Using the BIM Navigator

You can import BIM files, such as .ifc and .rvt files to your project and use various tools to modify them.

The BIM Navigator palette groups all tools necessary to import the BIM files and control the visibility of BIM entities in the graphics area.

You can:

• Import BIM files, such as .ifc and .rvt files.
• Control the access to a file. Unlocking the BIM file displays the file content in the graphics area.
• Control the visibility of the entities. You can show or hide entities and categories of entities from the BIM files that you imported in the current drawing.

To access the BIM Navigator palette:

• Do one of the following:
  • On the ribbon, click BIM > Palettes > Navigator.
  • On the menu, click BIM > Navigator.
  • Type BIMNavigator.

The BIM Navigator Palette

The BIM Navigator palette groups the tools necessary to work with the BIM files content.

To display the BIM files in the current drawing and start using them, you must import the files. Once you import the files, the palette contains the following sections:

• BIM Files. Displays the list of BIM files that you imported in the current drawing and informations about the specified file. Unlocking a file displays the content in the graphics area and lists the entities in the Entities section.
• Filters. Displays the filtering tools.
• Entities. Displays contents from each imported BIM file in a tree view grouped according to their category and type. The tree view lets you browse the BIM file entities. Clicking an entity or a category of entities in the tree view selects the entities in the graphics area.
• Drawings. Displays the drawings created from the BIM model grouped according to their type.

BIM Files Category

Displays all files that you imported in the drawing.

File Properties List

Displays all BIM files that you imported in the drawing. These file types are listed:

• .ifc files
• .rvt files
• .rfa files

Right-clicking a file displays the following options:

• Discipline. Lets you associate the BIM model file with the corresponding discipline tag.
• Delete. Deletes the BIM file from the list.
• Unload. Unloads the BIM file
• Reload from. Resets the path to the BIM file.

Imported file properties include the following:

• Model Name: Displays the file name.
• Visibility (Show or Hide): You can display only certain files in the graphics area. The button symbol indicates whether, in the graphics area, the drawing entities are shown or hidden. You can turn each file on or off independently.
  • Visible
  • Hidden
• Locked or Unlocked: You can protect files so the entities from the model cannot be changed. The locked state prevents unintentional modification. If a file is protected, you cannot change, add, or delete entities from the model. Change the status to unlocked if you want to work with entities from the model.
  • Locked
  • Unlocked
