Heya guys u might have known Ive started some architectual work, I know 3ds loves autocad, but i dont love 3ds.
I would like to know how lightwave works in this sort of field, its advantages, cons, what extra 3rd party stuff is needed that can help.
DXF files and autocad files i get alot of, how can i use them with LW?

Any great architectual lightwave sites out there?

I've imported AutoCAD, but not directly, I had to strip stuff out in Illustrator (yes Illustrator, it has a great DXF/DWG import/export) first because they had hundreds of layers!!!

I cleaned them up then saved out as EPS and then into LW, worked fine for me, and I had to do loads of sites!!!

For architectural renderings check the gallery:

Ahh cool...
I wish when u imported the autocad file it maintained the layers and colours of the layers.
When u import a dfx file into illustrator its a bit messy and needs tidying up.

You can import .dxf to lightwave, can't you?

DXF - yes you can

DXF into Illustrator, it never liked it when layers had hatching!

All i can see under import is EPSF.

You can open the file with modeler, no need to import.

I'm using LW for architectural work and can say that its DXF import sucks. It works, sort of, but depends on the file and complexity.

I started out using Vectorworks to convert DWG files, but with the advent of another new format from AutoDesk (and xrefs), I now have a PC running ACAD LT 2004 (30 day demo available btw). Exporting from that into Illustrator proves the safest route (if a bit time consuming).

The format that could REALLY do with being integrated into Lightwave 8 is PDF import:
In an ideal world I'd print to a PDF file from ACAD and import that (layers and all) into Modeller...

Just a side note, can we also import models done in C4d?

It's been a while since I've used C4D (v5), but no...you can't directly import a C4D file into LW. You should be able to export from C4D as .obj, which LW should have no problems with. You may even be able to export as .lwo now, though I wouldn't swear to it.

FWIW, if you're going to be doing a lot of converting of architectural files to bring into LW, it may be worth it to you to look into PolyTrans (http://www.okino.com/), and a copy of Virtual PC to run it. Both combined should run you around $700.

I export from C4d as a wavefront .obj file but LW refuses to choose it as its greyed out when loading object in modeller.

You need to switch the file type in the import dialogue box to "All Files". :)

Says unable to open file, well close to that nature.
Do I have to save it special in C4d like freeze the model or somthing like that before I export as .obj?

Hmm. I don't know. It's been a few years since I've used C4D (back before they had subpatches...HyperNURBS, whatever they're called now), and I never recall having any problems of this sort. Maybe try freezing it first. Also, do you have anything else applied in C4D like multiple UV maps or anything which might be giving it trouble? Sorry I can't be of more help...:confused:

I have imported AutoCAD file before, and currently I'm working a lot on translation to AutoCAD.
Basically, you can open DXF directly in Modeller, but you need to rotate plane.(it's about Y-axis world and Z-axis world) It doesn't matter what applications, Vectorwork, Illustrator, you need to open CAD file. The best way is you need to clean it until it has only information you really need. The good thing of using DXF is that you will get the scale you what. But in Illustrator, after you import CAD file in, the scale will fit on page you have set.
You should not have any problem to open DXF in modeller. But when you need to export it back, all objects that have more than 4 points polygons will be triangulated. It because DXF doesn't support polygons having more than 4 points.

Can u some how make lightwave recognise snap to point features as seen in autocad to 3ds and also c4d does it to?

For some ppl who are interested I found a good site with some interesting forums.
