    I am hoping that someone on here that is more familiar with Wildfire 2 than
    myself can help me out with a Swept Blend issue I have encountered. Here's
    the full story. I created a surface model in 2000-i2 that had a cupped up
    beam feature(Advanced-Swept Blend-Surface) in it. Try to picture a feature
    that resembles half a tube tapered at about a 20 degree angle along its
    spine trajectory. The surface feature was defined by 4 sub-sections that
    were all derived from existing datum curve features via Use Edge
    functionality in Sketcher. I created the sub-section datum curve features by
    sketching their single arc entities on 'Make Datum' planes that were
    'Through' 'On Curve-Actual Length' datum point features and 'Normal' to the
    existing spine trajectory datum curve feature. This worked beautifully
    through 2001. I could modify the trajectory or sub-section datum curve
    features and the surface feature would update with respect to these changes.
    No problems whatsoever. Okay. I had a requirement last week for a similar
    part model, so I did a 'Save A Copy' on the above-described surface model in
    Wildfire 2. Opened it up and modified the datum curve features' dimension
    parameters for the new design requirement, and the Swept Blend surface
    feature did NOT update.

    Is there any way around this problem in Wildfire 2? Unless I am mistaken, an
    Extrude feature in WF 2 will allow the user to check off an option for
    making their section sketch associative to a pre-selected datum curve
    feature, or an internal section sketch that is non-associative. Or something
    similar to this. Regarding the Swept Blend in WF 2, I guess I'm just SOL
    regarding the utilization of existing datum curve features for my trajectory
    and sub-sections.

    Thanks to everyone for your time.

    This business with non-associativite geometry is new with Wildfire. I've wracked
    my brain trying to remember where I've run across it, what models, what
    circumstances. Because your mention of 'use edge' geometry being non-associative
    rang a bell. But no luck so far.

    Except, the help files say something suggestive about trimmed, use edge splines,
    mentioning that they look for and need some references to determine tangency. Have
    you tried redefining the use edge curves to nail them down, so to speak. Axes on
    the end points of underlying geometry, center lines and dimensions, maybe? Or, how
    about offset or projected curves instead of sketcher 'use edge'?

    Ahhh, it's always happy news when things fix themselves.
