work on longitudinal section first, then cross section
if you have to fill more than one gap in a segment: don't click on each gap ! => left click and hold and drag over the gaps.
work on a level that is right for you, and never ever give up, great rewards will come! I got that when I was feeling very demotivated on the lightning tutorial. Got 4 right then one wrong, so many times. but now I am substantially more patient!
2 tips for me :Always overpainting for blackspill, then remove useless branches and find the right curves in 3D view ! It helps a lot to understand the shape
using Z plane for misalignement, you can find the good misaligned part easier
The tips to better at scout!
Sounds simple, but check all the planes
Was probably the single most helpful thing I have learned since I started tracing
ALWAYS verify your 2D trace in the 3D view. You'll very often find false piece to remove !
