# Group Clashes by Properties

The following steps will show you how to group clashes using properties in Navisworks.

# STEP 1:

In the Selection Tree and Properties dialogue review which Read Level contains the information you need for grouping your clashes.

# STEP 2:

Go to Standard tools in iConstruct panel and run the Clash Manager tool.

# STEP 3:

Click the Options icon in the dialogue.

# STEP 4:

Go to Data tab and set CR 1 Property Read Level and CR 2 Property Read Level. Click OK.

# NOTE: Checkbox at Enable Subnode Comments allows the tool to check for the properties in lower levels (0 in this case) if not found in defined one.

# STEP 5:

Click on the Column Chooser tool in the Clash Manager ribbon.

# STEP 6:

Drag and drop selected property from Column Chooser to the tree structure in Clash Manager dialogue.

# NOTE: In the Column Chooser you will find all the properties in the Navisworks model.CR1 are the properties from Selection A model (Structural in our case) and CR2 are from Selection B model in Clash Detective (HVAC in our case).

# STEP 7:

Once your grouping layout is set, click on Save icon in the Clash Manager ribbon, give your Layout a name and Save.

# Note: Saved layouts can later be reused with other clash tests and models as well as used in BIMflow. You can switch between different pre-saved layouts from the drop-down menu. To switch between Layouts, at least two are required.

# STEP 8:

To push defined grouping back into Clash Detective select desired grouping level (Test Name: Structural vs HVAC in our example) and click on the Create Clash Detective Group icon in the ribbon.
