With the run active, use the pp quick connect fitting to connect 2 components relative to one another in a tube and pipe assembly prior to or after populating routes. You can connect a fitting , a conduit part , free route end, or normal Inventor part to another base component that exists inside or outside the active run. You can also connect fittings before placing in the graphics window from your project work space using Place Fitting or from the Content Center using AutoDrop.

Keep in mind that the free fitting must be in the active pipe run. The base fitting can be either in the active pipe run or another run. If the style is a butt weld style and gaps are set to display, a gap is automatically placed between the route components.

Connect to a base component
On the Model browser, double-click the pipe run.
On the ribbon, click Pipe Run tab Route panel Connect Fittings .
In the Connect Fittings dialog box, ensure Connect fittings is selected.
Click Free Fitting if not already selected.
On the graphics window, move the cursor over the free fitting, conduit part, free route end, or normal Inventor part.
Note: For constrained fittings, the cursor changes to a grounded symbol and indicates the fitting is not selectable.
Click to set the selection.
Click Base Fitting, and move the cursor over the base component.
When the needed connection is highlighted, click to set the connection.
Set the engagement option. If you select User Defined from the Engagement list, enter a distance value.
Click Apply or OK. or press ENTER.
If the free fitting is a free route end, the system automatically creates an auto route region to accomplish the connection. Otherwise, it is always positioned relative to the base fitting during updates and other operations.

Tip: After completing the connection, right-click the free fitting or component, and then select Edit Fitting Orientation. Use the command to edit the orientation and the connection point of the fitting.

Connect between an existing connection
On the Model browser, double-click the pipe run.
On the ribbon, click Pipe Run tab Route panel Connect Fittings .
In the Connect Fittings dialog box, click Insert fitting .
Click Free Fitting if not already selected.
In the graphics window, move the cursor over the free fitting to insert.
Note: For constrained fittings, the cursor changes to a grounded symbol and indicates the fitting is not selectable.
Click to set the selection.
Click Base Fittings, and move the cursor over one of the base components that is part of the existing connection.
When the needed connection is highlighted, click to set the connection.
Set the engagement option. If you select User Defined from the Engagement list, enter a distance value.
Highlight the connection for the base component at the opposite side of the free fitting, and click to set the connection.
Set the engagement option.
Click Apply or OK.
Tip: After completing the connection, right-click the free fitting or component, and then select Edit Fitting Orientation. Use the command to edit the orientation and the connection point of the fitting. You can also select multiple fittings and rotate them as a group.

Connect a fitting during placement
You can connect fittings directly to other components during AutoDrop or a fitting placement operation. The fitting attached to the cursor is always the free fitting so you need to specify a single base fitting or base fittings that make up an existing connection to complete the connection.

Activate the pipe run to receive the fitting.
Locate a conduit part or fitting from your project work space or Content Center.
The fitting preview appears attached to the cursor.

Right-click and select Connect Fitting.
Click the button to indicate the type of connection:
Click Connect fittings to connect the selected component to another component.
Click Insert fitting to connect the selected fitting between 2 base components that make up an existing connection.
A red vector indicates the direction of fitting connection.

Optionally, to change the connection point on the fitting, do either of the following:
Right-click and select Next Connection.
Press the space bar.
Right-click and select Select Orientation. Use the Select Other command to navigate to the connection point and click the green area to set the selection.
Tip: Fitting orientation can also be changed after placement by pressing the space bar or using the Select Orientation command on the context menu. If you use Select Orientation, ensure that the 3D Orthogonal Route tool is active.
Move the fitting adjacent to the component to connect, click to drop the fitting when the 2 connection points are coincident.
If inserting the fitting between existing fittings, repeat to set the connection for the base component at the opposite side of the free fitting.
Optionally, use the 3D Orthogonal Route tool displayed to edit the orientation.
Tip: If the 3D Orthogonal Route tool is not active, right-click the fitting, and select Edit Fitting Orientation.
Optionally, to place multiple occurrences, right-click and select Continue. Repeat Step 4 through Step 6.
Right-click in the graphics window and select Done.
Edit fitting connections for pipe runs
When you select a free fitting in the connection, you can edit the engagement. You can edit engagement for:

Connections between fittings, conduit parts, free route ends, and normal Inventor parts that were manually connected using the Connect Fittings command on the Pipe Run tab.
Fittings connected using the Connect Fitting command on the context menu during fitting placement
You can also delete such connections for further edit.

Activate the pipe run containing the fitting for which to edit the connections.
In the Model browser or graphics window, right-click the free fitting and select Edit Fitting Connections.
To edit the engagement for a connection, select the connection, and then select an engagement type from the Engagement list.
To edit the engagement for more connections, repeat Step 3.
To delete a connection, select the connection, and then click Delete.
Click OK.
