I can't open your part, as I am still using SW 2010, so I could be way off base here.
Features usually disappear because you were rolled above it in the feature manager and deleted a feature that it was a child to. That would also match up with the sketch losing its external references, leading to the ->?
The Sweep features are grayed out until you exit out of the sketches. Just another peculiarity of the program.
I am working with this part and suddenly, the boss-revolve disapears
I have no idea why the feature disappeared. It may have been a SW glitch or (more likely) something you did, or didn't do.
But what means this adding of ->?, why the boss-revolve suddenly disppeared ?
Delete the DefinedInContext > Coincident4->? relation in Sketch1->? and you may be happy again ... for a few seconds.
The story don't end here : I want to make a sweep-cut, with sketch2 as profile, the Helix as path : I can't get the sweep option, in the list of cut features.
The Swept Cut tool is greyed out because you have hidden the solid body from which the cut is to made. Show the sold body and the tool becomes available.
FYI, it is usually good practice to fully define sketches, and it is always good practice in a Swept feature to use a Pierce constraint between the Path and Profile.
And tx for the help.
Since yesterday, I saw that an hidden body make the swept cut out of the list.
As there was also an ->? added in the name of the sketch, I thought yesterday that the 2 things were binded with some cast.
Today I also got some ->?, and an icon of boss-extrude sketch with a scroll being pierced by Sauron's finger.
I don't know what is such magic, but I go on toward the Mordor.
Can you show us a screen dump of the icon of the boss-extrude sketch. Your description, though quite evocative, doesn't remind me of any icons I can remember. Of course, I may not know what I am seeing when I see the icon either!
Jerry, the feature was just appended with ->?
The state of external references is displayed as follows:
- If a part or feature has an external reference, its name is followed by –>. The name of any feature with external references is also followed by –>.
- If an external reference is currently out of context, the feature name and the part name are followed by ->?.
- The suffix ->* means that the reference is locked.
- The suffix ->x means that the reference is broken.
Tx for your infos.
Really a big of SW is that SW don't list what could be broken, or where a missing relation is needed.
The mate feature lists a missing line or plane, but that don't occurs everywhere.
Or i didn't see where this info is displayed for the sketch
Since I am still stuck on SW 2010 I can't open the file to see the icon. One possibility is the icon for sketches with multiple contours. That appears to have a hole in the middle of a scroll. I would put up a screen dump, but my system is not behaving well right now. I think I need to reboot.
