Missing Break Link option

It seems that it is no longer possible to break links on sketch items created when the face of a body is used to create the sketch.

I find that it's very hard to design around invisible lines that can't be modified. Was there some compelling reason for the change. If so, can it be un-compelled?

It looks like this is auto-projected and unfortunately these elements are "hidden" and don't behave like "normal" projected lines. I've turned these auto project options off in the preferences years ago.

I use the sketch project only on those items that I really want projected to keep sketches light and with those
"hand" projected sketch objects you can still break the link.

You can simply delete the auto projected stuff and "hand" project the entire profile if you actually need all of it.

In addition to turning off Auto-project as suggested by @TrippyLighting and only Projecting what you need - you can then select the projection glyph and delete or right click to Break Link to the original geometry.

@etfrench - interesting... That does look like a bug to me. I can't say for sure if it is a regression, because I can't remember ever wanting to Break Link on one of these auto-projected edges. But, you could well be right. I'll have the dev team look into it.

Any progress on this? I also have a projected sketch that I'd like to break the link off the original geometry.

To give you some perspective as to why. I downloaded an object from the internet and projected in the geometry into 2 new sketches. 1 sketch I have projected geometry that I wish to keep the same size. The other sketch contains projected geometry that I want to reduce the size of because it's too big and I want to scale it down but not have to redraw it all. Hence why I'd like to remove the link but keep the geometry.

no, no update. The workaround is to disable the "auto project geometry on active sketch plane" option, and manually project the face into the sketch. Then, you can break link, and scale/edit the geometry.

Hi @jeff_strater ,

Yes, this works. Turning off that feature in the preferences breaks the link. I had spline objects referenced so when it broke it added a bunch more splines but eh, that's what happens with spline objects.

I did find a workaround for my own issue which was that since I separated each piece into it's own separate sketch I was able to just hit scale, then select the sketch. Fusion was able to still scale down the objects without scaling the other parts since they were on another sketch! 🙂
