3D cad learning

bobh:
I’m having a terrible time learning Alibre CAD and I’m thinking I need a very simple CAD program to learn the work flow and thought process of 3D work. I have 2 strikes against me, 20 years of autocad 2D habits to overcome and I’m 64 so learning is quite a bit harder. I’d like to use my MAC to learn on. Anyone have any suggestions? Bob.  :wallbang: :help:

Dave Otto:
There are at least a few of us here that use Alibre, what are you struggling with, maybe we can help?
Have you gone through any of the tutorials?

Dave

Jasonb:
Ask away here or on ME forum as there are quite a few of us there who use it and one of the Alibre staff is on hand to help too.

CI:
I learned Solidworks in 2012, and I was a long-time 2D Autocad user.
I thought that since I knew Autocad so well, then learning 3D modeling would be much easier.
Boy was I wrong.

I struggled with SW for I guess a year.
One problem was that there were no tutorials for designing model engines, and so no good examples that were close to what I needed to do.

Another problem was coming up with some sort of algorithm in my head as far as what it was I was suppose to be doing, and how I was suppose to be doing it.
Drawing with pencil and paper is easy.
Drawing on a computer in 2D mimics what is done with pencil and paper.
Modeling something in 3D has some unique analogies.

I will start a tutorial here, for those who want to learn 3D modeling.
During the year when I was trying to learn 3D modeling, I gave up in total frustration over and over again.
The curse words flowed profusely from my mouth like lava from an highly active volcano.

Bottom line; I never thought I would be able to learn 3D modeling.
Then I thought that if I did learn it, I would never be able to create a model of any significant complexity.
And I thought I was too old for learning new stuff.
I was wrong on every account.

Looking back, the endless options are what make it so complex.
In reality, I use about 5 general commands, over and over again, and I wonder what all the fuss was about.

I will try to start a tutorial tonight, and post it here.
I think you will find it much easier once you know the basic concepts.

Here is my latest 3D model.
Not that difficult to make this model, except for the window in the water hopper, that has been resisting completion.

Jasonb:
Pat, will that be just using the one program or your rather unique method of mixing two programs?

Your method is not how Alibre like many other programs are intended to be used so could end up confusing Bob more rather than helping.

Bob it would help to know if you are using the slightly stripped down Atom as that does not have all thefeatures so answers need to be tailored to that or the more advanced Pro or Expert options and also what version.
