Double Wall definitions are used everytime the user draws a Double wall element. You can either use already existing definition from the IMPACT database or create one in your own. In order to see all Double wall definitions, go to IMPACT tab -> Double Wall as shown on the picture below.

The Double Wall definition dialog consists of six tabs, where it is possible to set default values for each definition. In this article, you will be presented to the basic settings in each definition tab. 

General

In the Geometry section, set width for panels 1, panel 2 and the element´s total width.

Material for panel 1 and panel 2 needs to be selected from the drop-down menu. Make sure that your IMPACT material is mapped to a Revit material. 

Endstop is a component that is widely used in Double wall elements. Select a default end stop for the double wall element or keep it empty if not necessary. The endstop IMPACT definition must be linked to a Revit family. See how to map an IMPACT CIM definition to Revit family here

The production line is a company setting that is created in the Standard Admin Tool, if necessary.

Lift and Bracing

Settings for the element´s lift and bracing can be made in the second tab in the definition dialog. 

Min. distance two lift points: The minimum distance is the distance between lifts if only one lift should be used. Set to 0 to ensures at least two lifts will be used.

Max. distance two lift points: If the distance between the lifts pases 4000 mm, then four lifts will be inserted on the element.

Select lifts and bracing in the appropriate drop-down menus.

It is possible to place bracing both on element elevation and long side.

Reinforcement

In the Reinforcement tab the user can set default values for Reinforcement bars in panel 1 (left) and panel 2 (right).

It is good to remember that all the reinforcement values are editable when drawing the elements (Draw Double Wall command) or when editing the element (Edit Double Wall command) during the design process.

Mesh

Default mesh definition is selected under Mesh tab and here it’s possible to set placing and cover.

Moreover, the user has a possibility to decide whether the the “outer” bars of the mesh should be placed vertically or horizontally by default.

Lattice Girder

Make settings for Lattice Girder placing in the Lattice Girder tab. 

Choose Lattice Girder definition and make sure that the IMPACT definition has a Revit family mapped. See how to map a CIM definition to Revit family here

Min. dist. from edge (mm):  Defines the minimum placement of the Lattice girder to the edge of the Double Wall

Max. dist. from edge (mm): Defines the maximum placement of the Lattice girder to the edge of the Double Wall

If the first girder can not maintain the minimum distance and the next one can, then the first girder will be deleted.
If the first girder can not maintain the minimum distance and the next girder can not too, then the girders will be kept on place as they are.

Spacing (mm): Choose a spacing from the drop-down menu. The spacing is defined by the Mesh settings. 

If the vertical bars of the Mesh are placed pr. 150 mm, then the user will have a possibility to place the Lattice Girder respectively pr. 150 mm, 300 mm, 450 mm and 600 mm. Take a look at the example below. 

Girders will be placed on top of the horizontal bars of the mesh. If panel 1 mesh is not available, then the girders will be placed on the horizontal reinforcement bars.

Naming

In the Naming tab, the user can make settings regarding the element recording in the IMPACT database. 

Element Group:  Read about element group settings in the article here.  

Element Product: Read about element product settings in the article here

Prefix designation: Read about prefix designation settings in the article here. 

Prefix element mark: Usually a couple of letters that indicate the element type. In the example below DW stands for Double Wall. 

Prefix element name: Usually a couple of letters that could be used as suffix in the element name in the shop drawing and the IMPACT  database.

If the value for Prefix element name is empty, then the Prefix element mark is used in the shop drawing name. According to the example below,  it will be DW01. If IMPACT finds a value in Prefix element name, for example ´´DW_´´, then the name of the shop drawing in the database will be recorded as DW_01
