Hi,
The most common reason that these errors are caused is because sometimes when fusion re-calculates everything it
comes across something it cannot resolve without some help. This can happen most often with sketches not being
fully constrained but can happen for other reasons.
The way to fix it is usually by clearing them one at a time in the order on the timeline they happen. If you right click
on the icon in the timeline and "edit" it but simply press ok without doing anything, this forces fusion to recalculate
just that operation. By clicking ok you are saying it is how you want it and this often clears the yellow warning flag.
Sometimes it does not clear it and you have to edit it and actually change something but with yellow ones just edit
and ok normally does the trick.
Once you have cleared the first yellow warning fusion will recalculate everything and sometimes other yellow
warnings disappear also because the error in the latest flag was the based on the error you just fixed. If you are
lucky this will also fix red error flags. If you still have red ones then again, fix them one at a time using the edit and
ok method to start with or make a change to make them work and they will clear.
Fusion does a great deal of calculations in the background. Sometimes the user will do something that is fairly
minor back in the timeline that will cause these kinds of errors down the timeline. It all comes down to fusion has to
make a choice based on what you did and the choice is not obvious to the software so it throws a yellow or red flag.
The forum usually recommends that you ALWAYS clear a flag as soon as you get it when modelling because any
error will compound and you will be less likely to lose work later. Always have a good foundation. This is also why
the forum recommends that all sketches are fully constrained and blue lines and lock icons tell you that. If a sketch
is not constrained then fusion may have to make a choice and this will throw a yellow flag later.
Cheers
Andrew
