I am not a graphic designer!
But now, I am looking for a Windows-based software to help me in the easy drawing of sophisticated 3D illustrations in the field of biomedical engineering and biomedicine.
* The most important criteria for me are to be user-friendly, as well as to be easy to learn and work.
* Moreover, that would be great if systematic tutorial videos of this specific software will be available on the web (Lynda, Udemy, etc.) to learn how to design complex structures (DNA, blood vessels, etc.) and organs (lungs, heart, etc.).
I do appreciate your useful comments and wonderful suggestions in advance! especially those who have previous experiences in illustration of images in the field of Bioengineering.
