Tilting objects on a 3D Line

[zottt]

How can I tilt objects (city furniture) along a 3D Line (Exported from civil via sdf). So for instance a guardrail will follow my 3D Line instead of putting horizontal objects after each other.

To apply tilting, you will need to use the City Furniture as a road decoration. Once the decoration has been added to the road, the Stack will show a Tilting option. This happens two different ways:

For Design Roads, add the decoration to the road style and then apply tilting: https://forums.autodesk.com/t5/infraworks-360-infratips/road-decorations-use-tilting-to-follow-the-v...

For a component road, simply Place a Decoration (http://help.autodesk.com/view/INFMDR/ENU/?guid=GUID-2EEB449C-18F4-4342-AC91-BFC57A721141), then with the decoration selected, turn on Tilting in the Stack.

Note that vertical decorations such as lamp posts will not apply tilting.

One other great option if you .SDF guardrail profiles, is to add them to a design road style as custom profiles, which will follow the road alignment without tesselation, You can read how to do that here: http://help.autodesk.com/view/INFMDR/ENU/?guid=GUID-D22FACFA-529C-4C8A-9CB5-5A91AF0BEB3F

I tried that, but the problem then is that it may interfere with roads I have in my model..

Hmm. I wonder if creating a null road style that doesn't have anything in it but a decoration would do the trick. Would you be able to share a screenshot of your use case?

Thanks,

Hi Elliott,

Thanks for you reply! I used it as a road style and it works. 

There are some issues:

-how do you deal with guardrails on bridges (create a new style)

-at the start/end of a guardrail, I want te let it dissapear in the ground, when using a roadstyle it'll change my groundsurface

-a guardrail is technicly not a road, so it should be shown as a city furniture

Hey Zottt,

Glad you got it working!

As to your questions:

-how do you deal with guardrails on bridges (create a new style)

For design roads, the bridge exists underneath the road, and is assigned a road style. Therefore, you can use a road style that has been stylized as a bridge, such as Street/Bridge Deck/Simple Barrier (pictured below). If you want, simply change the road style to reflect the decorations you want to use.

For component roads, you can place a guardrail decoration, adjust spacing (I use 3m instead of 10m), and turn on tilting.

-at the start/end of a guardrail, I want te let it dissapear in the ground, when using a roadstyle it'll change my groundsurface

I dont think we currently support this type of workflow, but it is a good idea. I would consider adding this to the idea station.

-a guardrail is technicly not a road, so it should be shown as a city furniture

Agreed. In InfraWorks we consider road decorations to be additions to a road. But you've got a good point there. Where are you seeing it 'shown' as city furniture?

Thanks!

This issue came up just last week where a fence from a two-tone (black and white) image was created as a barrier. I knew that the tilting was available as you have described but that option would be nice to have for the barriers as well where the fence element was placed. Perhaps I should place this thought into the ideas section.

[zottt]

When the tilting can be done in Barrier styles, this would be the best solution!

I managed to take a raster (attached) which is bi-tonal (the background is "transparent") and extract polygons / polylines from it using PCI Geomatica (I do not know yet if AutoCAD Raster Design can do this but I have asked that question in that forum).

From there, the data extracted  (in the DXF format)  is converted to AutoCAD regions, has constructive solid geometry tools applied (Subtract) and then a 3DSolid is created after the Extrude command is used in AutoCAD. From there, an FBXExport with materials (Black Paint) is then brought into Infraworks as a 3DModel from the FBX file. The 3D Model is then applied as a decoration of a Component road (the decoration can then be "tilted" with the land surface). The road lane in the example below has to be replaced with a transparent material which I can do for a Design Road but as of yet, not for a Component Road.  Anybody know how to add materials / elements to the Component / Assembly folder?
