AUTOCAD, SOLIDWORKS OR CATIA! still dont know which to study?

First, i'd like to let you know that there several engineering and architectural design software like AutoCAD, SOLIDWORKS, CATIA, ProE, Inventor and other great softwares.

confusion tends to set in when trying to decide on which of the above is best to study or maybe start with. so if you're finding it difficult to make that choice, then worry nomore.

see why engineers needs the knowledge of AutoCAD
First I'd like you to stay away from Catia. It's great software but from a more practical standpoint you are more likely to
find employment with a company that uses Solidworks
than a company that utilizes Catia.

Next... you can't go wrong with learning AutoCAD. At some
point in your career I can practically guarantee you'll use it
at least to an extent.

Solidworks vs Inventor... tough choice if we're talking long term, both have a bright future and really you can't go wrong learning either one.

The end solution to your worries: I'd learn AutoCAD as
well as either Solidworks or Inventor. You'll find that more
and more individuals are using multiple software products
to achieve their designs and the more programs you are
familiar with the better deliverable you'll be able to
produce (and the more marketable you'll be in your)
