Create Evacuation Tags

In Naviate Bimfire the only tags that are pre-set in the templates are EN ISO 7010:2020 symbols. To create local tags for each region follow the steps below. 

To create a tag that contains all the details and colours of the symbols, follow the steps below.

Both AutoCAD and Revit are necessary to complete the workflow.

1. In Revit, place and isolate the component which to create a tag from.
   

2. Export the view to DWG.
   
   The most important setting in DWG export is that colours specified in the view are exported. This means all colours from the symbol will be kept in their original RGB value and much easier to assign each hatch to new layers.

3. Open the exported DWG in AutoCAD (doesn't't work with DWG TrueView). Select the block symbol and explode it into hatches.  Write explode in command.
   

4. In AutoCAD, go to Layer Properties.
   

5. Create new layers for each colour. Name them after the colours, as in the RGB colours for each hatch, i.e. according to ISO 3864-1, 249-158-0 / 155-36-35 / 35-127-82 / 0-83-135.

   These are used to control the colours in Revit so the layer colours don't matter in AutoCAD.
   
   
   

6. Select corresponding hatches and move them to the new layers.

   

   Note: Change the color to by layer.
   Save the DWG.

    

7. Create a new tag, either from a new family template or just use an existing family. In this example, an existing family will be modified.

   In the project browser, right-click on a tag and edit.
   
   
   Note: the tag must be the same category as the symbol in the first step. In this case, it will be a Fire Alarm Device.

8. In Type properties, change the value in Fire_FamilyTagMapping.
   

9. In this example, ArrowLeftRight will be the GUID for this tag.
   

10. Import the DWG that was created in the beginning and that has been modified.
    

11. If necessary, turn on Reference Planes in the view via visibility/graphic override.
    

12. Scale down the symbol so it’s the right size in mm, if the symbol should be 7mm as paper size, scale the symbol down so it's 7mm tall. 
    Use the rescale tool found under Modify tab.
    

13. After rescaling, remove the old symbol and place the new ArrowLeftRight in the origin (the intersection of the reference planes)
    Save the file with a new name and load it into the project.
    

14. For the tool Tag Evacuation Symbols to work, both the symbol and the tag must have the same GUID on Fire_FamilyTagMapping.

    Write the same value on the Fire_FamilyTagMapping on the component that was just turned into a tag.

     

    

    Note:
    1. Fire_FamilyTagMapping should be a type parameter, and Data type set to: text

    2. Since the 2022 spring edition, it's been a project parameter. If there is no parameter, just open the family and add a text family parameter and reload into the project.
