			== Model Subassemblies or Subcomponents ==

			A number of users have asked about how to create subassemblies (subcomponents) in OpenRocket. Although OpenRocket does not currently support subassemblies directly, subassemblies can be modeled using OpenRocket's cut and paste feature, and the following example demonstrates how to this can be done.

	During the construction phase, component mass values are commonly updated to reflect actual measured component weights, rather than the values provided by OpenRocket. In addition, subassembly mass overrides can also be used to imitate the weight of adhesives and other elements used during construction. Ultimately, the goal is to have the total mass in OpenRocket be the same as the actual measured weight of the rocket. After accomplishing that, you may also need to add weight to adjust the rocket's center of gravity when larger motors are used.

	3. '''Add Construction Weight Adjustment''' -- When construction is complete, including the finish, weigh the '''''flight ready''''' rocket and measure its center of gravity from the tip of the rocket; ''flight ready means that ('''except for the motor''') the rocket could be placed on the pad and launched''. Then, add a mass component to the design (usually to the nose cone) with a mass equal to the difference between the estimated weight and the actual weight of the rocket. Once that is done, override the CG of the weight and move its distance from the tip of the rocket backward until the estimated CG matches the measured CG. <font color="red">[Required]</font color></br>		3.
