CAD Tips for CNC Newbies

Starting out in CNC or needing to create CAD for someone else to cut parts for you, this video highlights some useful tips and things to look out for that may cause issues with the CAM software later on.
It is not a demonstration of any specific CAD package, it is filmed with a 2d CAD as example but the information is relevant to any CAD system, including 3D.

Thanks, John, Are you making more CAD videos, I've been wanting to get into CAD. I only have the free programs like fusion360 and free cad but I have no clue how to use them at the moment, How do you find the anomalies?

Not sure Graham, I'm a bit of a ludite in that I use only 2d CAD which isn't in favour with many. For what 90% cut on their machines it is the best option, just not sexy. I'm more than happy to talk about the one I use and or answer further questions on CAD.
FreeCad I personally think is an aboniation with all the different workbenches.
I have previously used Fusion360, it didn't suit how my mind works but I understand it isn't as free as it was.
I recently tested Alibre, I liked it but found that at the level of package I needed, I don't need anything high end, some basic features were missing, so I stopped testing.
If I can get my hands on PunchCAD to test, that one appears to operate how I do.
