Hi, I encounter the following problen, which I unfortunately cannot solve: I have a DWG-File containing 13 closed polylines (see the figure). ![](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/d/2/d286268a33bd94296fd632e14e93a7315f21c350.jpg) After I import the file into Revit, some of the polylines are sticked together and will be recognized as one line in case of a query. E. g. these two: ![](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/c/5/c5c2331bcf3b61ca63d441f65891d06a714803f2.jpg) You find both dwg-file and rvt-file attached. [polylineproblem-2017-02-28.dwg](https://forum.dynamobim.com/uploads/short-url/8OalIwKjhTOhSLsVXvfpF9PAcNn.dwg) (40.8 KB) [polylineproblem-2017-02-28.rvt](https://forum.dynamobim.com/uploads/short-url/2zaQvoeO4JWQqssGZRdWkihxJ0k.rvt) (328 KB) The background of my question ist that I want to work with the geometry of these 13 closed polylines, I want to get their geometries (polycurves) in Dynamo in order to construct floors. But revit reconizes fewer than 13 polylines. I would be grateful of any help? ---

Hello babysatch, I stumbled upon this helpful video which seems to do exactly what you are looking for: [https://knowledge.autodesk.com/support/autocad/learn-explore/caas/screencast/Main/Details/7ccb54c2-693f-4b27-bebd-7331d0530dfc.html](https://knowledge.autodesk.com/support/autocad/learn-explore/caas/screencast/Main/Details/7ccb54c2-693f-4b27-bebd-7331d0530dfc.html) ---

Hello T\_Pover, do you know how I can download the lisp-file from the screencast? In my opinion it is not available at all, is it? Thank you. ---

Hmm, I dont’t know about that Lisp file. You could try contacting the author of the screencast. ---

> [@babysatch](#): > > how I can download the lisp-file from the screencast? Another way to do it would be to get data out of AutoCAD and write it to a text file. Then read the data in Dynamo. From the video, why would we want many Floors for one level? Wouldn’t a better, old-fashioned, way to make the floor be to pick the outer lines from the DWG in the floor sketch?
