Note: You must have Fx3 Fp5 or higher in order to have the ability to articulate vehicles.
Step 1. - Drag onto your scene your desired truck and trailer
Step 2. - Select both the truck and the trailer by dragging the mouse around them both or click on each while holding the "SHIFT" key on the keyboard. Then select "Create Articulated System" from the actions panel
Step 3. - You new articulated system will appear over top of the original truck and trailer. Delete the originals and leave only the articulated system.
Step 4. - Select the articulated system then select "Edit Configuration" from the properties panel.
Step 5. - Click on the truck, you will see a blue diamond and a green circle appear. The blue diamond represents the point on the truck where the trailer is connected. IE: the pivot point of the articulated system with respect to the truck. Simply move this blue diamond (position using the center of the diamond) until it most accurately reflects the real world position that you are trying to recreate. The green circle represents the trucks pivot point and for most cases needs not be moved/altered.
Step 6. - Click on the trailer, you will see a red triangle and a green circle appear. The red triangle represents the point on the trailer where the truck is connected. IE: the pivot point of the articulated system with respect to the trailer. Simply move this red triangle (position using the right edge of the triangle) until it most accurately reflects the real world position that you are trying to recreate. The green circle represents the trailers pivot point and is generally near the center of the rear axial group.
Step 7. - Uncheck "Edit Configuration" in the properties panel.
Step 8. - Finished. You can now use your articulated system.
