Create Lane Marking

[Anonymous]

Hi every body,

I would like to create a lane marking and I can not find a solution. The lanes are in an Autocad file and are drawn as 2D polyligns and it's not possible to extract contours to import them in Infraworks.

would you please help me to find a way to solve this problem?

This solution does not work : https://www.youtube.com/watch?v=KY5yGxtoljQ

Thanks,

Hi Haykel2013,

I recorded a screencast showing you one way to quick and dirty bring your markings from AutoCAD into Infraworks. It is uploading right now and as soon as it becomes available I will post it here. This is one way of doing it, and I hope it works for you. 

Let me know whatever the result is, hopefully it will solve your issue, if not we can take a look into other possible solutions.

Hi @Anonymous

in the video the lane markings are 3D solids in AutoCAD and the exported as FBX. That might cause issues if large coordinates are used.

From my point of view it is easier to export the lane marking polygons as shape file (MAPEXPORT).

In InfraWorks import the shape file:

• Either use them as "coverage" and place the with an slight offset above the ground
• Or use the shape as "barrier" - this way you can assign a barrier heigth of few centimeters

Hi Karsten,

The only solution witch works well is to use the shape as Barrier but it takes too long time as I have different types of marking lanes.In fact, I must difine all the types as 3D models and use the exact spaces between the Barriers...

The easiest way is to import the shape file as polygons but I can not find a solution to create polygons from 2D polyligns in Autocad. The lane markings are about 7km length and I need to extract the contours from 2D polyligns (drawn with different widths).

Can any one help me to extract those contours witch will make my work much more easier.

Thanks fo all your replies.

Here is the screncast, sorry for the delay as it took forever for Autodesk to authorize it use. It looks you found a solution. Great bud!

Oscar,

Is there a reason you choose to go the .SHP route instead of the .SDF route?

[Beka_Tchigladze]

what about if I want to add markings on the component roads? you cannot import shape as a coverage area in that case

[Karsten.Saenger]

Hi @ocastaneda ,

you can use SDF as well.

Karsten.

it is top of terrain but not top of the road I cannot see it until erase my component road

[Karsten.Saenger]

Hi @Beka_Tchigladze ,

for component roads, the workarounds is to use 3D objects directly - I am aware that this is not ideal for longer roads.

Or you use 2D polyline stripes and import them as barriers. Ideally you have a corridor surface to drape the 2D polylines on.

Regards,

Karsten.

Just a personal preference. I have worked with shape files for so long that I am used to them. I hope this helps!

You are correct. This is one of the most frustrating things with this program, Infraworks is terrible with some common tools you would expect to have such as pavement markings. Coverage areas as a way to bring data on top of your roads will not work if they are component roads. 

There is a way to do this which is cumbersome and tedious (like many things with Infraworks), Jeff Bartels did a video showing how to accomplish this and is very good, I encourage you to check it out as it works for this particular purpose, here is the link:

there is much easy way also, if you have all marks in autocad you can export areal image from Global mapper and import overlap image in infraworks. if you have complete model you can do this. but it is not convenient again.

infraworks team must do theirs job better, otherwise it looks like as a kidding garden, because it seems that they are lazy, software need too many many updates and fixes. sorry but it is reality i like autodesk but it is reality.

Ok, wild idea.

Why not round-trip it via IMX. Export your component road as IMX, then re-import it into a new proposal (with your component road removed). Then you have a surface you can drape your SDF format markings on.

Sure, it's no longer a component road, and you may need to reapply textures to the road surface as draped coverages, but the marking should look really nice.

I've done this before with some decent results.

I also have a nice routine that builds perfect markings based on CAD layer or line styles/type, giving them the appropriate width and colour .etc

If you can post some data, maybe i'll take a look.

Good luck out there...
