Hi I got 2 questions.

ok first I would like to know the lines of copyright. I notice people making 3d models of like gm cars ect and put it in there games yet I asked many game makers that do this in there games would this be a copyright infringement??? They told me that GM can't sue unless you use the logo on the car so if you make a car that is a 3d model that dosen't have the GM logo then it's not a copyright infringement. There is also others that say that even if you do use the GM logo you didn't infringe the copyrights since your the one that created the 3d model.

So if I were to make 3d models of gm cars with the GM logo would this be a copyright infringement??

My second question is about taxes is there any good book that can help me understand tax laws for personal and also commercial meaning corporates.

I did took a tax course which was 8 week course but the teacher didn't help at all so I do have a book but having trouble with it.. I am looking for guides like federal tax for dummys or somthing that could help me out.

Any suggestions of good books that could help me understand the concepts of the tax system.

Some students in my class said they bought a tax for dummies book which help a little.
