Some objects block your movement through a 3D model in walk mode (you cannot pass through them). Typical examples of blocking objects are walls and roofs.

Revizto stores a list of collision categories. Objects that have these categories block movement in all projects opened on your computer. You can view and edit the categories.

• Viewing collision categories
• Editing collision categories
• Updating the list of objects that block movement after upgrading to Revizto 5.5

Viewing collision categories

Revizto stores the files with collision categories in the following folders:

• Revizto 5.4 or earlier:

  C:\ProgramData\Vizerra\collisionCategories\

• Revizto 5.5 or later:

  <Revizto working folder>\.collisionCategories

These folders contain plain text files with lists of categories.

Editing collision categories

You can add, edit, and delete files with collision categories.

To edit files with collision categories:

1. Do one of the following:

   • If your Revizto version is 5.4 or earlier, open the following folder:

     C:\ProgramData\Vizerra\collisionCategories.

   • If your Revizto version is 5.5 or later, open the following folder:

     <Revizto working folder>\.collisionCategories

   If the folder is missing, create it.

2. Add, edit, or delete the files.

   • Category files are plain text files where each category is on a new line.

   • If the category names are not English, set the encoding to UTF-8.

   • The files can have any extension.

   We recommend that you create new files for your custom categories, as Revizto might overwrite IFC.list or Revit_<language name>.list.

   Example:

   IfcWall IfcRoof IfcWallStandardCase IfcSlab IfcStair

3. To apply the changes, update the affected models (export them from authoring tools or import them from files).

Updating the list of objects that block movement after upgrading to Revizto 5.5

In Revizto 5.5, the location of the list of objects that block movement changed. If you update Revizto from version 5.4 or earlier to version 5.5 or later, to preserve custom objects that block movement:

1. Install the new Revizto version.

2. Copy all files from C:\ProgramData\Vizerra\collisionCategories to <Revizto working folder>\.collisionCategories.

   If the target folder does not exist, create it.
