Hi - I am facing a (rather) weird issue. My intent is to create a basic set of floors such that the outline (which is in flux) can be quickly changed from CAD to BIM. So there will a bunch of CAD files; linked into the Revit model at corresponding levels and one dedicated CAD Layer which will inpu…

It might be the fact that importInstances wrapped in the Dynamo Revit.Element class are “UnknownElements”. Its been reported on the GitHub. I’ve also looked at your DWGs and the level name you are inputting doesn’t exist in these files, hence you wont get any curves!

Hi @Thomas_Mahon Thanks for the quick reply [image] Thomas_Mahon: It might be the fact that importInstances wrapped in the Dynamo Revit.Element class are “UnknownElements”. Its been reported on the GitHub. Does that mean it would be resolved later? Actually the screenshot was from the earl…

I meant layer name! To reiterate, in your DWGs there are two layers. Floor is the only layer in use, hence to extract the curves using CurvesFromCADLayers you need to input "Floor" via the codeBlock. Entering "215 Curtain Wall" will return null since this layer doesn’t exist in either CAD file. Alte…

Hi @Thomas_Mahon Thank u for sparing time to import the files & help out. Yes - I understood what you meant and reached the same state as your screenshot (the DYN had the correct input of “Floor” with the Curve extraction working). [image] Guess the Import Instances being “UnknownElements” is t…

Hi @Chandrasekar_Rajaman [image] Chandrasekar_Rajaman: Is there any other way I can input “Import Instance” without using “Select Model element”? Use Element types node. [image]

Hi @Kulkul Thanks for that - I tried that (as is visible in the screenshot) but for some reason, it throws a null when trying to extract the Curves from the CAD file…! Can you please take a look at the CAD & DYN files uploaded before?

@Chandrasekar_Rajaman Sure, I have a look later today.

Hi @Chandrasekar_Rajaman It is working as expected. There are couple of inputs you missed. [image] And here is the file Convert CAD Outlines to Floor Slabs(For Chadrashekhar).dyn (15.3 KB)

Hi @Kulkul Thank u for the reply & apologies for the delay in getting back If u look at Post#5, what I wanted to highlight is that if I select by Model element, the conversion works! But if I use All elements of Type, it returns Null. [image] Chandrasekar_Rajaman: Is there any other way I ca…

You might checkout Flux as well. They’re working on an AutoCAD plugin.
