Green Lines on Sketches Need clarification

[jeffescott]

The green lines seem to appear when the sketch has lost the projections.

Once the projection is reconnected it seems that a purple line (clean projection) is there along with the green line.

I have been manually deleting the green lines to clean up the sketch, but with a complicated projection, this does take some time, and often I just delete the whole sketch and redraw it.

So what is an accurate definition and name for the green lines?

How do I prevent them from happening?

How do I get rid of them (kind of like the drop down for removing yellow lines?

Fixed.  Locked in place, by Fusion on import of an external sketch, or redefined sketch.

(as you didn’t constrain them individually)

Do not import external sketches, or redefine sketches to a second location.

Window select them, and Delete / Unfix them (Padlock constraint toggles Fix / Unfix)

Might help…

You get green locked lines if you use redefine sketch plane on a sketch containing projections.. You should really try and avoid redefine sketch plane because it converts projected geometry to locked without warning and after that the sketch is no longer parametric and will not update. And the problem with deleting the green line then reprojecting is features downstream in the timeline will break and as you fix those it will tend to break more downstream features and it the end destroy your design!

If this is the problem you're seeing you should try to create an offset plane to sketch on if you think you might need to move the sketch plane. You can reattach a plane to a new feature without breaking any projections in sketches relying on the plane.

Thanks to both of you, nailed it I have been merrily creating chains of projections of several sketches, then redefining sketch planes.

Easy fix now.
