What software pays out the best ?
The average solidworks designer makes 51000, average drafter in solidworks makes 44000. The average autodesk inventor makes 50,000. Catia is 49000. Go play around on indeed .com or salary .com and see what the average wage is in your area based off what you want to do (drafter , or designer, engineer), this will help you develop a better idea. Where I am currently soidworks jobs pay more but are hard to find, while autocad jobs are far more common and pay a bit lower. It is in my opinion that it is good for someone to learn a few of the them or specialize in one and at least be familiar in another, this way you have greater value and can communicate what you need to other cad users.
