is it possible to combine more than 2 surfaces, say corridors to your main grading surface?

Hi and thanks a lot for this valuable tutorial, but I have a problem. When I export only centerline, the .geo file is created, but when I export centerline and banks, it shows an error following: Undo failed for class: aecc_alignment, and it doesn't create .geo file. Can you help me with how I can solve this problem please? I need your help so much. Thank you

Great 7 part series, sir. Much appreciated. Thank you for your time and effort.

Thank you for this simple and straightforward tutorial. As a new HECRAS user I feel like other videos have been overwhelming with information but this was to the point and simple in an informative way.

Thanks

Sometimes curb return alignment is not tangent, there will be a gap to form a corridor. Do you have any idea to solve this matter? Thanks!

Thanks John. You helped a lot!

Very helpful, will you able to do a roundabout design in Civil 3D 2024

Thank you John for this

Your instruction / guide is very helpful! Only comment I have is if you are copying and pasting from one file to another for those tin surfaces to select the base tin (your "DEM Surface" here) and copy to clipboard. In the combined drawing file, I right clicked and pasted to original coordinates. Since I geolocate everything, it aligned perfectly. @ekelwantsfood this may help you

Really appreciate this video. Another way to accomplish this would be to: 1. Click Annotation Tab 2. Click Add Labels drop-down arrow. 3. And then select add multiple segment line/curve labels 4. Select the Polyline or lines

Hi I need a. Job, where I can contact you?

I followed the Video...but at 11:15, when I export, there's a lag, and the .geo file is made of 0 size in my directory I pathed to. And subsequently, when I import it into the HecRas geometry file, there's nothing there. I did a dwg audit, nothing needed fixed, restarted 2023 c3d and tried again....same result. The alignment & sections are there in c3d. There's a discontinuation at this export stage. Not sure what issue is of.

Thanks!

You are great man! Thanks for sharing, you saved me a lot of time!

Thanks!

Thanks sir for this exciting video. I have this challenge with SAGA Plugin Whenever I run Fill L &G, get error as SAGA 7 .2. 8 is not a support for windows. What's the solution, please.

Hi John, Thanks very much for sharing this. I was wondering, how do you fix the sections intersecting each others like for example 799 and 666.54 in your example? Is there any way you can make a bend without necessarily cutting them in order to avoid them to intersect? (In the situation when you receive a survey I mean, so you have no surface to cut them from)

Thanks for the video! Starting to learn LAStools

Good job sir

thanks for sharing your precious knowledge with us

At 6:00 I would suggest using the FILTER command to bring the Elevation from the Object Data to the Elevation Property field.

6:00 - why wouldn't you isolate the contour layers? You should really learn that command. LAYISO

Very helpful!

bro this helped out so much with hydrology class. Not trying to offend anyone, but I'm glad there is someone with a good ole American accent speaking. Usually there is some guy from India or God knows where, and I can hardly make out a word. Bless their hearts

Hello John. I'm so happy I stumbled across your YT channel. I work for an Environmental Engineering company in Maryland. I've been employed here for over 15 yrs. I've become the unofficial in-house go-to person for all things CAD. We have a hard time finding videos that we can use that are extremely relatable because there aren't many companies making videos that do what we do. We do alot stream restorations, as well as SWM retrofits, dredging, and shoreline stabilization projects. So far, your videos have been some of the most useful for be to be able to tell a new hire to watch and it actually have practical applications here at our office.

THANK YOU SO MUCH JOHN!!! I had a problem where my vectorized raster can't make a proper Thiessen Polygon. Your video helped me to check in the attribute table and made me realized that there were 30 polygons :')

Hi. Im unable to paste dem. how did you do that?

Thank you for a very helpful series!

Thanks for the video! When I imported the .geo file I got the following error: "None of the XS's are Geo-referenced". How can I fix it? I have set the projection in Civil 3D via adesetcrdsys command. Any idea?

When I import my polyline banks from Civil3D, the geometry bank stations are shifted to the left of my river centerline. Do you have any ideas as to why this may be happening?

Hi John. Thanks for the video. However, when I convert my raster, it doesn't multiply the values by the full 3.28083. I expanded the number of digits in the units under general project settings, but no luck. Any thoughts? Thanks again.

Hi John, thank you for your detailed tutorial. Under "Culvert Summary Table", there are "Inlet Control Depth" and "Outlet Control Depth". I wonder how to interpret them? What do they mean and how can we use them? Why do we have 2 depths here? Thanks.

pls send this map to training on it

Good day! How can one find morphometric parameters like stream length , bifurcation ratio of this watershed using QGIS?

REALLY LIKE THIS BECAUSE YOU JUST SHOWED HOW YOU CAN USE RASTER IMAGE IN TO A VALUABLE TECHNICAL DOCUMENT. I WILL BE WATCHING YOUR VEDIO. LOVE IT.

OK I have a question, my DEM file has a .DEM extension not .tif. How did you download a .dem and get to .tif?

good stuff thanks

The way to tag the contour with its actual elevation is to run a query and link the elevation of the feature to the elevation provided from the shape file.

Good tip on the quick map services.

Thanks John, for the tips and tutorials. This is very helpfull, especially for a beginner like me.

Hi, are there any other softwares that can be used to create the hecras geometry? Thanks.

good job, need how to make document of the work (verification of work) as you said everybody make a mistake

good video

While going for the upslope area an error occurs stating missing / wrong parameter value..no idea!!

thanks for the video, great help

Great series John it helped me immensely. Do you think you can make a new series on modeling canal/river flow and possibly the hydraulic structures associated with it (i.e. Drop/outlet/culvert structures)? I think that would be a great series, also I need help with that haha. Thanks

Excellent tutorial

Thanks for saving my time, it really helped a lot.
