What is the best way to learn 3d?

First of all , Be passionate what you want learn ....

Here are some Tips 

1: Get use to 2d drawings in autocad if u are in to architectural or interior 3d visualizer 

2: understand about the views ( front, left right , perspective camera views etc...) 

3: modelling different types of objects if u focusing in architecture or interior  just try to develop all the models depends on what u are in to ..

4: The main part is texturing, lighting ,rendering & Animation give the main priority on that part in 3D

5: post production is the final part of your render out put  for that different software's like photoshop , after effects , premier pro , particle illusion , Depends on your field and purpose your job . get in to this deeply

6: After all learned try to work with the professional people who is really talented and that will make your out put of your work as professional way very fast

7: Tutorials , online classes,  do not leave any opportunity to learn in 3dsmax 

Hope my tips will help you guys who learn 3ds max in the first time ..

Thank You.

for me self learning and practice

Do practice on 3D developement software.

1st make a 3D image in your mind

1. Knowing the basic knowledge about design and manufacturing work(like projections, sheet size, all the maufacturing process.

2. intial working in 2D in auto cad imporves more imagination skill

3. what ever might be  the 3D tool start knowing the ICONS and uses, and start doing the 3D model where you will start USing that ICONS. 

TO STADY 3D YOU MUST CHOOSE THE PROGRAM THAT YOU NEED TO YOUR Employment,IN DECOR WE USE 3D MAXIN MULTYMEDIA WE USE CINEMA 4D SO MUCHIN MOVIE EFFECTS WE USE MAYAAFTER THAT YOU MUST TAKE COURSE IN THE PROGRAM THAT YOU CHOOSED TO UNDERSTAND THW WORKSPACE OF THE PROGRAM, IT WILL TAKE 1 MONTH.AFTER THAT YOU MUST DO TUTOURIALS EVERY DAY TO apply IT, DAY BY DAY YOU WILL UNDERSTAND THE PROGRAM AND YOUR NEEDS FROM IT, ONE YEAR ENOUGH TO BE PROFISSIONAL

 2. understand about the views ( front, left right , perspective camera views etc...) 

YouTube is the best teacher. There are plenty of tutorials available in the site. I would recommend you to start from an easy software - Solidedge. The features in this software is comparatively less. Once you're comfortable with this software, move to tougher softwares like Catia, Solidworks, Creo, Autodesk Inventor. The basics of all the softwares is the same. The way you use the commands, the availability of features differs.

The best way is to be self taught. You learn at your own pace and you never stop learning if you're motivated like I am. When I'm not working, I am always watching tutorials and VFX Breakdowns.

First of all, choose a good software to learn on that has all the features you will need in the future.  I don't recommend using simple, low-feature tools like Sketchup because you will quickly outgrow them and start over learning a new software.  If you want to create accurate 3D models for engineering, inventing, or high-accuracy simulations, try Inventor, Solidworks, Autocad, or Catia.  However, if you want to make models for movies, video games, and special effects, then choose 3DS Max, Maya, Modo, Cinema 4D, Blender, Rhino, or Lightwave.  These are complete packages that can do almost everything.

i tried this e-learning site with after effect motion graphics and i think it was better than many other methods to learn

especially if you have the passion
