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.

Please also allow an option to include column grids which intersect the view depth to be displayed for reference.  I anticiapte that you might need to implement a "parallel offset view depth" option so the curved view cutplane and depth plane remain consistent.  Whichever grids intersect this cutplane would be rendered.  At least make them show up then we can element hide the ones we don't want to see.

to have the ability to create a curved section

 

Hello

It can not be a standard

But the technique can create mass
then join mass with revit elements.

 

curved section

When using revit for Structural build objects (Brudges/tunnels/and so on) there are many examples where the project demands an perpendicular view of some objects. For example the walls of a tunnel.

A example of why they want this is so they know where the cast-in items have to be.

 

Nowdays these drawings are still made by hand in autocad...

 

please.. support sections or elevations along an curved path.

Revit has many features which are usefull for bridge design. It would be very usefull if it would be possible to create section along curve. According to many forum threads users are missing that feature also for other applications. Another idea is to implement tendons like rebar shape.

 

Following videos show the functions that I have in mind:

This would aid immensely in CD phase with curved buildings. From a construction point people want to see the "flattened" version of a curved wall in elevation (otherwise one can't measure on it). In 2017 one still has to make those kind of views by hand, and that's a very tedious and time consuming task.

I'd like to add that it shouldn't be limited to just one curve. What we basically need it being able to make a section or elevation like a 'polyline' (that supports linear AND curved subsections). 

 

In Belgium, we call these types of elevations/sections 'flattened'. Basically, you project everything against a chosen polyline 'surface'. Right now, that's a fully manual job in cad, that takes a lot of man hours and has to be completely redone from scratch when there's a significant design change.

To create sections using poly line or curved line/axis.

this will help in adding details - drawing extractions for model curved towers , cylinder stairs , block walls.

 

For MEP "long sections" are a similar thing. This is the straightened out section along a pipe, even as it bends, so you can see its relationship to other pipes that pass over and along it and to the ground above. As per @pieter1, this requires a polyline path with linear and curved parts.

This improvement would be very important for German Revit users. It is even very important for infrastructure projects for a representation along the longitudinal axis .

In the Revit Wishlist 2017 in Germany it ranked #8 out of 52 wishes. You can find more information on https://www.rug-dach.de/

I agree.  If Revit really wants to get into the infrastructure game, these flattened curved sections are a must for bridge / tunnel projects.  I have been waiting for over 6 years for this one...and still waiting.

Yes. we need this feature

Why We Can't Take a Curve section?!!

Because geometry

We've been building curved stairs for centuries without curved sections. A curved section would only be a geometric abstraction anyway, and would probably confuse the contractor to no end.

Instead of curved section may be better to do a wrapping surface, for example, room's bounding walls.

Not sure how a curved section would work if the view has any depth at all. The stairs beyond the section mark would have to ... there would be multiple vantage points ... looking in different directions at the same time... Wait! ... I think I finally understand Cubism! Thanks!

 

In all seriousness,  and I know this is Ideas not the Q&A forum, but this is when you use a drafting view to draw the stair run in section.

This is 100% needed for bridges.

Curved section: Is it possible to draw a curved section in Revit in order to show curved walls and ramps.

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.

Enthusiast

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

Participant

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?

Dear all, 

 

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

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。

Advisor

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.
