Purple dots/lines why are they here and what do they mean?

[hectorkal]

This purple lines and dots just appeared, now i am really wondering why are they here and what should i do?

Turned of the auto project, made the first body into a component, but still pink lines. Usually i don't have these lines. 

Really want to know why they are there and how to get rid of them!

Purple is Projected.

To edit them, you have to break the link to the original.

If the second sketch has a dimension to the edge of the body, Fusion has projected that purple line in for the dimension to make sense.

Deleting the Purple line is ok, unless you get the yellow sketch icon, if that happens you can only undo and hide the sketch/s.

Might help.....

So is this something new? Never experienced before. Its confusing because i just started re doing this design when these purple lines appeared, but i have no idea what i did different.

I kind of see what you say; but i do not understand why i never saw it before (maybe a few times in more complex designs)

Now its like every time you draw a body and make a sketch on that body there are purple lines..

There are 2 separate Preferences, that involve Projections, 

sounds like you have got the project on sketch creation still turned on.

Not new, some of us just don’t turn either on, and User select when to Project.

Might help....

Do you mean those 2?

[davebYYPCU]

Yes, if turned on, they are what I though was happening. 

[hectorkal]

Yes, but i already turned them off, and this is still happening!

There are TWO settings for auto-projection.

The second one projects the whole face when you make a new sketch on that face.

The FIRST one is what is happening in your picture. You started a new sketch on the upper face of the extrusion. Then you drew a rectangle. While drawing the rectangle, you clicked very close to (or on) the edge of the extrusion, and Fusion assumed you were trying to reference that edge, so it auto-projected that edge into your new sketch.

Yeah but i turned them off, so it shouldnt happen- but it does still happen.

(Googled the issue before posting, this was the first thing i found.)

Anyway i (kind of) understand whats happening and i feel like it doesn't really matter.

Thx!

That does not work.

Okay.
