Hello
For those who use Fusion 360 or who can answer too 
Can you help me sort out some things.
1/ How to save an image of a rendering with a better resolution proposed?
2/ Glitch on the decal. I have a line behind I don't know what it is and I don't know how to remove it?
3 / How to create a new sketch from another, i.e. take and build on the previously created sketch
Thank you!
