Placing a Hanger in Free Space

This task shows you how to place a hanger in free space.
After you place a hanger you must attach it to the surface. See Attaching a Hanger to learn how to do this.

The Hanger Placement dialog box that is explained here allows you to perform several functions. You do not need all of them to place a hanger, but all are explained in this task. 

NOTE: There is a command in the menubar - Insert > Place Object from Catalog, that can also be used to place parts. However, the command works differently from the normal Place Part command described in this task. The command Place Object from Catalog is meant to be used with parts that are not typed, and is normally used in spatial products like Plant Layout. If you use this command to place a part, it will not have the technology associated with a normal typed part, such as automatic object naming or resizing capability, nor will it be a unique reference. A typed part is one that has been assigned a class and sub-class in the feature dictionary.

When you place an object using this command, a unique reference will be created and placed in the CATTemp directory. The instance will not point to the catalog. If you want the instance to point to the catalog reference then you need to add a keyword to the family to which the part belongs. Add the following to the family, using the Catalog Editor:

  • Name - LoadType;
  • Type - String;
  • Default Value - SameReference.

To learn how to add a keyword see Creating a Catalog in the Component Catalog Editor user guide.



1. Click the Place Hanger button and select the In Space tab in the Hanger Placement dialog box that displays.


  • The Section Definition fields display only if there is a hanger selected in the Part Number field.
  • The Path Creation fields display only when the In Space, Parallel or Turn tab is selected, AND the value of the Instances field is more than 1, AND Offset is more than 0.
2. Click the Open Catalog Browser button (under the Part Number field) to display the Catalog Browser. Expand the entries to see the hangers available to you. For this exercise, select HGR-Trapeze_Adj. The Catalog Browser closes and the hanger you selected displays in the Part Number field.

3. If you want to narrow the choices available, you can use the filter function. To filter, click the Filter Parameters button under the Part Number field. The Filter Definition dialog box displays.

Select an attribute, click on the down arrow in the Value field and select a value. The value displays in the Override Value column. Click the Clear Value button if you want to remove it from the column.

4. You can use the buttons in the Create field to place the hanger.

Click the Place on Active Axis Plane ... button to place along the X, Y or Z axis. Select the required axis in the dialog box.

  The Place on Compass Plane... button is used in special circumstances. Normally when you place a hanger on a surface, you use the Place on Surface button described below. There may be circumstances, however, where you may want to use the compass for added flexibility in placement.

  Click the Place on Surface ... button to place the hanger at an indicated location. When you click this button, a white square accompanies your mouse pointer. Position this square at the location you want to place the hanger and click to place it.

5. In the Instances field, enter the number of instances of the hanger you want to place.
6. In the Offset field, enter the distance between each instance of the hanger.
7. Use the Section Definition portion to define the size of the hanger.

Click on the down arrow next to the Number of Tiers field and select a number.

Click on the buttons next to the Tier Width and Leg Length fields and select a value in the tables that display. Check the Use as Default checkbox to use these values as the default hanger size.

8. The Attach Downcomer button lets you attach selected hangers to the surface you have placed them on. All hangers placed during the current session are selected by default. See Attaching a Hanger for more information.
9. The Edit Parameters button lets you change the parameters of selected hangers. All hangers placed during the current session are selected by default. See Change the Parameters of a Part for more information.
10. The Flip Hanger function allows you to change the direction in which the tiers overhang. Clicking the Flip Hanger button changes the direction of overhang in the selected hanger(s) as shown in the image below.

11. The Translate/Rotate Hanger button places the compass on the hanger. Click on the arc of the compass and drag to rotate the hanger. You can also move the hanger along a line, the manipulation lines on a compass or surrounding box, for instance.

12. Click the Set Attributes button to assign values to attributes during hanger placement. A list of attributes and values displays in a box at the bottom of the Hanger Placement dialog box.


  • Attributes/Values display only when Part Type is a Rack.
  • The Set Attributes button is not active until you define the Instantiating Attributes. See Adding Instantiating Attributes.

Select an attribute in the Attribute column and the Select Option box displays.

Select a value from the list and the selected value displays in the Value column (in the first box). Repeat for each attribute and value.

13. Click at a location to place the hanger.
  Clicking the Reset Tab Page button resets all the fields in the dialog box.
14. You can create a lofted pathway without having to open the Systems Space Reservation application. Check the Create Path checkbox before you click Apply or OK to create the lofted pathway when the hangers are placed. See Systems Space Reservation documentation for more information about lofted pathways.
