    CAD for desining rockets

    Hello. I have a lot of experience designing rockets in open rocket. However, I want to move on to a CAD program like grab cad or solidworks for rockets. I plan to 3-D print some. What are the best programs, and would I still have to model them for stability and aerodynamics in open rocket? Thanks.

    How many of you CAD your rocket?

    I always CAD all my rockets before I start building in F360. Just wondering, how many of you do this?

    Tips and Guidelines for Aerodynamic Stability?

    I've been designing a simple one stage rocket with OpenRocket, which allows the user to design and simulate their designs. I was always told that a general rule of thumb for a rockets stability is that the center of gravity should be 1-2 calibers above the center of pressure. With this rule...
