Flattened curved elevations / sections

Flattened curved elevations / sections

When elevated, curved surfaces do not show the full length of the wall.  Moreover, graphics become skewed.  We would like to be able to wrap an elevation tight to the curvature of the wall so that the elevation appears to be a flattened out curve.  You could do this by offsetting a line from the curved wall and picking that line as the elevation path.

In Revit, while creating a section, the section is linear in shape. However, in Revit 2020, the elliptical wall is being enabled newly.

It would be much helpful if users can have curved sections as well.

Seems possible, but the section would not have a "beyond" extents.

Do u know how to use curve section in Revit?

Definitly needed for infrastructure. This is possible is Allplan, in Civil3D, why not in Revit...

We create excavation shoring plans.  Shoring elevation views typically "develop" walls, that is, show the actual wall lengths on the drawings instead of the orthographically-projected views.  Civil-engineering software has done this forever for things such as road alignments.  It seems that Revit should have had this functionality years ago.

On numerous projects we are working on at the moment we are being asked to produce developed elevations along the length of retaining walls and secant walls where the walls either kink off a different angles slightly or are curved. While in some cases we can use Revit sections to stack views to create the impression of a developed elevations, it would be a great time saver for our projects if there was a function within Revit that would allow us to produce these efficiently. A further application could involve our Bridge teams as they are starting to use Revit more but are also finding it limited for developing complex elevations and section.

 

Has this request been raised with Autodesk before and if so was there a technical reason it could not be implemented? Or is this somewhere on the Structural road map?

Same for bridges

This would be extremely helpful!!! Please make this a priority by allowing the elevation to follow the face/centerline of wall. Been waiting for this feature since 2008!

 

We have to go and manually draw curved wall elevations to callout information and dimension elements in a drafting view... A huge waste of time that happens on every project with curved walls! With the amount of curved walls both firms I have been at put in projects, we might as well be using autocad with all the extra drafting we have to do to manually draw these conditions!!

Creating Curved Sections

Hello,

 

The subject come with the interporality between Civil 3d and Infraworks but works with buildings too.

 

When you modelise bridges it is common to have curved bridges.

 

It is impossible to create OOTB a curved section at the alignment of the bridge and the only way to do it is to export the bridge to civil 3d and reimport the dwg to Revit but it is not dynamic if you have to modify the geometry. So it is not BIM !

 

It could be great to have the possibility to make curved or unfolded cross sections not only with bridges but with curved walls.

 

Thank you

Developed sections are mandatory for bridge detailing.  It is a standard requirement to have a section on the alignment of a bridge, and bridges are often curved (NB: Alignments can contain a combination tangents and curves). 

 

Same applies for curved tunnels and retaining walls in Revit - we need developed sections along the alignment.  

 

The workaround is not BIM (exporting solids to C3D and re-importing a flat 2D CAD file into revit as a detail/section). 

This is a critical flaw and if Autodesk wants Revit to be used for bridge detailing, this has to be addressed natively.

We NEED this

I don't need curved cut lines, but buckling is sometimes necessary.

Then I have to help myself by stitching several sections together, just as shown below.

Couldn't there be a more elegant solution?
