Roughly 20 new engineers sign up with GrabCAD every day and it's always interesting to check out their profiles to see what are the different backgrounds and experiences people have. Today I noticed a new joiner, Mark Mason, who has been posting CAD video tutorials on his website http://mtm-cadtutorials.blogspot.com already since 2008. They're mainly CATIA based with some SolidWorks and Mastercam thrown in.
Here's a recent example:
This is quick demo that shows how to create a 3D sketch and use it for various purposes. In this case you don't need any fancy functions. Just simple and straight forward tools available to any CATIA user.
Welcome to GrabCAD, Mark :)
