Flattened curved elevations / sections

[angela_bachetti]

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.

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!!

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

[sophie.schilling]

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?

Dear all, 

We are expecting the curved section in this image to be attached (reference from youtube)

is there any script or other method? please suggest

There is an App for Revit called Bridge + Infrastructure Modeler which can be used to create unfolded sections by Revit command.

Have a look here for further information: https://docs.sofistik.com/2024/en/bridge_modeler/cmdref/shop_drawings/unfolded_section.html

在某些时候设计师希望通过对复杂的形体创建一个展开的立面视图来表达设计意图。例如从A到B 是一个由直线、圆曲线、样条曲线及缓和曲线组成的。这时想通过这条线（建筑物外立面外墙线）创建展开立面现有revit无法实现。

It is recommended that Revit can extend the curve to generate an unfolded facade.
At some point a designer wishes to express design intent by creating an expanded elevation view of a complex form. For example, from A to B is composed of straight lines, circular curves, spline curves and transition curves. At this time, I want to create an expanded facade through this line (the exterior wall line of the building's facade), which cannot be achieved in existing Revit.

Is it already possible to do it in recent revit versions? It'll be also a great improvement for architectural design. Thanks!

Hello, greetings to all, I recently came across a solution that worked for me, and that was to install the environment 

plug in and use Approximate Wall Path tool.
