I have several ideas and want to design some physical products ? How can I go about creating or modeling these without spending money on costly software such as AutoDesk/AutoCad etc ?
Here is basically what I want :
1) Draw the object in 3D - physical design
2) Model and simulate it. Example aerodynamic modelling
3) I need the design software to be flexible since many changes may be necessary before finalization.
I am familiar with circuit design and simulation but not with physical things.
Also, any advice from people who've been involved with product prototyping, design and development ?
Thanks!
Update: Ok, I found FreeCAD and freeCAD, thats a start. My further question is, is there anything available for aerodynamic modelling ?
