import file from rhino to vektorworks

[XeniaLee]

I need to import a 3d file from rhino to vectorworks. Its a 3d city map and I only need the street map as 2d. I tried a lot of variations, best so far was delete everything i don`t need in rhino, export it as 2d dwg file and then import in vw. The import works, the streets import as single lines (which is annoying but i can redraw them theoretically as polygones), the problem is that vw freezes after importing the file and stops responding for hours until I force the program to close. The file is about 0.5 mb so this should not be the problem and I am seriously out of ideas, I tried to import this for days. Changed a lot of settings but always get vw frozen after import or crashing whilste import.... any ideas?

Can you post the City map file here.

I bet we can take a look and figure out what is causing the hang up.

 

Also, you can import a Rhino file directly into VW as 3D,

Go into a plan view and "Convert> convert to polygons" to collapse it into 2D

then, use the polygon tool with the bucket mode to quickly convert areas to composed polygons.

yeah I know, i tried to directly import the rhino file in 3d but it keept crashing at import. so i tried dwg instead. i successfully imported the file as 3d dwg file, but the streets then turn into 3d nurbs (which caused a lot of lagging but at least no freezing). i tried the bucket tool on the 3d nurbs, but it was not working, so i was thinking of directly import the file as 2d...

here you can find the original rhino file (withouth terrain, because file was to big for upload) and the 2d dwg file (the one that i tried to import to vw that keeps freezing). i have rhino 8 and tried vw 23 and 24 (both not working though)

 

thanks for your help 🙂

When I imported your file, it had two models widely separated.  I put them closer together for viewing.  The pink version are 2D polygons.

 

Just so I understand what you are looking for, is the 2D portion something you are interested in?

i am a litte bit confused about how your file looks like...

the rhino file should look someting like this. and what i need is the road and the curves layer

I also looked at the file.

The Rhino import to VW brings in proper 3D Solids of Buildings.

(I think the pink curves on the site were just loose 2D Lines)

 

But the outline DWG export from Rhino is pretty much useless.

It is also just loose Lines but these somehow appear as Solids.

Problem is that there are no top or bottom Faces,

which you could use to extrude them.

But there are only the Lines around the street's side faces,

and unfortunately from rhino standard, with these extra

NURBS control lines.

So if you select them from top, each Line segment is in fact

3 Lines + vertical lines at each end.

 

As you have access to Rhino, I would separate the streets

and try different export options, until they finally export

as Solids in DWG.

 

[zoomer]

Somehow I lost your curves but these are in the DWG.

 

Buildings, Roads and River extruded,

Site Islands just closed Polylines.

@XeniaLee  Looks like Zoomer has you fixed up ,

 

@zoomer  I had two files as I showed.  Did you only have the one?

[zoomer]

I looked at the files last night.

Imported Rhino into VW 2025,

checked DWG in Bricscad.

 

Wanted to look at Bricscad again today to see if I could

get Boundary Selection from the Street Line Crap,

but that was not possible.

(Bricscad too felt a bit slow with that file in general)

 

Then I looked again into VW and saw that I filled a few

of those sites with Polygons by bucket mode.

(That part was very laggy in VW)

When trying to complete them, by making an outer bounding

rectangle around the opened outer sites,

I realized when hovering, that there was a (hidden) Street Object

as a Solid (?), at least I could not make it visible from attributes

and fill color.

 

But I could extract its top face, which I could also extrude.

ITS all about nurbs, what comes Out of rhino. Even a rectangle with rounded edges was a nurbs which i could Concert into a 300 Point Polygon.

[VIRTUALENVIRONS]

There is one export format I have used extensively in the past with Vectorworks.  Parasolid X_t.  The models came in as if they were made in Vectorworks.

Rhino now exports that format.

I did a test with Rhino using a small NURBS file.  The formats below all produced the same file in Vectorworks, but you can see how much smaller the X_t and other files are.

X_t > all, because ITS the native language of all 3d parasolid modellers, topsolid, Solid Edge Solid works.

 

Not good, is the Export x_t of vwx.

 

I am Missing the names of the objects, the colour and the group structure 

 

 

[KingChaos]

My Partner exported rounded rectangles, 8 Segments If done with vwx. 4 Linea 4 circle parts, but the parts are Not orientated in x y or z, they are angled and declined, so some rounding mistakes making IT a 400 piecea Segmentes polylinea If i converted them. Totally inacceptable for milling them die n Our CNC.

Got your PM, responded.  Can you post the original Rhino file so we can see what you are dealing with.  Others may chime in with relevant experience.
