Batch export DWG from Revit using Dynamo!

[@AussieBIMGuru]

Correction: There is a free tool that can export as well as rename DWG - ProSheets by DiRoots! Check it out here if you're interested; diroots.com/plugins/revit-to-pdf-dwg-dgn-dwf-nwc-ifc-and-img-prosheets/

Thank you very much, I adapted it to my needs, it was a great help, greetings from Colombia!!

Of course Gavin got the fair dinkum script for me!

Glad it helped, strewth!

Hi Aussie. This is an incredible script you've created. In my Revit 2019 something is happening in between the snu/sna code block (which works fine to show the list of my sheets) and the Multi Input Form, where the UI pops up but there are no sheets listed. Do you have any idea what might be causing that? Best regards

[@AussieBIMGuru]

Hrm hard to say, Revit 2019 is very old now so I suspect the package is no longer tested there. Might need to take this one to the forums potentially.

@@AussieBIMGuru Thank you very much for the prompt reply. Appreciate the advice!

Hey Gavin, Out of Topic Question. But it's about exporting 😁. Do you know what's the difference in the IFC file exported from ArchiCAD Export Addin with Revit's default? The client requested specifically from that add-in and I'm not sure how to emulate that from Dynamo.

[@AussieBIMGuru]

I believe it has slightly more efficient results - I don't believe it is different RE information exported (depending on how you've set up your data anyway) but in my experience the geometry is usually more complete and less errors occur from that plugin.

[@ErwinMeulman]

There is only one way, from revit to dwfx for 2d and 3d nwc or ifc, when the building is built make some pdf/a1. When you build a dwg, build them in the same place as the 3d model, so in XY-plane and XZ / YZ plane, only Tekla I now that have some option. But with dynamo....

[@AussieBIMGuru]

In this case the Dynamo export is using the same export options as Revit itself, so the internal/shared coordinate system is essentially managed in the same way. I'm aware of the challenge you've mentioned and as far as I know making sure the internal origin is coincident with other authoring programs is the best method. Almost never ends up being done this way unfortunately.

Good script Gavin...!! Can you make a video on how to batch link cad and Revit files at once...It will be helpful if you add it to your bucket list..🙂

[@AussieBIMGuru]

I would check out the thread/workflow here as a starting point - someone may have solved the DWG component of the workflow already. forum.dynamobim.com/t/link-multiple-dwgs-create-drafting-view-for-each/48449 RE Revit files, there should be a few packages that can do this, some are discussed here; forum.dynamobim.com/t/batch-link-in-revit-models/33999/6

[@ravichandra-up1nu]

Thanks a lot..!!

[@kevinsun-sothi3693]

is it possible to export a sheet with shared coordinates in addition to what you show (not possible with Revit) ? Thank you and congratulation for this video

[@AussieBIMGuru]

Not that I'm aware of, just views as far as I know.

[@william_78]

Nice, Gavin! Can I do the same to export pdf?

[@AussieBIMGuru]

There is a node in the same package for printing PDF.

[@sujanmaharjan9182]

There is a node in the same package but for naming you to need to some tweak in your PDF export driver I like to use PDFCreator and adjust Filename and FileDirectory setting.

[@Martim89]

That's very usefull and seems to be clear. But where I can find the way to produce thos two nodes? ('DirectoryPath Data' and 'Listview Data') If you could explain that part or to refere to any previous video of yours that would be amazing. Thanks

[@AussieBIMGuru]

You need data shapes for those nodes. I discuss this at 1:15.

[@waitpethk]

Hi Aussie, may I know are there have anyway to manage Link Revit Model to Export DWG with different Layers order? Because we used serval link Revit Model into a Sheet Files and the order of the Link Revit Model became a BLOCK in DWG. And the Block in DWG were in a wrong order (Which I cannot find anyway to control). Thanks

[@AussieBIMGuru]

Not that I am aware of. It might be a matter of using LISP to rearrange layers in AutoCAD afterwards as Revit has limited DWG export ability.

I am looking for 3D views export to CAD for multiple Revit files. What kind of alteration need to do to get it done

[@AussieBIMGuru]

This workflow should also work for 3D views. If you need to do multiple Revit files at once you would need to use an 'open in background' process. Such nodes can be found in the orchid package.

[@maciejradwanski406]

Hello Gavin. Did you ever face a Shared Coordinates problem when exporting? I mean when you export sheets its always loosing correct UCS.

[@AussieBIMGuru]

Usually it comes down to how you set up your origin in Revit versus AutoCAD, and the project vs true north rotation. I've found some projects will work, others wont and usually it's because the internal origin isn't in a good location in Revit versus AutoCAD. There doesn't seem to be a reliable way to export between the two in my experience as getting the internal origin right is difficult in Revit given it isn't movable.

[@kamronsullivan5720]

Anyway this can be done but with NWC Flies instead???

[@AussieBIMGuru]

Hrm possibly... I usually just use DiRoots ProSheets for this task these days - free and easy!

[@kamronsullivan5720]

@@AussieBIMGuru Can that Add In export the views in the background without having to open revit

[@AussieBIMGuru]

@@kamronsullivan5720 no. You always need to open a model to do that (even if in background). Forge might be able to do that but you'll need to build the tool

[@PANDURANG99]

Not. Support to BIM 360 model

[@AussieBIMGuru]

Yes for BIM360 automation you will need to look into Autodesk Forge services.
