Why isn't it possible to have the same hatch rotation in the viewport than in the modelspace?  For civil engineering we often need to rotate our viewport to have as little empty paper space as possible. We also work with annotative hatches because we use multiple scales in the same project. For now you can not have rotated annotative hatches in the viewport (I don't know why) because it is hard coded. Is it possible to maybe have a system variable where you van choose if the annotative hatch angle follows the modelspace or not? Maybe HATCHROTATIONRETAIN or smeting like that? Thanks in advance, Rik  Show More

I would like to be able to fix parts of a previously grading optimized surface and do a new optimization on only part of it.   I use grading optimization regularly, but it doesn´t provide the capability for accommodating changes. When a change comes, I dont want to reoptimize the whole surface, I want it to remain exactly as it was since other disciplines already account for given elevations, but when a connection somewhere changes, it would be nice to only reoptimize a given area or say only change as little as possible.   Now I create a new new base surface and a new boundary and optimize a small area for the change and paste it into the surface that came out of the previous optimization. Otherwise there might be changes all over the area.   I think there needs to be some way to be able to do iterations and say "I´m happy with this part, but let´s add more contraints to this area and only optimize that part from this point forward and keep the good parts" and then do it again and again until I´m happy with the whole area.

It would be interesting that the C3D user could create several profiles (profile user) for Superelevations of the same Alignment. Target: we could use a Superelevation table for each component :lane, shoulder,.... so if would be independent. Imagine this case:   Profile 1 (only available "Left Inside Lane"). Profile 2 (only available "Right Inside Lane), etc...   We could test different Superelevation Tables simply changing of profile in the settings.   Profile 1 would be always present, user cannot remove it. Profile 1 is available for old C3D versions.   API: Alignment.SuperelevationProfilesCollection(). Alignment.SuperlevationProfile(id).SuperelevationCurves();   stock subassemblies currently would be for Profile 1 but custom subassemblies we could create an input parameter "Select Superelevations Profile" enum.   Regards.

  The issue with Civil softwares is you type input values such as Superelevation Table (linked to an alignment not a Result corridor) or Wide table to shoulder, lane, etc.. but THEY ARE NOT the final values, the result corridor because you can use: -input parameters. -corridor Transitions. - Transitions in your SAC subassembly. -offset target or elevation targets -etc..   So Civil 3D should generate Diagrams and Final Tables (for reports) for Superelevations and Wide. I know that we can get reports (toolbox) from an specific code Link currently in C3D but we cannot get Diagrams or a simplified Table (Result table). This is a procedure that I have done to get diagrams for any type of code Link. https://forums.autodesk.com/t5/civil-3d-foro-en-espanol/truco-generar-diagrama-de-peraltes-sobreanchos-etc/td-p/14208188 The issue is this is done in my custom subassembly (in SAC) so is not available for other subassemblies. Basically, the procedure consist in creating a point whose elevation of that point is the slope value of a particular code Link. I have an string input parameter to request that code link. Due to I want 3 superelevation diagrams : lane, parking lane and sidewalk, I create 3 points. Then I extract those Corridor FL of those codes and project those FL to a Profile View (of the center alignment).   So please, Autodesk staff, create a tool to generate Diagrams (from code links), valid for Superelevations, wide,... without creating FL and then we have to project to Profile View.   Basically, from a Link we can get: Length, XLength,YLength, Slope,    so I think with "XLength and Slope" is enough to generate 2 diagrams.   Thanks in advance.                   Show More

Summary I would like to propose two related enhancements for Autodesk Civil 3D that would significantly improve workflows for surveyors, civil engineers, and professionals working with photogrammetry and LiDAR data. 1. Display Point Clouds in Section Views Allow Point Clouds (RCP/RCS) to be displayed directly within Section Views. This would enable users to: - Compare the TIN surface against the original point cloud. - Validate terrain models more efficiently. - Analyze roads, airports, railways, channels, and earthworks using real survey data. - Reduce the need to constantly switch between 3D views and Section Views. 2. Edit Surfaces Directly from Section Views Allow users to edit TIN surfaces directly from a Section View. Suggested workflow: - Select a surface vertex or triangulation in the Section View. - Move or adjust it graphically. - Civil 3D updates the TIN automatically or provides options such as: - Move vertex - Create Breakline - Create Feature Line - Smooth local triangulation All dependent objects (Profiles, Corridors, Volume Surfaces, and Section Views) would update automatically. Benefits - Faster surface correction. - Better quality control for drone photogrammetry and LiDAR projects. - Improved workflows for highway, railway, airport, and land development projects. - Easier validation of existing ground against surveyed data. - More intuitive editing, similar to modern BIM workflows. Why This Matters As point clouds become increasingly common in civil engineering, users need tools that allow direct interaction with survey data inside Section Views. These capabilities would modernize Civil 3D and greatly improve productivity for surveying and infrastructure professionals. Thank you for considering this feature request. Show More

Hello everyone, We use the IFC4x3 plugin in Civil3D 2026 to create coordination models. It’s easy to set the base point and the base point elevation. However, we’re facing a problem: in many of our projects, the base point is defined by architects, and it’s rotated relative to true north. However, during IFC 4x3 export, the output is always oriented north, regardless of the base point and the reference coordinate system. It’s not possible to rotate the model before export because our surfaces and corridors must be georeferenced. As a result, we can never deliver our model as required; instead, the BIM manager has to rotate our model. I would like to see a feature here that allows us to specify a rotation.

Problem In Structure Labels, the Connected Pipe Direction component displays hard-coded cardinal direction abbreviations (N, NE, E, SE, S, SW, W, NW). These values are automatically localized based on the language of the Civil 3D installation, but they cannot be customized or accessed through Expressions. This creates several limitations: Companies working in multilingual environments cannot use a single Civil 3D installation while complying with local drafting standards. Users cannot adapt the abbreviations to company or agency standards. Expressions cannot be used to translate or replace the returned values. For example, French drafting standards use O, NO, and SO instead of W, NW, and SW. These abbreviations are only available when using the French version of Civil 3D, making it impossible for users of the English version to produce compliant labels. Proposed Solution Instead of returning hard-coded text, expose the connected pipe direction as a configurable value. Any of the following solutions would address the issue: Allow users to customize the text displayed for each direction (N, NE, E, SE, S, SW, W, NW). Expose the direction as an enum or numeric value that can be used in Expressions. Provide a mapping table within the label style or drawing settings. Benefits Better localization without requiring a language-specific installation. Support for company, agency, and regional drafting standards. Greater flexibility for label customization. Consistent with other areas of Civil 3D where abbreviations and displayed text can already be customized. This would be a relatively small enhancement with significant benefits for international users and organizations maintaining standardized drafting practices. Show More

A valuable enhancement to Civil 3D's QTO workflow would be the ability to assign pay items directly to drawing layers, similar to how pay items can currently be associated with network parts through the Parts List.   With this capability, any object drawn on a layer could automatically be recognized by the QTO Manager and included in quantity calculations in real time.   Key benefits: Automated quantity take-offs with less manual mapping and configuration. Real-time quantity updates as design elements are created or modified. Improved estimating accuracy and consistency across projects. Reduced risk of human error from manual pay item assignment. Greater value and adoption of existing QTO functionality. For organizations that use standardized drafting practices and advanced estimating workflows, linking layers directly to pay items would streamline the design-to-estimate process and allow quantities to be generated automatically as designs evolve. This builds on an existing Civil 3D concept and could provide significant productivity gains with what appears to be a relatively straightforward implementation. Show More

Autodesk Civil 3D already provides the ability to define section styles and apply different hatch patterns based on cut and fill materials. However, when generating construction documents, the current workflow requires users to manually create and manage legends in the sheet layout to explain the materials represented in the section views. I would like to suggest an improvement for future versions, such as Civil 3D 2028: the ability to automatically generate a dynamic material legend linked to the section views. The proposed functionality could: Read the materials and hatch patterns already defined in the section styles; Automatically create a legend in the layout showing the corresponding materials and hatch representations; Keep the legend synchronized when section styles, materials, or design information are updated; Allow users to select which materials should be included in the legend. Currently, even though Civil 3D can display different hatch patterns for excavation and fill materials within the sections, the documentation process still requires manual legend creation. For large projects with many section views, this becomes repetitive and increases the possibility of inconsistencies between the drawings and the design data. Adding a dynamic material legend connected to section views would improve productivity, maintain BIM data consistency, and make Civil 3D documentation workflows more efficient for civil engineering projects. Thank you for considering this enhancement for future releases. Show More

If I want to create a point in the subassembly to a specific elevation I must have a TARGET elevation and I have to assign an entity (pol3d,FL,...) as an elevation target. I cannot type an input parameter "elevation" in the subassembly composer to assign that elevation to a point. Maybe SAC needs another type of point where we were able to assign an elevation.   If I want a point with Z= 0 I could do   From point :P1 Delta Y= -P1.Elevation   (BUT SAC NOT ALLOWS NEGATIVE DELTA Y)   Thanks.

In Project Explorer if we select a Layout Profile we can export it to 3D DWG, as a 3d polyline. The issue is this feature is working wrong because if you have a layout profile which starts in the 20 station, 3D polyline generates a vertex in station 0 with elevation 0. It would create vertex of the 3D polyline only if is part of the profile.  Currently that command generates a 3D polyline of the alignment and then inserts PVI with new vertex on that 3D polyline. That criteria is wrong...   As a surveyor we load files in survey controller in 3D polylines but only of PVI profiles. In fact, if the layout profile has parabolas, this command needs settings to set the frequency in parabola to create new vertex in the 3d polyline.   If the user wants all the alignment (even with some vertex with 0 elevation) and PVI inserted on it, maybe you could add a new option to the usar from a dialog box of parameters.   Show More

In Civil 3D if you open Options, go to the User Preferences tab and select Default Scale List. You only get a choice of Matric or Imperial. The Imperial choice only contains Architectural scales. So it's impossible to set Engineering Scales as the default. There are ways around that. But I think you should ask the AutoCAD Team to add Engineering as a choice. So you could choose Metric, Architectural or Engineeing scales as the default list.   Show More

Hi. Some commands of C3D needs collaboration of the user by picking graphically to select vertex or points. This is good but I would like also to do it by table data. This would be the case of SetFeatureGrade. It we have the FL Elevations Editor open, we could select several rows (vertex and Elevation Points) and then right click of the mouse and select "SetFeatureGrade" in the context menu.   I would like to do operations (interpolation, lock elevations, lock grades, ....) inside the FL Elevations Editor.   Thanks in advance.     Show More

Dear sir and madam,   I'm a Civil Engineer in Germany. I have designed several industrial area in Germany. The products from manufacture REHAU are frequently used in German projects, and their manholes (AWASCHACHT PP) are already existing in DACH pipe catalog.   It would be great, if their pipes could be also implemented in Civil 3D by Autodesk in the future.   I got the pipe catalog from them yesterday. You can contact their BIM Specialist Sefanja Verkaik ([email protected]).   Thanks a lot!   Best, Siyuan Liu Show More

When it comes to sheet production, the tools in c3d are great. If. You are locked into an area before cutting the sheets. As with anything in C3D, change is inevitable. So we need a way to link the produced sheet views to reflect any revisions to the position and/or rotation of the view frames, whether this all happens in the same or separate files. Show More
