    Default TIN lines cross feature lines

    I thought that NOT having that happen was one of the points of feature lines? Yet i've got a surface where the tin lines from the back of sidewalk run straight through the feature lines for the front of the sidewalk, and the edge of pavement below.

    Any ideas on what's going on? All the feature lies are on the same Site...

    Not sure; are you adding the Site's Feature Lines en-mass (right clicking the FL node under Site) or are you selecting some in model space, adding to Surface as Breaklines, then others as you go?

    If the former, try removing that named set of Breaklines, rebuild the Surface (without them), then add them back; just double check that the operation order in Surface definition is correct.

    HI
    Which order did you put them into the surface. I've had times where I put in the breaklines then the points where it overrode the breaklines. I alway put in the breaklines last then they trump everything.

    That dwg file began behaving in increasingly bizarre ways, giant holes suddenly opened up in the middle of the surface for no apparent reason (and I mean giant -- like 30% of the surface became a hole). Final result was to delete the surface completely, and re-create it from the feature lines in the file. That got me out of the hole (??) It was falling into.

    I've also seen surfaces with a lot (±200) "Edits", that all of a sudden started ignoring certain feature lines.
