[Resolved] Importing 2D .dwg overlay

Hello All,

I found an old post from 2013 that kind of talked about it but I am trying to import a 2d .dwg plan from AutoCAD0 to use as an overlay. We do a lot of masterplan work and this would REALLY help us layout big project.

Has anyone solved this yet?

Thanks in advance!

Hi MPJohnston85

Lumion is not able to import 2D data, only 3D data. 

You could create an image or screencapture of the 2D plan and import that as a texture (Color Map) to a surface to use as a base for layout.  You would need to get the scales correct.

As you will probably need to be modelling context and buildings in your 3D modelling application, you are likely to use that masterplan anyway.  So if you can convert the 2D dwg to an image/PDF for modelling against, and then have that laid out as needed in your model to a surface, you can then import that to Lumion. 

What 3D modelling software are you using, and also which version of Lumion?

Yeah, those scales are tricky. I'll give it another swing.

The plan was to model the landscape and site work in Lumion and place individual models onto that. I just wanted a way to know I was placing things at least somewhat accurately.

I like the more natural look of the Lumion vs. Revit toposurfaces.

I am using Revit 2018 and a Lumion 7.5 trial. Testing to see if the software works well for our company's needs.

Thanks for your help pererm! Hopefully I can figure out a nice solution.

OK, sounds good although sorry yes, there's likely a little work to get the plan scaled correctly.

If the 2D DWG is imported in Revit, then you have your masterplan for layout.  From there add a surface and map a screencapture from Revit of the 2D plan.  Then the surface will import as a 3D object to Lumion form Revit.

Perhaps some other users in our community may also have some better ideas than I can suggest.

Please be aware that the editable part of the Lumion Terrain is a square of 2000mx2000m.  If any part of the plan is outside that area and you need to model the landscape, then unfortunately you will need for it to be done in the topography tools of Revit (or SketchUp if you also use it).

ps: Are you aware that there is also a Pro Trial version that is for the current v8.5?  See our Knowledge Base Article: Is there a Trial version of Lumion?

I do not know if I can help, but Autocad has option between plots, the option to export png image, which can be configured output in the format 10000x10000px.

This image if adjusted in an image editor to fax the transparency channel, can be applied to a 2d plane with the right scale in Revit and imported into Lumion for reference.
