Making your own supports is easy. A support beam needs to have something to attach to on either end.



Footers: Footers are the concrete blocks embedded in the ground and the supports are attached to. To add footers, select the "Add Footer" tab and place them on the ground where you want the supports to touch the ground.



Rail Connectors: This is where the supports join to the track. Select the "Add Rail Connector" tab to add the connectors to the track.



Free Node: Free Nodes can be added in the air to connect a beam in the air as well. To add one, select the "Add Free Node" tab and place it where you want to add a beam.



To add a beam, select the "Add Beam" tab and left click on the start point of the beam, and drag it to the end point and let go. Adding a Beam Node is a simple way to attach another beam to a existing beam. To add one, select the "Add Beam Node" and click along the beam where you want it to be placed.



Flanges are the parts where beams join together using bolts. To add one, select the "Add Flange" option and click along the beam where you want the flange.
