Introduction

In IMPACT for Revit there is a new feature available that allows the user to map the Revit walls to IMPACT Double walls definitions. 

When mapping the Revit wall to an IMPACT Double wall definition, one needs to consider the layers in Revit wall , this being important for the program to recognize the IMPACT Element type.  

It is not mandatory to have defined the materials in the Revit wall in order to map it to an IMPACT Double wall definition, but as mentioned before it must contain the layers.

Revit Wall Type - this is the type and name of the Revit wall 

IMPACT Element Type - this is the type of the IMPACT Element that is recognized by the program considering the layers defined in the Revit wall

Width - this field is showing the information of the total width of the element

IMPACT Definition - this field is for selecting the IMPACT definition 

Description - this field is used if one wants to have a description of the IMPACT definition 

Create Definition - this option is used when the IMPACT definition doesn't exist in company standard and needs to be created

Example

In this section we will demonstrate two scenarios when mapping the Revit wall to an IMPACT Double wall definition - one scenario when the IMPACT Double wall definition already exists in the company standard and the other scenario when the IMPACT Double wall doesn't exist in the company standard and the definitions needs to be created. 

Map the Revit wall to an existing IMPACT Double wall definition

Considering that the Revit wall has already been drawn in project and that it contains layers, you can either start the element mapping by selecting the Revit wall first and then start the Map definitions command (in this way, if the project contains other Revit element types such as floors, columns, beams won't be shown in the Map definitions dialogue window) or by starting directly the Map definitions command. This is available for both scenarios. 

Once the Map definitions dialogue window pops up, select the IMPACT Element Type. In this case we will select the Double wall. After this is done, select the IMPACT Double wall definition that already exists in the company standard.

The IMPACT Double wall definition will be displayed as long as the width of the Revit wall matches with the IMPACT Double wall definition. IMPACT displays IMPACT Double Wall definitions from both Local or Common company standard. 

If the IMPACT Double wall definition already has a description, then it will be shown in the "Description" field. Otherwise, this needs to be added to the IMPACT Double wall definition before mapping. 

Finish the mapping by pressing on "Apply".

Map the Revit wall to a new IMPACT Double Wall definition

It is the same concept as when mapping the Revit wall to an existing IMPACT Double wall definition. The difference is that when mapping, the IMPACT Double wall definition needs to be created.

Select the Revit wall and start the Map definitions command. Once the Map definitions dialogue window is opened, select the IMPACT Element Type.

In IMPACT Definition drop down list won't be any IMPACT definition displayed so that needs to be created. Press on "New" to create the IMPACT Double Wall definition. Give a name to the definition name and if necessary add a description. Finish the mapping by pressing on "Apply".
