Solidworks and autocad are completely different and do not have the same "principle" of drawing! But solidworks is for me the most intuitive and the easiest to get to grips with CAD software! After a week you won't want to go back!!!
For the test there is the student version which is almost not limited except for the mention "Student license which appears on the plans".
Attached is the download links (you have to register before but it goes fast)
As far as I'm concerned, I have the opposite path: I started on parametric 3D software and today I'm working on AUTOCAD
Inventor or solidworks are quite affordable for beginners. The graphical interfaces are neat and based on the window banners.
Regarding the drawing itself, parametric 3D is much more intuitive. The only difficulty will be to get used to the use of sketches to move to a volume thanks to the different functions such as extrusion or other ....
Autodesk offers easy downloads of its entire range of software for students, but there is also a trial version: http://www.autodesk.fr/products/autodesk-inventor-family/free-trial
Dassault also offers a trial version: http://www.solidworks.fr/sw/purchase/solidworks-trial.htm
On the other hand, for rendering, I don't know much about AutoCAD, but the software offered with SolidWorks, PhotoView 360 is only available from the Professional (or Premium) version.
But it's still quite limited and I find it a bit complex to handle.
To see the different options available with the versions, see this matrix:
I hope I have answered your questions, if you have any others, don't hesitate to open a new question.
Edit: as you can see in the matrix, the simulation (or structural analysis by finite elements) is only available with the Premium version, the most expensive.
@flegendre, I think your humor is not understood by others.... I drive in A4 quattro and I have solidworks premium lol
I did a test of autocad 3D on Mac (it was at the time the only software running on Apple) and I would say that I didn't manage to use it as I wanted. Not intuitive enough compared to solidworks that I used in my old company.
The most difficult thing to assimilate with parametric 3D software (whether CATIA, SW, SolidEdge or Inventor) is the notion of the link between functions, parts and assemblies, of parenthood.
For example, I'm thinking of the "drilling assistant" function which allows you to manage automatic repetitions afterwards but which visually does the same thing as a "material removal by extrusion" function.
I advise you to go through the integrated tutorials that give the right basics and above all to forget everything you know about Autocad to approach SW.
Compatibility is not guaranteed, but that doesn't mean it won't work!
SolidWorks kind of clears itself of bugs that can occur on devices they haven't tested, because they can't test everything either!
A little search on Google with the name of your board and SolidWorks, here is an excerpt of the first link (it's not very pleasant):
"I would recommend a GTX Titan unless you need lots of OpenGL performance. If you regularly run Maya, XSI, SolidWorks, or other pro OpenGL based applications, then you'll need to stick with a Quadro card."
For tutorials, there are some integrated into SW (go through the help).
They will allow you to acquire the basics, then you can move on to the others who, amha, will lose on points of "details".
For the graphics card, it depends on what you plan to do. If it's just modeling your kitchen to show mom, your card will be enough (maybe accepting a quality of treatment a little below what you know with a dedicated card). If it's to go further (semi-pro use), you'll be (very) quickly limited.
For the comparison between autocad and SW, it's a generational difference. It is especially when it comes to modifying the model that you feel the difference. I don't know the latest developments of Autocad on the subject but for me, Autocad is basically a 2D software that has evolved towards 3D. It is this 2D foundation that handicaps him. As a comparison, I'd rather go between MSDOS and Windows 3.1.
The graphics card I saw after a search that SW was better with a pro card, we'll see how it behaves with mine.
It's the other way around, I went from a quarto 5000 to the GTX Titan without regret for Autocad and my other GPU/CPU rendering software.
thanks for the info Lucas
For SW, the first difference I know (by name) is the 3D parametric that interests me and the possible connection of the parts to each other.
Knowing the 3D functions of autocad well, I hope that they will look the same and be intuitive as you indicate and that I would not be forced to go through paid training but that self-taught will be enough.
I suspect that you have to practice for it to come but I wanted to test the waters before...
In short, it will be worth this launch in this new interface and tame it;)
