DESCRIPTION
Convert curves from a CAD Link or Import to Dynamo curves or Revit Model Lines using the file layer names as a filter.
Layer names can be input to filter and convert only curves on those layers. Curves are output in sublists based on their layer name and mapped to the Lines Line Style to prevent unwanted CAD styles from entering your Revit project. Alternatively, Line Style names can be input to map each sublist to that style during conversion. To convert all layers, leave the layerName input unconnected. Input layerNames and LineStyleNames are case-sensitive.
The node is optimised to convert curve-types that typically fail when using Dynamo’s Element.Curves node or Revit’s Explode tool for enhanced performance. The node also circumvents the 10000 element limit set by Revit for greater workflow flexibility.

USER GUIDE
Dynamo Nodes 
Amazing tool!!
Only limitations are that it does not work with 2018 so I had to use 2017, and that to use a sketchup model, it only converted the lines found in plan projection, and no “vertical” lines, not that I’m complaining 🙂
Thank you!
Hi Basam
Thats correct, there have been changes to the API in 2018 and we’re in the process of updating BimorphNodes so it use’s the new methods. Expect BimorphNodes v2.1 update release in Q2/3 of 2017! We test using DWG and DGN, so compatibility isn’t guaranteed with other file types. In the meantime, you can export your Sketchup model to DWG as that will work. We are always looking to make BimorphNodes even better, so if you can report the problem on the BimorphNodes GitHub and share an example file, we’ll look at the issue: https://github.com/ThomasMahon/bimorphNodes/issues
