Create DWG from 3D ArchiCAD

Anonymous — Fri, 23 Mar 2012 20:28:02 GMT

Hi.
Is there a way to take a 3D view in to AutoCAD as a DWG?
I am hoping to take some line drawings of my perspectives and axonometric in to AutoCAD to further edit.
Obviously it will be flat right?
Thanks.

Not sure why you'd need to go into AutoCAD... but if you are in a newer version of ArchiCAD (13 and up?) you make make a 3D document of any 3d view. That view can be exploded in archicad and turned into line work for the editing you'd do in AutoCAD.

Or conversely you could just do a save as DWG from the 3D document window.

Next week or the week after I'll have a blog post up that uses a similar process to take linework into Illustrator.

Thanks, this seems on the right track. Just how do I 'explode' whilst in 3D Document view?

So I have an artist that is going to produce a rendering for me. He wants a DWG file of my 3D rendering view that he will use in his workflow with a Piranesi EPX file. Though these prior posts discuss saving out a DWG from a 3D view and exploding a 3D document, I have not found a way to execute either. Saving from a 3D view results in a DWG plan view. Am I missing something?

You can save from the 3D window directly as a Piranesi (.EPX) file.
I don't think you need any special add-ons to do this.
At least I don't recall installing any apart from the standard add-ons from the Graphisoft web site.

Yes, I'm aware of that. What I'm unclear on is how to save out as a DWG. Don't ask why I need to do that. It's just part of the artist's workflow.

Dave,
To save 3D *.dwg file open 3d window and do a save as with the window at the front and select dwg as the file format, 3d dwg saved.

Best of luck

One would think that to be the case, but give it a try. What you get is a DWG of the floor plan.

Just did a Save-As from the 3D window and it works.

OK--this is weird. I can't figure out what settings I have different than you. I've tried three times and only get a plan view dwg.

You are opening the 3D Window and doing a save as from there?
Not publishing or saving from the floor plan?
----
If you open the file in Autocad(if you have it) or in Draftsight (if you do not) take in consideration that it will display the model in "top view" and in wireframe.

Bingo--thank you. I use SolidWorks eDrawings to view and didn't realize that it was displaying the 3D model in plan view. So now I realize that even though I can get a dwg of a 3D MODEL, there is no way to match the exact VIEW from the AC 3D window. I also can only get a parallel projection, as the perspective option is greyed out, but maybe that's a limitation of the viewer I'm using.

Yes. It's just the viewer. I don't know any way to export the camera viewpoint though. You could place a marker (an arrow shaped slab or such) and the artist may be able to set up a view from there base on your perspective settings. Since none of us know his process it's hard to speculate.

Thanks, Matthew. I was thinking I was exporting to a 2D DWG file of the camera view. Seems odd to me that is not available. Even I don't understand his process using the 3D DWG file, but I am giving him an EPX file, as I want the base work done in Piranesi.

For a DWG of the 3D view you should be able to save that from a 3D document window.

Yes, but there seems to be no control over the size of the resulting image--no?

I just checked and the 3D Document saves DWG to world dimensions at 1:1 scale. You can reset the scale to match the output size.
