AutoCAD compability with Dynamo

Hi!

I’m a new Dynamo-user and have just started to use it with AutoCAD Civil3D but I find myself struggling with importing simple AutoCAD geometry and converting it to Dynamo geometry.

Maybe I’m simply just not doing it right or is this so new that the compability isn’t there yet? I’ve looked for solutions on the web but seems to be hard to find.

Thankful for response from anyone who has more intel on this matter.

Hi,

check out bimorph nodes (package) for autocad compatibility.

Thanks, I installed it but it doesn’t show in the Library under Add-ons so I don’t know what nodes comes with it.

Did you install it with packages manager? Works fine for me… wierd

Hi @Sampa,

Try the following guide image below. Use object.geometry to convert Cad object to Dyn Geom.

Hi @Jowennl!

Thanks for the answers! I used those nodes earlier but it seems that my geometry was too detailed or too small, because now I’ve scaled it up and I got it to work!

Is there a limitation in how low fractions you can use? I was using geometry that was 1-10 mm wide in an (m) unit drawing. I get this warning:

On a completely other note, I think we met briefly in a bar on this years AU Block Party, :slight_smile:

Yeah, installed it from there, wierd. Got it in my packages folder and believe I can use the nodes too.

Hi @Sampa,

Can you please share dwg for testing purpose?

I did attend the AU block party and probably have met you there as well. So cool! Good to see we’re all back online again.

Hi @Jowennl !

Just because I started to prepare the dwg for you I got it to work with the small profile that didn’t work before (can’t say I know what I did different though).
However, im stuck now at trying to either:

-Get my Rail profile to rotate perpendicular along the path and the Sweep it to create a Solid
-Or copy/array my rail profile to given points along a given path (with points) and then Loft between them to create the solid.

is any of this possible (without connection to C3D corridor/alignment etc)?

I have only found ways to array Blocks and not how to array Dynamo Geometry, any clues?
I can attach the dyn and dwg that shows how far I’ve come.

Guardrail 3DPoly.dyn (109.4 KB) Guardrail.dwg (565.0 KB)

Thanks for the support /Simon

BiMorph requires Revit API so it likely won’t show up in Dynamo for Civil 3D. Same with Datashapes and many others.

LinkDWG will work though. :slight_smile:

Hi @Sampa ,

I would recommend you to check out the class I just did in AU2019. Many possible ways you can approach this and can be done by creating a barrier corridor as well. Can be done without corridor similar to what you are trying to do extrude to a path.

2019 AU Las Vegas Autodesk University Class: CES319333 – Dynamo in Civil 3D Introduction - Unlocking the mystery of scripting

Link to live stream recordings

(Refer to 25:07 - 27:49) - Tunnel from excel without corridor. This is similar to what you are doing but can be done. I did not explain in detail how I did it but show how it looks like.

(Refer to 36:20 - 42:46) - About Barrier and footings.

You can download the handout, presentation and data set in the AU website.

Cheers,
