Dear citizens and colleagues of Civil 3D :D
I always thought that when I exported a DWG from Civil 3D to AutoCAD format, the COGO points markers were exported as a point entity and not as a reference block. When I talk about markers I'm talking about basic markers with a cross or an X. Is there any way to create these AutoCAD Points when exporting?
I'm running Civil3D 2020, and I have an old file with objects called "AEC_Contours". I can't do anything with them. I assume they have some sort of surface information, but I can't access it.
Is there to "explode" the contours, convert them to plines, or some way that I can being to manipulate them?
Has anybody dealt with this before? I've never needed to exclude elevations before so I've never used it. Thanks.
I’ve ran into this issue before and fixed it before and I can’t remember what I did and it’s driving me crazy. If I make a feature line, select all my settings including generate surface automatically including volume information, etc. every it fine. When I realize for example my feature line needs a lot of work like maybe I find out okay I need to start over because I need to move it and redo the boundaries for whatever reason. So I delete it and the surface. Update my poly line. Generate FL from object once again, update the feature line as needed, then go back to my grading generation tools, assign it to the same grading group etc. should be the same settings. It generates grading but no surface. It’s like somewhere when I deleted the surface a box got unchecked somewhere and I can’t find where that is.
EDIT: I figured it out. Prospector, under sites, your site, grading groups, right click for properties and then click the selection box.
Why when you delete the surface does it unselect this option and why is it so buried 😂
I was trying to make the alignment table and so I added tags for the alignment. "multiple segments" however when I clicked on the alignment, seemingly nothing happened. So when I go to create the table, I get a massive list of lines and curves information. So, I delete those and re-add the tag and remake the table, However, I'm now up to L55 as you can see in the picture. Is it possible to reset the numbering for that back to 1? I hope I am making sense. I am still learning civil 3D and this is an assignment I'm currently working on. I will ask the professor as well but I was hoping that I could fix it before I go into class on Friday.
I’m trying to figure out if this is an online self directed course or is there like an online class I’ll be joining? How hard is it ? And how long does it take to complete? Thanks
I'm new to using subassembly composer and not too familiar with corridor models. I've created a subassembly in the composer then an assembly in civil 3d, but when I make a corridor from it, i don't see any connecting lines (whatever they are called) I just see the profile of my subassembly at the prescribed interval. Any idea what step I might have skipped?
Edit, thank you all. It’s definitely a point code issue.
any one knows here i can buy pressure catalogue that have all standard pipes and fittings with high LOD ?
In my profile view I have this random magenta line tied to my storm sewer structures. Not sure what it is or how to get rid of it.
I have received data from a client in excel format of data to determine 100 YR flood elevations. I am trying to project this data into plan view to show those boundaries.
I currently have an existing surface, and his sample lines. A corridor will not work in this situation, so I have copied his sample lines, and set them to be feature lines with associated elevations from the data provided to me. This would be simple for 53 sections if he gave me the left and right offsets for the intended elevations, but I only have the overall width at each section.
Creating a comparison surface is something that says will work, but without having a defined offset for right and left, I just don't feel comfortable or able to get this to work. I have 22 years of experience with cad and have never had a client so hard headed with providing information like this one.
So with that information, how do you suggest I roll?
I was tasked to add a ditch to a surface with a slope of 3:1 and 7’ width top and 1’ width bottom. The ditch was only drawn using polyline. I used to model ditch using corridors, but in this task, I was asked to do if with feature lines alone.
How can I do it?
Thanks!
I have a surface referenced into my drawing, and I want to swap it with another referenced surface. I have a lot of feature lines that are relative to the first one. Do I manually have to retarget them all to the second one?
Is there a way to create ROW parcels with varying width? We often have lots that dedicate some of the frontage to the ROW.
Just curious, do any of you use both spline and straight leaders for your projects? How so?
Leaving as vague as possible.
As stated in the title, I spent over a month designing and redesigning a site to meet the clients ever changing vision for this public-use infrastructure. Having to stay super late for the third night in a row and redesigning our entire set of plan sheets to match what he actually built so he can be "reamed" by the city tomorrow (his words).
At what point do I contact governmental appropriate offices to address the situations regarding noncompliance on ADA required areas, and complete deviations from state applications? The occupancy HAS to be lower than permitted at this point, as he runs the equipment at 3/4 due to not needing the 'full' power of said equipment. This is one of those grey haired 'ive done this for decades' types of guys who will blantantly disrespect you to your face if you dont have a full head of greying hair. Hell, the dude even tried to blame the actions of his own workers on us. Couldnt even remember his own design layouts and couldnt read what a fence detail wast actually a grate cover detail. Mfkr hasnt even paid us anything yet. Probably wont for a few years thanks to our shitty outgoing invoice situation, but thats a whole other can of worms.
Its just serious irked me the wrong way But im between a rock and a hard place due to this facility being the only one of its kind in our area of the state. I dont wish to have them perma shutdown and have the community loose out on being able to enjoy it.
Or do I just need to stop being a b..ch about this?
I need a beer.
Hello Everyone,
I am having this issue with my surfaces where everytime I make edits to some other part of the surface, autocad will insert these points with squares around them. They are highly annoying because the elevation autocad inserts is never correct and leads to really weird breaks in my surface. Is there any way of stopping this from happening?
I'm using civil3d 2025 and every time I create a feature line and use that to create offsets, the new lines dlwill not save in dxf format. They just dissappear after I close and reopen the drawing. They seem to stay fine if I save in dwg format but I need dxf to upload to my trimble instrument
SOLVED: FOR ANYONE HAVING THE SAME PROBLEM, EXPORT THE DRAWING AS DXF RATHER THAN SAVE. ALL FEATURE LINES REMAIN!
Hi all, i did some searching on this and couldn't find a great answer.
I have a feature lines that are defined with elevations, and our survey team is now ready to start layout. I need to convert the feature lines to a polyline, likely 3D. I have been using the explode command to do so but the geometry of the arcs and curves are lost in the process. Can this be avoided without loosing the elevation data? I've seen people change the elevations of the feature line to the same elevation and upon exploding Fline the geometry is held, that is not an ideal work around as keeping the data is preferable.
Surface created by the teacher
Hello, I am a new Civil 3D user, I am taking an premade online course for Civil 3D. The teacher imported predetermined points and made a surface from it. He attached the points data and so i used the same data to create the same points and surface. I have done everything the same way, and the surface properties of his work and mine are completely same, but both look completely different. Mine has little to no contour lines visible while his has rich and dense contour lines. The contour intervals of both the drawings are same at 1m minor and 5m major intervals. What am I doing wrong here?
I have tried LEVELOFDETAILOFF command, didnt work.
I have tried checking if all the layers of the surface are on, everything is fine there.
I have checked if the minor and major contours are on in the display settings of the "edit surface style" menu, both are on along with along with borders, just as the teacher said.
(Im sorry if i messed up any terminology, I am still learning)
EDIT 1: Here are two more screenhots to show the difference in the level of detail.
Above is a zoomed in section of my drawing
This is a zoomed in view of the teacher's drawing.
The most recent version of Civil3D I was using is 2023. Got a new computer with specs suitable for any version so I was wondering if the upgrade to 2024 is worth it yet or should I stick to 2023 or even go to an older version.
Thanks
Is there a way to quickly break a specific polyline at matchlines?
Our customer wants quantities for each sheet. We usually do this by having a polyline for bore footage that is broken at the match lines. The BREAKATPOINT command is a decent way of doing this, but it's slow when you have miles of plan projection at 100 scale.
I couldn't find a way to break the line at the intersection of all match lines at once. Is there a way for Dynamo to do this?
Currently still learning Civil 3D and design of roads , after adding a surface to my road corridor and limiting the boundary to extents of the corridor my surface still spans over my area designated for housing and other roads.
Alot of drawings I´ve seen have two different scales set in the same PDF, one for A3 paper size and one for A1. Is there any specific way to set two different scale in the same plot so the reciever can print both A3 & A1 and still know what scale they would use?
Hello, I need help creating an exit ramp on Civil3D. I am super new and honestly don’t know what I’m doing.
I currently have a surface in the file and I have a the edge of pavement line that I created into an alignment so it has stations.
I am wanting to connect a NEW road to the existing alignment (edge of pavement) and have it enter a parking lot. But I’ve tried everything and I feel like it’s wrong. Can I do this with a feature line or do I create a new alignment?
Can anyone help me out?
Is there a way to disable the "Multiple" Ribbon?
Everytime there are more than one object selected, the ribbon change to multiple...and is nearly empty...only 4 options I barely use.
I want C3D to stay with the "Home" Ribbon (when there is a different object type)
For example i often rotate "closed Polylines with a hatch". I select both and than i have to change back to home ribbon to find the rotate button...
...any suggestions
I have a problem projecting 3D solids to profile view. I have a alignment where is sheet pile retaining wall (middle line of the wall is same as alignment). When trying to project those 3D solids (sheetpiles) to profile view, it does project 98% of them, but few are missing. When trying to project those where error occures, there is said in the command line: "There are objects outside of the Profile view's station range and will therefore be ignored." For what I understand, what is station range of an aligment, they aren't outside of the station range, but still error is there. Any suggestions? Thanks!
I posted yesterday about volumes of a hill and moving masses from Project A to Project B.
And I´ve made the hills using a feature line of the top topography and graded it down to excisting ground level. Then I infilled the area of the grading, my problem now is that if I adjust the volume with the grading tools my infill disappears and that obv changes the total volume outcome. If I try to infill it again nothing happens and I cant seem to using the grading toolset to infill the area, has anyone encountered this problem where your infill disappears? And how did you solve it?
Hi All, is it true that Civil 3d no longer has Macros?
I used to use them in my old job many moons ago. I've been toying with some ideas in my head the last few weeks on improving some of our survey deliverables, and I was planning on leaning heavily on macros.
After some googling it seems like they're gone now?
Am I way off base here and just not finding them? And if so, is the only other solution VBA / .net / AutoLisp?
