What is your approach to CAD learning?

I have been interested in CAD and Design. Recently I am learning AutoCad and Inventor. My goal is to learn Autocad fluently in the shortest time when I can get a job. Anyone have any suggestion learning quickly? i am already making flash cards, have lynda.com and plural-sight subscriptions.

FredSWUG and DHANASEKAR VINAYAGAMOORTHY have it down right of what you should do. I had to learn both softwares you mentioned in college and I use both at my job. It's good to do a mix of 2D and 3D. Not alot of places use AutoCAD for 3D modeling anymore. Rather they will use it purely for 2D and use other software like inventor and solidworks for their 3D. Alot of schools are now teaching 3D first and then showing the 2D so that students understand what 2D drawings will look like depending on the views you show in your drawings of the 3D objects. You can go that route or the classic 2D to 3D route. Video tutorials and tutorials that come with the softwares will surely help you learn what each software is capable of.

Flash cards for CAD? Those sound interesting, are they vocabulary terms? Can you give a few examples?

Video based sites are helpful, but be careful. Some "tutorials" may make use of practices which look OK, but thinking that is the way to do something, and learning it can make it difficult to re-learn a better/correct way latter. Sadly there is nothing outside of experience which will alert you to these issues.

I think the best advice is to simply build things in the CAD software. What to build is really dependent on the type of work you may obtain. 2D to 3D conversions. Reverse engineering from physical object to CAD model. Blocky prismatic models vs. swoopy industrial designer stuff. Parts vs. assemblies...
There are many possible paths.

You may also discover that your employer is making use of different software from what you learned on, so learning how to design is more important than pressing buttons in a program.

How to design requires knowledge of how the product will be used and manufactured. Injection molding, blow molding, casting, machining, forging, vacuum forming, 3D printing... etc. Knowing the costs, limits, and capabilities of manufacturing, tolerances, and materials will be just as valuable as skills in a CAD program.

Dear Rahman Amir,

It's easy to learn CAD once if you are good in using tools( best practices) soi prefer you to learn by examples (i.e) instead of learning tools try to practice some example say shaft in which you will come across various tools.

To know about modeling softwares follow my tutorials or video tutorial for learning purpose

Learn to design. CAD is the proverbial paintbrush in the artisan's hand.

Learning is doing so... model often. Find a good modeler and dissect his/her work. Roll back through build trees and look for the logic in the build process. It should be somewhat evident.

As many have already said... and if I repeat it's not for any effort other than to reiterate for importance... there is a lot of information out there. And, some of it is actually good. Sadly enough, most of the lessons/tutorials I've seen from universities has not been, and I have a few guesses as to why but I'll leave it at that...

As stated, there are so many disciplines of design... it might help if you specified which are of most interest to you. In the end, learning is doing but doing can lead to lots of bad habits too. Most of which will be ironed out of you in short fashion once/if you start working with a group of designers in a collaborate effort... That said, nothing much compares to OTJ training...

Hi Amir,
Just follow the tutorials you have and do practice lot....Then you will be an expert within short period of time...
