I am a degree'd mechanical designer with a decade of experience: AMA

[OMDA]

Those of you doing product development may need some help. Especially when it comes to:

• Design - What are good ideas/practices?
• Analysis - What do I have to calculate to know my idea works?
• General questions - Things I've always wondered?

Industry background:
Aerospace - Aircraft design/analysis including spacecraft and airplanes
Other - Engine design (very specialized type but leaving that unspecified for now)
Current slow lane career - Not specifying at the moment
Design tool familiarity - Solidworks, Fusion360, Nastran/Patran, Ansys, Abaqus, Blender
Strong general programming experience with applications to product R&D.

If you don't want to tell people what you are doing, you can PM me if you are comfortable doing that and just want to ask a specific question.
Usually I can find a simplified way to calculate or solve something without resorting to a piece of software that costs $$$$.
