Designing and engineering by yourself (without expensive CAD software)?

Designing and engineering by yourself (without expensive CAD software)?

Designing and engineering by yourself (without expensive CAD software)?

Hi all,

I'm a B.Sc. Mechanical Engineer (specialized in product design) and i have an idea for a potential product that i want to design and engineer.

I think that i have the skill set to make it at least to the first prototype, but I'm not sure how to approach the CAD modeling part.
Basically I'm not sure how i can design something privately (from home) without buying an expensive CAD software (i.e Solidworks, Fusion 360 etc.).

I know there are free CAD software but which one is best suited for the job (modeling plastic injection and metal parts).

So my question is where and how to start, can someone recommend a decent free CAD software? or any other suggestions.



Hope I've posted at the right forum wink.

RE: Designing and engineering by yourself (without expensive CAD software)?


Do you need full-blown parametric CAD? Take a look at Onshape.

QCAD and LibreCAD both are Free Software. These are not up to full, commercial mechanical design, but you can do design, and prepare drawings.

If you are willing to spend some money, there is BricsCAD and VariCAD. Both of these have some 3D capability.

Thanks for the help i'll check the software you mentioned.

White Paper - Addressing Tooling and Casting Requirements at the Design Stage
Several of the tooling and casting requirements of a part can be addressed at the design stage. If these requirements are not addressed at the design stage, lot of time is spent in design iteration when the design reaches the die caster. These design issues lead to increase in time and cost of production leading to delay in time to market and reduced profits for the organization. Download Now
