Hi,
I cannot more strongly recommend that the best way to learn Fusion is to start with the Fusion Documentation
that has a number of tutorials embedded within it. After this you should start on the self paced learning on the
Fusion learning area and follow this up with the Fusion YouTube videos and @TheCADWhisperer YouTube site.
Be a bit careful about what other YouTube videos you watch about Fusion as not everyone knows what they are
really doing. They might know A way to do something but it is not always the BEST way. Your workflow and how
you go about doing things is important.
These resources are all excellent and much better than any book for the reasons explained by @jhackney1972
There are also three RULES pinned to this forum for some guidance.
As stated in RULE 0, pick something you are interested in and start modelling it. If/when you have an issue, ask
a question on the Forum and upload the file for the Gurus to look at.
I had about five years of experience with AutoCAD before I started modelling with Fusion and this is the way I
learned to model. I am still learning and enjoying the process. I am no Guru but I have learned an enourmous
amount through them and by watching how they solve others problems in the Forum.
Cheers
Andrew
