I get this error UNCONNECTED LINK SEQUENCE (WARNING W2000). I’m new to AutoCad and Dynamite VSP & I’m not sure what this error means.

This is nothing to worry about - it is just a warning relating to the application of UVW mapping to sequences of links in each subassembly.  For more information on UVW Mapping, refer to the 3ds Max Design documentation.

It’s just trying to warn you that the texture mapping results might not turn out as expected.

Let me try and explain what this means.  Take a typical subassembly - a kerb and channel for instance.  What the exporter tries to do is drape a kerb texture once across all the “top” subassembly links. In this case the channel, kerb face, and top of kerb.  We call this ability to drape a single texture across multiple links “span mapping” - mapping coordinates that span multiple links.

Span mapping can only be applied across a subassembly, if the links are connected to each other - i.e. there are no gaps between the links.  If a gap is encountered, the span mapping sequence is broken, and this leads to the W2000 warning being displayed in the output log.

In most cases this is not going to be important to you, but we inform the user of the result just to make you aware of what is happening.

This is all very technical, and requires a good understanding of the structure of subassemblies and link codes in Civil 3D - but I hope this makes sense?

I think I understand but when I import it into 3ds Max Design I don’t get lanes, I only get lines. No renderings.

Are there any corridors in your civil 3d drawing?

Yes. It’s a neighborhood. Probably about 5 corridors.

OK. I’d need to see the drawing to understand why you don’t see any surfaces in 3ds Max Design.

Do I need to email the 3ds Max file to you?

It’s the DWG I need really.  If you don’t want to part with that, the VSP3D file you generated would partly help.

If you would email me .(JavaScript must be enabled to view this email address) then I can attach the dwg file and send to you.  I really need help. Thanks.

hi,

when i export my civil3d corridor i doesnt look like a road in 3ds max, it comes out like a surface. in civil the assemblies look nice. anyone knows what im doin wrong?

when i try to connect vehicles to the alignment and push play for animation in OPS editor, the cars moves in mysterious ways! they dont drive straight forward, nice and smoothly, instead they dances around. it looks like they cant find the proper surface.

anyone help me, please?

I’ve just loaded your DWG file, exported it to a VSP3D file, and imported it into Dynamite VSP.  I am seeing the surface of the roads in 3ds Max. I just imported everything from all the corridors, and excluded the surfaces from the import.  Corridors generate their own surface for each region in a corridor.

Here is an example of what I see in my viewport. Are you not seeing the same result?

Try excluding the surfaces from the import stage in Dynamite VSP. During export from Civil 3D, the exporter generates it’s own corridor surfaces which are split by region, and have all the correct material assignments. If you have generated your own corridor surfaces in Civil 3D, and include these in the export as well, you will have a duplicated corridor surface. Civil 3D “surfaces” are not intelligent, and know nothing about the subassemblies used in the corridor (unlike our exported region based corridor surfaces that you’ll see in all the demos).

This sounds like your model has been imported too far away from the scene origin in 3ds Max, which can cause inaccuracies in your imported data. Dynamite VSP is designed to take care of shifting your imported civil model towards the scene origin automatically, but it requires a clean max file for this to work.

There is a chapter on this in the Dynamite VSP help file. Search for “global import shift settings”.

What are the XY extents of your model in 3ds Max?

hi,
i excluded the surfaces when imported into dynamite. i didnt work as i was hoping it would. all that was imported in dynamite was the alignments.

i think there must be something wrong in my corridor-settings. can i email the dwg to you?

Rune, I received your e-mail. It all looks fine to me, and the result I get in DVSP is as expected.  See attachment below, are you not getting something similar to this?
