Dear Civilists, currently there is only one standard method available, Banker's rounding. Noticed during labelling COGO-Points. This means: “Banker’s rounding is a midpoint rounding scheme (round-to-even).  When a value is exactly between two candidates, it is rounded to the one with an even least-significant digit. Example: 73.5 → 74, 74.5 → 74, 75.5 → 76"   This method is completely different to what is taught in engineering schools. Therefore this standard rounding isn't suitable to engineering tasks, for what Civil 3D is made for, I guess.   It is urgently needed to add a "engineering rounding" or "commercial rounding" or "rounding to the nearest". Means if the last deleted digit is 5 or more, than the last remaining digit will be rounded up. If the last deleted one is 4 or less, than the last remaining digit will stay as it is. Example: 73.5 -> 74, 74.5 -> 75, 75.5 -> 76, 73.4 -> 73 Please support this idea, so that it will come true.   All the best. Show More

It would be very valuable to have a tool that allows subassemblies to be applied directly to surfaces, rather than being restricted to corridor-based workflows. Similar concepts exist in other civil modelling platforms, demonstrating that this approach is both achievable and beneficial.   In many scenarios, particularly involving non-linear earthworks, corridors are not an appropriate modelling approach. In these situations, designs are typically delivered using feature lines and surfaces, which means the powerful parametric behaviour, material definitions, and quantity take off capabilities of subassemblies cannot be utilised.   As an example, in my role designing road access, drainage, and earthworks for substations, platform construction typically consists of multiple material layers (e.g. Type 3 fill and granite chippings). Currently, this is modelled manually by creating a finished surface and then generating an additional offset surface to represent the formation level. While workable, this approach leads to manual calculations for the materials of the platform and no representation of the layers of the platform in 3D.   Conceptually, this functionality could work by taking the points of the surface and applying the layers defined in a subassembly across the surface, generating continuous 3D solids and the ability to create corridors surfaces in a similar manner to how corridor shapes and surfaces are produced.   This would streamline workflows, improve model accuracy and support more reliable bills of quantities. Coordination would also be improved, as layered assemblies would appear consistently with corridor generated objects within coordination and federated models. Beyond substations, this functionality would be highly beneficial for other non-linear external works, such as footways, hardstanding areas, landscaped areas, SuDS elements, and interfaces around buildings where corridor modelling is not appropriate.

Hi everyone,   There doesn't appear to be a section for Content Catalog, so I'm posting it here. Current issues with Content Catalog (CC) for AutoCAD / Civil 3D There is a lack of graphical interface within AutoCAD / Civil 3D – nothing exists on the ribbon, even after installing the Content Catalog Extension. This is acknowledged via a knowledge-base article, but no indication as to if or when a CAD-based interface will be available The only way to access it within CAD is via the command CONTENTCATALOG (although this appears to not have anything to do with it). The graphical interface looks like something out of the 80s When trying to tie-in with live website databases, it’ll add it and show it as a "content catalog" like the above image shows, but won’t actually work. When trying to access a website-added content catalog, you end up with an endless loading window that doesn’t do anything It would appear to be extremely slow, to the point where it doesn’t work. A variety of different live URL links have been tested, none of which work. Further development needs to be done to ensure this is tied-in with Live Databases instead of links to different files on a computer system (such as an .html file). I'm now convinced that the application appears to almost work completely separately to the website-version of CC and has nothing associated with it. When accessing via the website, there is no method by which you can change the layout / arrangement of the files within collections, you have to manually navigate the massive icons There needs to be a better way of managing the display of items as well as the organization of them. Bonus points if there is a way to tie-in with an API for direct access / connection to Company-based CAD customizations and/or to build a CAD-side interface. And of course, being an AutoCAD / Civil 3D user we are still waiting for thumbnail previews to work without the need to manually upload images! Problem Statement We have a problem where we need to have a centralized database that contains all of our data (such as Blocks) that we need to access across multiple countries. Example problem: CAD Drafter in Australia needs to access our New Zealand Blocks, but they’re located on our NZ Server, something that they do not have access to. Therefore a solution is required for them to be able to seamlessly access this data. Rinse and repeat this scenario for ~hundreds of users. Potential Solution(s) Create a singular cloud-based database that all users can access. This, for example could be in the form of: A properly working Content Catalog for ACAD / C3D users (such as what Revit users have experienced and loved over the years from Unifi). Personally, I recommend that your Civil 3D / AutoCAD developers directly interface with your Revit developers to see how well the Content Catalog integrates for them and how it is used. An ACC (Forma) hosted project, specifically for the storage of items such as Blocks, for all users to access. Another solution? What alternatives are out there? Has anyone come up with a clever solution to this classic problem? In either case, there would also need to be an intelligent / mostly automated feature by which Users would be automatically added to these platform(s), so there is no manual arduous interventions required in order to provide basic access for employees – which would number in the hundreds, potentially thousands in some very rare cases.   This is an open discussion and while I hope for some serious Content Catalog development specifically aimed at AutoCAD / Civil 3D users, I look forward to some debate! Thank you. Show More

Hello, sometimes my codes for links and points are quite long and overlap. It would be great if I could just see point codes and hide shape and link codes, see link codes and hide shape and point codes. Show More

Hello, sometimes I need to select multiple geometry elements in a flowchart. Now I use Ctrl to select multiple elements, but it would be great if I could select them using window boxes or freehand lassoing  - like the selection is done in Civil 3D Show More

Currently there is no ability to snap to the center or insertion point of a pressure fitting or appurtenance in a profile view. Please add that ability. There is already a grip for it when selecting the object, but there isn't a way to snap to that same point. Show More

Still need the simple function, that when you select multiple lines that in the Properties window would show the total or cumulative length. Really helpful for takeoffs, because honestly the takeoff function in AutoCAD is very complicated and waste of time to put together unless it’s a massive project. So for 90% of projects, building the CAD file for takeoffs using AutoCAD’s automatic takeoff is a shear waste of time and resources. Show More

It would be incredibly helpful to have the option to change the default values set by pipe networks rather than utilizing project explorer/the panorama to make mass edits after creation. For example, the 'Pipe Flow Direction Method' defaults to "Start to End", a system toggle under the Edit Feature Settings to set this to the "By Slope" option feels pretty intuitive Show More

In Civil 3D, almost all dialog boxes are resizable. Only a few apparently aren't.   Why shouldn't I be able to do that everywhere in this day and age? It makes no sense. Please implement the feature that allows all dialog boxes to be resized so that more information can be seen. I noticed this with the profile style style and the link styles for code style sets.   Thank you for considering and implementing this.   Regards, Philipp Show More

I'dlike to propose a new feature for Autodesk Civil 3D: Alignment Regions, accessible through the Alignment Properties dialog box. This feature would allow users to apply station range-based style overrides to an alignment, similar in concept to how masking can be managed by range. The idea is that an alignment would retain a base style such as Proposed, while users could define specific station ranges where that base style is overridden by another selected style. Proposed Functionality Using a table-based editor within Alignment Properties, users could define station ranges and assign alternate styles to each range. For example:   Station Range Style Applied 1+000 to 1+500 Stage 1 Style 1+500 to 2+000 Stage 2 Style   In this example, the alignment would use the base style overall, but display different styles across defined station regions. This would be especially useful for: staged construction phased works temporary versus permanent conditions design option presentation clearer visual communication in complex projects Additional Suggested Options To make the feature more robust, it would be helpful to include: Lock to Start option Lock to End option These controls would help maintain the intended style extents if the alignment geometry changes and the start or end stations are updated.   Associated Labeling Enhancement A further improvement would be for horizontal alignment labels to automatically recognize the boundaries between style regions and place a distinct label at each transition point. For example, if one style region ends and another begins at station 1+500, Civil 3D could automatically place a label at that interface. This would provide a clear visual marker for designers, reviewers, and construction documentation.  If the Alignment Region changes, then the label shifts accordingly.   Why This Would Be Valuable This enhancement would significantly improve: alignment style flexibility workflow efficiency clarity of staged or phased design presentation consistency in documentation and review Overall, Alignment Regions would be a practical and powerful addition to Civil 3D, helping users manage complex alignments more effectively without needing workarounds or duplicate objects.   I believe this feature would add real value to many Civil 3D workflows, and I encourage Autodesk to consider it for a future release.

Enable the ability to project IFC onto Section Views in Civil 3D As requested by an user, it would useful to incorporate an option to project objects from IFC files coming from Revit, for example, to Section Views.   Direct feedback: "In Nordics, we receive more and more IFC files that we want to be able to handle in our Civil drawings. It could be that we, in our cross sections, would like to visualize the environment and not only the corridor. It also helps the design validation, meaning if we should "connect" the corridor or surface to the IFC we would like to see that that is the case in the cross sections. Like if the IFC is a building and we are creating the surface and superstructure that lies against the building. Or as in this case we have a corridor against a sheet pile or that type of object. But could also be for clash detection purpose." Show More

Please add conflict resolution options when pasting one Civil 3D surface into another.   At present, when Surface 2 is pasted into Surface 1, the pasted surface simply takes precedence wherever the two overlap. There is no option to control how overlapping elevations are resolved, which can limit usability and create avoidable workarounds/rework.   Proposed Improvement   When a surface is pasted into another surface, Civil 3D should prompt the user to choose one of the following options:   Option: Behaviour: None Maintains current behaviour Keep Highest Uses the higher elevation where the two surfaces overlap Keep Lowest Uses the lower elevation where the two surfaces overlap   The default should be None, so existing workflows remain unchanged unless the user chooses otherwise.   Why This Would Help This would be extremely useful in workflows involving: existing ground and design surface comparisons temporary and permanent surfaces construction staging earthworks modelling merging multiple source surfaces resolving overlapping terrain conditions without manual editing In many practical cases, users do not simply want the pasted surface to override everything. They want the resulting composite surface to reflect either the highest or lowest elevations in overlapping areas, depending on the design intent.   Additional Improvement: Automatic Intersection Breakline To make this behaviour reliable, Civil 3D should also: detect the intersection between the two surfaces create a breakline along that boundary This would help prevent unexpected triangulation across the overlap zone and produce a cleaner, more predictable result.   Benefit This enhancement would: reduce manual surface editing improve control over pasted surface behaviour make composite surface creation more intelligent reduce triangulation errors near overlap boundaries better support real-world design and modelling workflows This would be a very practical improvement for anyone working with complex surface models in Civil 3D, and I believe it would add significant value to future releases.

Based on users’ comments, kindly requesting Autodesk to consider a future enhancement in Civil 3D that enables reliable and fully supported use of centralized catalogs (e.g., parts catalogs, subassemblies, pressure networks, etc.) hosted in Autodesk Construction Cloud (ACC) or on shared servers. Civil 3D currently cannot reliably use catalogs stored in Autodesk Construction Cloud (ACC) or on shared servers, forcing users in multi-user projects to manually maintain local copies on their machines, which creates a high risk of data inconsistencies, model errors, lost information, and rework when catalogs are missing, outdated, or incorrectly copied—an issue that significantly impacts collaboration and contrasts with other Autodesk tools like Revit that support centralized libraries effectively.

I would like to report that it is currently not possible to populate the IfcProject LongName attribute during IFC 4x3 export using the "File-name_Project_IFC_Properties.csv" file. I kindly request that this functionality be implemented or improved. For example, the IfcProject ObjectType attribute can already be populated using the same CSV file, and extending this capability to the LongName attribute would ensure greater consistency and flexibility in the export process. Thank you in advance for your attention to this matter.   Mauro Show More

Come on Autodesk, let's have the ability to add crossing pipe labels in plan views with their top and bottom inverts and separation distances. There was a free tool on the app store called Husson Tool - Crossing Pipe Label, but they stopped supporting it in 2024 I know this is capable if they did it back in 2019. Show More

  Civil 3D currently requires the Reference Templates UI (Manage → Styles → Reference Templates) to detach/remove a reference template from a drawing. There does not appear to be a documented API or command-line method to perform this action programmatically. This makes it difficult to automate workflows when processing large numbers of drawings.   Many organizations use reference templates to enforce standards during production, but later need to remove the template reference when: delivering drawings to consultants or clients archiving project drawings converting standards-controlled drawings to standalone deliverables running batch cleanup or migration workflows Without an API or command-line command, this step cannot be included in AutoLISP, .NET, or batch automation tools.   Proposal:   Expose reference template management through either: API access list attached reference templates detach/remove them programmatically or Command-line support Example concept:   -REFERENCETEMPLATES LIST DETACH ATTACH     This would make the feature scriptable and allow integration into automated CAD management workflows.

The QSELECT command has object Styles as one of the properties that can be used to filter selection results.  However this feature does not seem to work.  Any value entered into a search that queries Styles always returns 0 results. Please can this be fixed!  There are many incidents where I need to select all labels / objects of a certain style but unable to do with using QSELECT, instead I have to select all of these objects manually and this can be very frustrating and time consuming.       Show More

It'd be very useful to hover over a Featureline and get in the tooltip a list of surfaces and corridors that this feature line is included in their definition.   In a drawing with multiple Corridors, gradings and lots Featurelines tend to be abundant and after several design changes some of them become obsolete, or needs modifications. The problem is it's often difficult to keep track of what a certain Featureline is for, and whether deleting it will cause unwanted changes to one of the surfaces or corridors in the drawing or not.  Including this info in the tooltip will be great IMO.

Based on user's request, kindly asking to improve assembly sharing capabilities in Civil 3D by enabling a centralized and reference-based workflow for assemblies across multiple drawings. Currently, assemblies cannot be shared via Data Shortcuts, which limits collaboration and consistency in corridor projects. Users would benefit from the ability to maintain a single source of truth for assemblies that can be referenced, updated, and synchronized across DWG files without relying on manual redistribution through Tool Palettes or templates. Enhancing assembly shareability would improve efficiency, reduce duplication, and support better version control in multi-user environments. Show More
