I am stil looking for a Free CAD / MDT. i have no interest in paying money
I would suggest you learn from some YouTube Tutorials for free CADs, the reason I say that is because it takes a lot of work/labor to create them and people would want something in return for them. In this case it would be a payment of currency.
Here at The Cad Company WE DO FREE CADs, we also have the option for people to buy our top range CADs but the FREE CADs are also to a superb standard. Join and make a ticket: https://discord.gg/czz36F2
