Upcoming Webcast with Dana: Corridors for Channels, Ponds and Streams


I’m getting excited!  Next Friday, February 2, I will be leading the Civil 3D Friday Webcast with the topic Alternative Uses for Corridor Models: Channels, Streams, and Ponds.

I will be definitely showing a simple channel, a complex stream (like the one posted here) and a typical pond.  I would love your suggestions and questions ahead of time as comments here on civil3d.com so that I can better prepare.

If you aren’t familiar with the Friday Webcasts, now is a great time to get in the habit of watching them live.  They don’t require anything special, just a high speed connection to watch the screencast and a telephone to call in for the audio portion.

You do need to register ahead of time- it just takes a second and doesn’t cost a thing.  You’ll get a reminder email with instructions on how to login- so drop it into your Outlook calendar!

Alternative Uses for Corridor Models: Channels, Streams, and Ponds with Dana Breig Probert

On Friday, February 2, 2007 from Noon to 1PM (EST)

Sign up for Webcast: Alternative Uses for Corridor Models: Channels, Streams, and Ponds

And the best part?  I happen to be in Manchester that day, so it will be live from the studio!  I don’t know if there is a big audience like on Oprah or anything, but maybe at least I will have a few hecklers.

I want to see you there! (Or at least that little person icon on the side of the screen that represents you)

    Hi Dana,
    I often create surface models from bathymetry inside ocean inlets and waterways. A typical task would be to design a cut channel for navigation using typical criteria such as 1,000’x100′(feature line), cut to elev such as -12.0′ NAVD. Side slope vertical (none). The sand walls slough off to a natural slope eventually but is not controled (as usally done with land equipment). Regardless, I am asked to calculate volumes as if the slope was close to 0. This is a very typical project in the coastal engineering world.

    The questions is: How do you create a channel with near vertical side slopes and still taper it to existing surface on the ends (end of design channel)?

    Hello I have a few channel questions. I have a very simple channel that I can not get to contour right.

    I have a 10’ flat bottom channel with 3:1 side slopes going to daylight. I created a profile, alignment and a section for this channel. The depth of the channel varies. I have had problems making this channel daylight because it has angles along the alignment.

    The channel contours will daylight fine on one side but not on the others side when the corridor overlaps on its self at an angle it will not daylight. (Inside angel)

    So here are my questions.

    1.How can I get my channel contours to daylight properly?
    2.When using sections what is the best section to use when you channel varies in depth. (I had a hard time coming up with a section to use, none of the ones in tool palettes would work well if the channel depth varied).

    I even talked to Tec support about these problems and they could not help me.

    If you could help me or need more information please let me know.
