I'm running C3D 2008... I have a proposed surface that was created with
feature lines, somehow the feature lines have disappeared and when I rebuild
my surface, it turns to junk.
Try an Audit command first. I have encountered this with grading on numerous occasions. I usually try and have a grading file seperate from the design file to fall back on when my surface creation goes bad, cause it will happen. Sometimes an audit will get some my grading back so try that first. Also, double check your display tab, within the feature line style you are using, to make sure the layer is not turned off.
I have ran into this a few times. Never heard back from Autodesk Development....never got my feature lines back... if you search the forums there are some posts about it.
When I do significant grading with feature lines I like to make incremental saves so i can fall back to yesterday evening or w/e. Vault is definately worth while if this happens more then a few times.
If you haven't yet saved the drawing since rebuilding the surface, you can
export the surface out to LandXML, then re-import it, with the import source
objects on, and you can at least recover the geometry.

I have had that happen a couple of times - don't know why and I can not reproduce it.
A couple of surface items that might come in handy is to use either of the following:
Surface Snapshots: Freezes the surface build to that point. Useless if you change anything under that snapshot during editting but if a feature line disappears, the data was captured in the snapshot.
Copy Dependent data - this is a surface setting that will copy surface data into a surface definition if removed from the drawing.

For the past 2-3 weeks I have been trying to Phone Tutor an associate using
3D and he had this to happen over the weekend. I must say that as much as I
preached to him about keeping Feature Lines on separate sites, he had
located them on a site with several alignments. Needless to say, it was a
mess when we tried to move the feature lines to a different site. 3D did
not like it to the point that the FLs became "waferware". (La Poof and the
feature lines were history.)

Almost Exactly is what wfb said. I have had this happen numerous times and I FINALLY figured out where they were going. For some reason, when the feature lines were created, they were put on a site that was of no use to us. I then proceeded to delete these "useless" sites, and did not realize feature lines were in one of them. The stupid thing is, feature lines do not show up in a site with a little "+", unlike alignments, parcels and the other ones. So be careful, make sure to check the feature line section when deleting a site.
