    Hi Mike:

    The grid would be based on CL. At each interval we would label all three
    alignment's stationing relative to CL. If the left flowline is longest we
    would have something like:

    Example: at CL Sta. 12+00, we would have 12+00CL, 13+23 LT, 11+15 RT.

    The transition vertical elements; tangents, PVI's and VC, info in the
    Profile would be smart to allow labeling of true grades and stations based
    on each alignment's true length.

    Our roads are designed using the template tools, but we have no way of
    outputting the true grades of the transitions. Along these lines it would
    also be helpful if there were design tools to see the transition true slopes
    during the design process. We also need to see the road cross slope
    relationship to make sure we're maintaining our 2%-4% road crown cross slope
    criterion when the offset is constrained laterally, as in gutter design.

    Fred,

    Thanks, you've answered it. The labeiling of the true grades and stations
    (not the transposed grades) is the critical point, as I though - just wanted
    to make sure. As you may know, we have the "Superimpose" profile feature in
    LDD, but labeling is only with respect to the CL for which the profile
    belongs to. I can relate how tough it must be to label all of the info from
    the transposed profile grade lines. Stay tuned.

    Mike

    Michael,
    No we have not had the need to do that. We usually have a CL profile and
    work off of that forcing 3dpolys to get desired cross slopes or gutter flow.
    None of the local agencies around here require us to show profiles around
    the curbline and 3dpolys work great to achieve what we want. After we get
    the 3dpolys we just label the critical elevations.

    Mike,

    Yes I do know about the feature and it helps for attaching Profiles to
    Transitions.

    Yes, it's a tremendous amount of work to transpose all that information.
    I'll be on standby.

    Re: Call for Cul-de-sac Examples

    11-13-2003 10:38 PM in reply to: *Rogerson, Michael
    This is a great topic coming from Autodesk. I have seen the routines in
    the programs for years but didn't find any usefulness in then with our
    designs. Hopefully I can use them in the future.

    I have designed Cul-de-sacs using centerline stationing up to the curb
    returns at the start of the cul-de-sac then use LT/RT curb stationing to
    to a point equal distant from each curb return. I then make my
    alignment for the cul-de-sac run through the end of the cul-de-sac to
    the length equal to the ending station of the curb stationing. that
    reserves the distance in the profile. I create my profile and then trim
    my existing ground at the curb return then use a quickview of the curb
    returns to insert the natural ground of the LT and RT curb.

    for the profile we will usually fake in a vertical curve in at the end
    with the center of the VC at the end of the alignment then trim it out
    from beyond the end of the alignment. If I end up with split curbs then
    I just need to make sure the grade into the end of the alignment is the
    negative of the grade of the other curb at the end of the alignment.

    We have a document that explains our design for Autocad that I could send.

    Thanks David, I got the example - I defintely will have some questions as I
    walk throught he procedure, not an easy one - this will also be a great test
    to see of the profile features are up to the task.

    Mike,

    Our situation is similar to Fred's further down in this thread. We are required to show all 3 profiles. Left curb, CL and Right curb. They all must be fully annotated with actual lengths shown where curbs are not parallel with CL.

    Our CL profile actually always continues to the top of curb in the middle of the the large radius (back of cul-de-sac) where all the profiles end at an identical point.

    This method provides us the opportunity to control all the warping in the cul-de-sac with individual profiles and provide curb staking onsite.

    Hope this helps.

    Howdy Gene,

    Thanks, understand - a common need seems to be the
    ability to first plot, then annotate parallel and non-parallel offsets on the CL
    profile (or onto any profile for that matter). 

     

    The annotation of the non-parallel entities as
    superimposed on the CL profile needs a few things:

     

    1) Label true grades along the offset (not the
    grades as the appear in the CL profile)

     

    2) The abiliy to label stations along the
    offset (not the CL stations) on the CL profile.  These stations distances
    would be non-linear in the case where an offset was non-parallel, curved or
    bent.

     

    From you comments, I'm assuming that for design
    development, you would likely work with profiles for the offsets as well as the
    centerline.  But, for review and construction drawings, these would often
    all be represented on the CL profile?

     

    let me know if I'm not clear here, or
    off-base.  Thanks.

    Mike

    I know this is no easy task, but its what we have to do.

    As far as the 3 lines of the profile. You mention design development and construction drawings. Right now there is no difference. We use a custom app built on LDT to design all 3 lines of the profile simultaniously (each line gets its own horiz. alignment) then produce a single profile that shows all 3 lines separated vertically by a 100 grid. This profile gets externally referenced into our construction drawings for plots that are used for plan check and construction staking.

    If I understand what your suggesting is that 3 different profiles could be used to develop the design and then brought together as a representation on a single (CL) profile for construction drawings should work. In theory...

    Let me know if I miss understood.

    Hi Michael:

     

    We actually need the ability to design the
    transitions (gutter flowline usually) as "independent" alignments and profiles,
    but they need to have an intelligent cross slope relationship with CL. We need a
    flag or a display where we can see the cross slope left and right of crown
    at each CL station. 

     

    Now, people are designing all three profiles, and
    "hand checking" the crown cross slopes, which is very tedious and eats profit
    margins.

    Howdy Gene,

    Thanks, understand - a common need seems to be
    the ability to first plot, then annotate parallel and non-parallel offsets on
    the CL profile (or onto any profile for that matter). 

     

    The annotation of the non-parallel entities as
    superimposed on the CL profile needs a few things:

     

    1) Label true grades along the offset (not the
    grades as the appear in the CL profile)

     

    2) The abiliy to label stations along the
    offset (not the CL stations) on the CL profile.  These stations distances
    would be non-linear in the case where an offset was non-parallel, curved or
    bent.

     

    From you comments, I'm assuming that for design
    development, you would likely work with profiles for the offsets as well as
    the centerline.  But, for review and construction drawings, these would
    often all be represented on the CL profile?

     

    let me know if I'm not clear here, or
    off-base.  Thanks.

    Mike

    Mike,

    Our situation is similar to Fred's further down in this thread. We are
    required to show all 3 profiles. Left curb, CL and Right curb. They all must
    be fully annotated with actual lengths shown where curbs are not parallel
    with CL.

    Our CL profile actually always continues to the top of curb in the middle
    of the the large radius (back of cul-de-sac) where all the profiles end at
    an identical point.

    This method provides us the opportunity to control all the warping in the
    cul-de-sac with individual profiles and provide curb staking onsite.

    Hope this helps.
    Gene
