Road markings From Civil 3D Lineworks

[Beka_Tchigladze]

Hello.

First of all thank you Autodesk that you gave us better road marking as before but!!!

I have a problem. I imported road corridor From C  rkingivil 3d but I have Road markings in a different DWG File because auto generated road markings through the assembly points was not useful for me and I need custom markings. I need them to import in infraworks. what can I do? I can export Lines as 3d sdf or SHP but I don't know what type of object can I import in Infraworks to get nice road markings. I tried to import as coverage area and give a buffer but it doesn't work. above the corridor. it draping on existing surface.

It's very hard to make custom markings look good on top of Infraworks road objects - due to the render order.

What I like to do is import my corridor as a terrain surface, and export discrete coverage polygons for each part of the textured surface.

A coverage for the road surface, then another on top for the markings.

For the markings themselves I use an SDF export, and interpret the lines as coverages with a buffer, or as polygons.

Alternatively I use a custom routine I built for making linemarking by interpreting the autocad linestyle and producing polygons with a hex colour attribute for mapping straight into Infraworks.

It takes a little discipline, however you can make Infraworks display markings that look great - but just not detailed custom markings using their planning or component road systems.

If you attach some of your data (road design & markings), I can demonstrate.

Thank you for your replay, I also like to import corridor as a coverages but I have bridge there also I want to add some guardrails and additional barriers there and by using coverages it will gives me headache, It would be great if somehow I would import my linework's, my only problem there is road marking otherwise everything would be great.

I typically split my road marking to a separate layer, and my barriers / decorations to a point or line layer.

I import my guard rails (lines) as a 'barrier' object, and my other decorations often as city furniture.

Sadly there's no really nice way to import custom markings onto the bridge deck - one option is extruding them to 3D objects, and moving them a few millimeters vertically.

3DS Max has some nice tools for similar kinds of work, via Autodesk's CivilView plugin. Worth a look depending on what your final output is going to be.

sorry I did not understand this very well,

So, At the end of the day I used barrier object in infraworks to create road lane markings. For continues and Transition markings I did not have a problem but for dashed ones, in the middle of the roads, I had a problem When I zoom in because of barriers are a bit longer with longer spacing in between them, dashed lane mark does not have enough space for smoothing effect when I zoom in. how can I get more clean dashed lines. apart from doing routine 3d boxes in 3dsMax on the places of dashed markings.

From the far enough it looks good but if you will zoom in a little bit it is a really crap.

Hello Beka, 

I have a similar problem regarding road marking : the 2D sources I have contains road markings in the form of polyline with specific styles to make it dashed. To import that in Infraworks I can't create polygons easily by extracting countours from the marking in the 2D source. I also tried to use the barrier in Infraworks but the result is not good either especially in the curves.

Do you have a solution to deal with road marks that are polylines with style in dwg sources ? 

Thank you very much,

Best Regards,

Abdelhakim

Can you share the workflow of "export discrete coverage polygons for each part of the textured surface" part sir.
