Well the little bit I know I will share. But I don’t know what you mean by "modeling and Light designs." You said you like to design spaces so that would be Interior Design which has many variations within the carreer. If you want to be a 3D interior designer you will need to have a degree in it. In order to get to those specific courses though you will have to first take basic – then advanced graphic design courses in order to become familiar with the software used to design in all of those fields. For example. An architect will use "Autocad" or "Cad3" software to design a building as well as individual rooms/offices within the structure. It’s basically a software made for engineering and architectual creation.

But you can’t just jump into AutoCad because it’s a complicated program and you have to have an understanding of engineering and/or an architectual educational background. Someone who’s end result in this field would be taking other courses in conjunction to which I’m sure involves some Math.

In 3D Interior designing which is an extension or sub-field of Interior Design they use software to create the layout of the room as well as the furniture, appliances, etc. I don’t know the name of it but I know there is a special software for Interior Design. But again, in order to get to the courses that train you in these softwares you have to start with graphics and once you get past a few basic/advanced graphic design classes then you can go into specialty software classes. I just thought of a few that might be for this – it’s called "Autodesk" and "Studio" ? not sure.

At least that’s how they do it at my school. I’m a graphic artist and I see these classes in the semester schedules all the time and they all say – "Prerequisite must have completed advanced Photoshop or Illustrator, or InDesign courses with a grade of C or higher" My school has a 3D Design Software course program but I’m not sure what the software is called.And I was under the impression that the students taking these classes are wanting jobs in animation, film or the video gaming industry. And there are people who create these virtual tours of places on the internet. Those are the types of jobs that these 3D Software students are going for. Every year at the end of Winter semester they hold a Graphic Designers Party with all kinds of contests. The finale contest is always the 3D Software contest where they have 5-6 computers set up and these students have a timed assignment to create something in this 3D program.

What you should really be doing is talking to a counselor at your school (although sometimes they know less about the carreer fields then the student does…..) But someone at your school SHOULD know what plan of action you need to achieve your carreer goals.

You might try googling questions regarding the specific field – like ask "What software do I need to be a 3D Designer?" or "How to become a 3D Model designer? Ask it just like any other question – you will get much better results.
