r/civil3d

I’m a ME major who plans to graduate next May. I’m really interested in going into civil/hydrology/environmental so I am trying to supplement some of the relevant skills I’m lacking for that field. I would like to teach myself Civil3D and AutoCAD as those seem to be pretty common requirements for these jobs. What are some good websites/YouTube channels you would recommend to get a solid understanding of these programs? How familiar can I get with these programs without having any real job experience using them?

Dynamo Civil 3d 2027. Native nodes only. Lots of python scripts.

Civil Engineer. Mainly work on large scale subdivisions (60+ acres). I've worked for the same small firm since 2011 and handle all of our templates, Excel & CAD. I've been in between jobs for 6 weeks and I wanted to share what graphs I've built in Dynamo with the help of Gemini Pro.

Pipe Network

1. Insert profiles - Add alignments first. Click a point in the drawing where you want to generate every alignment profile view. Choose existing & proposed surfaces. Profile views all 45 ft in height with elevations being around the midpoint of where the profiles are.

2. Inverts & pipe sizes - import invert and pipe size data for a storm/sanitary pipe network from Excel. Automatically adjust sumps of all structures. Import HGL data from Excel for storm network. Import sanitary service data from Excel.

3. Network into Profiles - Insert pipe network in surface profile views. Referenced alignment parts are correctly drawn in the relevant profile, along with the lateral structure.

4. Crossings - draws in the pipe network crossing on the appropriate profile views, and updates the profile pipe style to a crossing pipe style. Output indicates how many crossing pipe are drawn.

5. Pipe descriptions - import storm pipe descriptions data from Excel. ie. Type B or C, class, concrete encased y/n.

6. Sanitary castings - Sets the given surface adjustment value of top of castings for all proposed structures in a pipe network. Ignores existing structures.

7. Renumber structures - Numerically renumber pipe network structures. For example, structure names 1, 1A, 2, 2A becomes 1, 2, 3, 4. Number takes precedence, then letters. Ignores existing structures.

8. Structure Quantity Takeoff - Generates QT structure report for a pipe network. Pipe quantities are generated directly in Excel, by size, phase, pipe type, concrete encased, class.

Plan Generation

1. Sample Lines - Generates sample lines for all alignments. Choose swath length. Sample lines are added at station beginning, every 50 feet, with 10 additional sample lines are the end of the alignment. Adds sample line style to all sample lines.

2. Template - Creates a new drawing based on the selection (street plan, storm, sanitary, grading, erosion & sediment control, water, intersection, dry utility). Depending on the plan selected, several things happen. A color translation happens first. We have our own in-house color scheme for each drawing type. This is applied to both the native layers and external reference drawings; Specific native layers are frozen; Specific styles reduced font size and/or change to a different layer within the style; The viewport in the layout tab shifts to the correct legend.

Grading Tools

1. Building pads - Updates pad elevations based on spatial distance around the pad. Targets feature lines on specific layer. Not perfect, but good for a one time use.

2. Corridor Low-High Points - Generates circles at all low and high points within selected corridor. Each have their own layer to easily distinguish. Not perfect - not every circle is an actual low/high point, but is a good illustration.

I think this is the best I can do with what native nodes are available in Dynamo Civil 3d 2027. Most external packages break in the 2027 edition and won't receive any updates. I would love to be able to import pipe length and structure elevation data into Excel but that node is still buggy. Hope this helps with engineers figuring out if Dynamo is worth your time. It is! Building these graphs save so much time on redundant and repetitive tasks and frees up more time for design.

I'm currently in the middle of importing a lot of my models into navisworks but I've found an issue with the display of some surfaces which I can't figure out.

I have created my final ground surface, using my EG and my corridor surface. However, when shown in navisworks my final surface and actual corridor model seem to clip with each other and I can see the ground triangulation come through in some areas. It doesn't give a clean display of the 2.

Is there any way I can stop this happening? I can only think of slightly raising the corridor model just for model purposes but ideally want to avoid messing with it.

has anyone had this happen to their drawings? I opened a drawing, and the viewport that i set earlier this month, the view shifted 2211399.7668 away. but another vp on the same page is correct. i fix it, purge, audit, save and close. but when i just opened it, it did it again. im about to flip a table. why?

I use Macbook Air and will need to use Civil 3D Software from next semester. I want to know if it is possible to use parallel software for that? And How civil 3d software works on parallel?

I have no idea how you guys do it, tried gaining permanent access to civil 3d but yet to succeed, only managed to exhaust my free trials over and over again.

Anyone with a solution? (Currently unemployed, and striving to learn and practice)

I am having an issue with alignment labels displaying skewed in paper space but in model space they're fine. I tried running the issue though ChatGPT and Claud with no luck, so I am hoping someone knows the solution to this.

Normal in Model Space

Skewed/Rotated in Paper Space

I should add that I did use View Frames to create the sheets so the viewports are rotated to the alignment, but that's the same with numerous other projects and this has never been an issue. I've tried changing the settings in the style that both AI's were suggesting and nothing works.

What makes CAD difficult sometimes is that there are 500 ways to do any one thing, and everybody thinks their way is the best. I find among people I talk to there's a surprisingly wide spread in how people use the built-in C3D features to manage points and linework. Wondering if there's any overall consensus.

For importing and managing points, do you:

1. Use the survey database 100%
2. Use the survey database, but then import points to the drawing as COGO points
3. Never use the database, import everything as COGO points and keep it that way

Do you keep points stored outside of the DWG?

1. Once I import to a DWG, that's where they live forever
2. They live in survey database
3. They live in the dwg, but I keep a separate CSV or TXT file alongside for backup
4. Something else?

For linework, do you:

1. Draw linework automatically from field codes as survey figures, then keep them as survey figures through production?
2. Draw linework automatically from field codes as survey figures, but then convert figures to 3D or 2D polys and draft from there?
3. Draw linework either by hand or some other way as 2D/3D polys and never touch survey figures?
4. What's a survey figure?

Bonus Question:

For boundaries, do you use parcels for every boundary line? Some of the time? None of the time?

Hi everyone,

We're a German engineering firm specializing in district energy infrastructure, mainly district heating (Fernwärme), cold district energy networks (kalte Nahwärme), and geothermal systems. Up until now we've been doing our underground pipe planning in standard AutoCAD and Revit, but we're looking to move to Civil 3D to properly integrate the civil/earthworks side of things.

Our use case is specifically pressure pipe networks (pre-insulated KMR pipes for district heating, PE pipes for cold networks)

So: routing alignments along terrain, 3D trench modeling, cover depth checks, fittings (tees, elbows, valves), quantities for bill of materials, and proper plan/profile drawings.

A few questions for those with experience:

1. Is Civil 3D's pressure network tool actually the right fit for this? Or are there limitations that make it frustrating for this type of work (as opposed to water/gas utilities)?
2. Since the DACH Country Kit covers water and gas component lists out of the box, has anyone built custom component lists for district heating pipes (KMR / pre-insulated) and is willing to share their experience?
3. Any tutorials, YouTube channels, or courses specifically covering pressure networks in Civil 3D? Most of what I find is road design or stormwater. Utility/pipe network content seems harder to come by.

Hydraulic network calculation (pressure loss, flow rates) stays in dedicated tools. We're purely after Civil 3D for the geometry, earthworks, and documentation side.

Thanks in advance!

So, I've built quite a large corridor that covers all roads and a decent amount of lot grading for the first phase of a subdivision.

I'm now creating alignments and design profiles for cul-de-sac curb lines and adding corridor baseline/regions to grade the cul-de-sacs.

I've done 3 cul-de-sacs no problem. The latest one though... when the new baseline/region is applied it builds the corridor perfectly, but the corridor surface disappears in for the area governed by the cul-de-sac baseline and the main street region that this cul-de-sac connects to.

The corridor looks as it should, the rest of the surface remains unchanged, but this portion of the surface just disappears. If I turn off the cul-de-sac region (but leave it in the corridor), the surface regenerates in the main street region, but if I turn the cul-de-sac back on it disappears again.

Any ideas? Is my corridor just too big that it's going to act up? I considered doing all cul-de-sacs in a separate corridor and pasting the surfaces together, but it seemed this may make connection between the streets and cul-de-sacs potentially problematic.

Olá pessoal,

Trabalho na área de infraestrutura rodoviária e estou procurando recomendações de cursos intensivos de Civil 3D voltados para projetos de rodovias visando:

Modelagem de superfícies e corredores;

Alinhamentos horizontais e verticais;

Seções transversais;

Terraplenagem;

Geração de volumes e quantitativos;

Pode ser curso presencial ou EAD, desde que tenha boa didática e foco prático/profissional.

Se alguém já fez algum curso que realmente agregou na atuação com projetos rodoviários, agradeço muito as indicações e relatos de experiência
