palette: Tools Create area in the following module(s):

   Special: Walls, Openings, Components

2. Click the Exterior Wall tab in the Properties.
3. Define properties and set up the height for the exterior wall.

   Note: Define only one exterior wall, as the system only uses the first exterior wall defined. Make sure that the distance between two rooms to be joined is not more than twice the thickness of the exterior wall.

4. Click the Interior Wall tab in the Properties.
5. The following options are available for defining the parameters of the interior walls:
   • Enter the Number of wall types.
   • Define all the other parameters and the height of each active interior wall type.
     You can switch between the wall types using Current wall type.

     Note: The system creates walls where the distance between parallel lines is within a specific tolerance range (i.e. the distance does not have to exactly match the thickness you defined). To find out how to calculate the wall thickness, see Calculating wall thickness.

6. Click OK to confirm.
7. Click the rooms.

   Tip: Right-clicking in the workspace twice selects all the rooms in the active documents.

   

   A 17.5-cm interior wall
   B Exterior wall with two layers
   C 15-cm interior wall
   (1) to (4) rooms

Tip: To create several walls of the same thickness but with different materials in a building, you can use Change Archit. Properties to change the materials of the walls later.
