DREF Assembly

Status: Gathering Support
by Explorer magnus.svensson on ‎03-22-2017 01:03 AM

It´s often a good practice to divide you corridor design into parts of the alignment, it´s faster to work and in revision faces you can pinpoint the part your interested in without worrying about messing up the rest.

The first need is to create alignment and profile in separated files from the corridor, that's covered.

Next step is that you want the same assemblies in alot of corridor files, this is a manual copy process that is time consuming.


I would like the possibility to DREF assemblies.

With that you could build a master assembly file for your project and dref the assemblies out to the corridor files.

Circle as an alignment Entity. (ideal for roundabouts)

Status: Gathering Support
by Mentor on ‎03-21-2017 05:56 AM - last edited on ‎03-21-2017 06:01 AM |

There are a lot of civil softwares which have a particular type of alignment entity called "circle", especially for Roundabouts.


Here, even in the "Create Roundabout" of Vehicle Tracking, it needs 2 arcs to define a circle as the alignment of the roundabout.



Please, add another Alignment Entity called "circle" within the Fixed arc category in the "Geometry Editor Tool".


And use directly this type of entity in the Autodesk Vehicle Tracking.


Moreover, we can´t create an alignment from object (an ACAD Circle object).



There are exactly zero reasons to design this scroll bar to be 4 pixels wide. It takes time to steady the mouse on this tiny area to scroll.


Make this at least 10px wide like most other scroll bars in the world. Please.



Smart labelling in the Alignment Station Labels.

When we create a roundabout, this scenario is typical.

There are 2 labels overlapped in the start aligmnent and end alignment to display the start station and the end station.




It would be interesting a way to set this in the Alignment Station Labels.


Align Dragged State Labels

Select multiple labels in dragged state, select one label for all selected to align to.  Similar to the "align labels" command for multi leaders.



It would be nice to create a point group from a point's attributes. Some of my customers use tons of "descriptors" for pipelines. These "attributes", or User-Defined Property Classifications, hold lots of information. For example, lets say that one of these classifications have a material. It would be nice to create a point group based off of that material.

I really wish that Civil 3D supported basic modify Commands, like being able to TRIM a Feature Line using a Polyline, etc in an XREF.


It is really frustrating to have to first draw a line, NCOPY, etc. before performing such a fundamental, repeated task.




This suggestion is about Feature line creation. 

When you are designing a feature line, and you make a mistake at a vertice, you must imput Elevation (Or Grade, Slope, Difference, Surface, etc), as image bellow:

Imputing elevation.png


The suggestion is include an option UNDO at this point, so we will be able to undoes the vertice position before insert Z data.


Thanks Autodesk, to listen us.

Projection of Building Sites to Profile Views and Cross Section Views

Status: Gathering Support
by Explorer joaolgmartins on ‎03-20-2017 12:36 PM - last edited on ‎03-20-2017 12:38 PM |

I'm trying the interaction between Civil3D and Revit, importing Revit models to Civil3D through ADSK (Autodesk Exchange Files).
The importantion goes without problem as a Building Site and would be interesting to use building sites projecting them to Profile Views and Cross Section Views.


Need another Watershed type in the Watershed Analysis that finds and delineates the top spill containment elevation for a depressed area.


This is the elevation where the ponding water would start to spill out from the depression.

Vertical Profile Band Improvements

Status: Gathering Support
by Collaborator kcobabe on ‎03-14-2017 05:39 AM

This suggestion is actually a bit baffling to me and there may already be a way to do this, but I have not found it yet.  Also it covers a couple very simple things that should have been added to the simple vertical geometry band style.


  1. Profile band for a station range.  Why this has never been added is beyond me.  At one time I thought I saw it in there but I must have been in dreamland because in 2017 there is no station range for profile bands.  This could be handy when you need a label to disappear when it does not exist.
  2. A "For Each" label system would be invaluable for most people who do utilities.  Right now we have to go through and make things not visible and use multiple bands to accomplish this.  In reality we should only really need one band to do all vertical geometry.
  3. Expressions!!!  Why is there not a way to add expressions?

For Fitting and Appurtenance Styles, the 'Profile' Tab is missing in the Dialog Box. This prevents the use of 'Display as user-defined block' in a Profile View. This Tab and Function needs to be added in order to use custom blocks for Fittings and Appurtenances to meet Drafting Standards.

If my set of drawing has 10 Civil 3D files and 5 ArcMap files, the 5 ArcMap files are not in my sheet set.


It would be nice if you could choose to add a sheet as an external sheet.


By having an external external sheet option, it simply turns that sheet into a shortcut to that external file. This way you could add any other files to you sheet set. Surfer, ESRI ArcMap, Global Mapper, etc.


Give me some basic sheet set options like naming the sheet, but ultimately, If I click on the sheet, it will open a link to the external file which would open it in its default application for that file type for editing.

QSelect works perfectly using some properties of COGO points, but not using styles.

In some cases when points got their styles not from point group but from description keys we can't build a set using labels.


Add point style and point label style to the list of properties which QSelect can use. I'm sure it would be a very useful feature.

Point import format manager hasn't really changed a lot in the last 30 years... It would be awesome if point import would check a file for commas and quit asking if they are there or not... It should be an easy check.  Also, add the option to skip the first X number of lines of the file... Everyone that has a clue has a header on their point file, that they have to delete in order to use.  Which then orphans the file, it no longer has the header info to tell the fields apart...


Also, could it give an error message if a line can't be processed, instead of just dying?  A blank line at the end of the file shouldn't crash your import!

Assembly labels

Assemblies should be labeled natively in C3D.

Yes, you can add text object with field to display the linked assembly name, with an extra lisp or without, but this should not be achieved with the extra step. We need to display the assembly names every single time to browse the assemblies.

Automatic intersection object

Status: Gathering Support
by Participant EricGates on ‎03-07-2017 09:33 AM

Be able to toggle so that intersection objects can be automatically or globally placed where ever alignments intersect.

Also put the intersection object as its own tool instead of having to access it through the intersection wizard by unchecking the other functions.

Since the intersection object already maintains the intersection location and it has the ability to assign vertical hierarchy of any of the alignments profiles between each alignment it can be leveraged for much greater geometry definition and control beyond just a dynamic curb return alignment.

Surfaces - Update Performance

Status: Gathering Support
by Advisor fcernst on ‎03-08-2017 01:00 PM

The surface engine for Civil 3D greatly needs an update to be able to handle our surface analysis requirements.  The Civil 3D surface and surface analysis engines are not utilizing the available computer resources. Far from it.


See this thread:


1. Needs to remember 5 most recent projects in the File: Open menu.

2. Needs to use the same File: Open dialog box as C3D, with place to store favorites.

Its about time we had a fully working roundabout wizard that creates a corridor. It needs to be one that we can...


  • Change corner radius
  • Change approach road widths
  • Change approach road gradients

How can we have a fully properly working junction wizard but not a roundabout wizard?


and the poor excuse of a wizard that we have now is a joke, it cannot properly edit a roundabout the way junctions can be editied
