Default How To: Compound Components

A compound component is where you merge the properties of two simple database components together to create a third component, which you cannot save to the database. The attached files show an example of this. I have created a transition to use with Estes BT-50 and BT-60 tubes, and which has a 1" wide base on the BT-60 end. The shoulder for the transition is still available as it would be with any other.

The idea is relatively uncomplicated. Start with your transition. Go into the edit dialog for the transition, and click the "Shoulder" tab. Locate the "Length" for the end you are adding the extension to, and increase the value found here by the length of the extension. Change the name of the component to some descriptive identifyer, and add "Front" in parentheses. Make sure the Material is "Balsa" (or whichever material you want it to be). Close this dialog. The shoulder is now very long on the 2D and 3D display screens.

Now, add a 1" length of standard tubing (in this case, BT-60) to that end of the transition. Open up the editor dialog for that piece of tube, and locate the "Material" drop-down box. Change the type of material, and the part name to match that of the original cone section, but add "Rear" in parentheses. Close the dialog.

You now have the equivalent of a single-piece component.
