Element.Geometry returns null in more than half of the floors that I need to work with. I have to get to the top surface of the floors. All floors are sloped, with modified sub elements. ![floor%20null%20geometry](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/0/0/00ab8a0474a6210cd90896e06b3d69d3888c5154.jpeg) Changing the working range would result it changing percentage of null values, but won’t get rid of them. (S - 43%; M - 40 % L - 20 % XL - 92% of elements return null geometry). The problem is not with the working range though, as some of the elements don’t return any geometry no matter what, even isolated in a new project. ![error%20floor%20geometry](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/d/f/df11f266f0fd02632f084d2c89397d4d15482d84.jpeg) Any ideas how to get to that geometry?

I had a similar problem when the boundary lines of a floor were very short in some part of the floor, or the angle was too sharp. Maybe try to simplify the boundary lines? ---

Hi @rastermadre Looks like you have planar shape floors. Try using “Springs.Collector.Element.Sketch” node from spring nodes package. ![](https://cdck-file-uploads-us1.s3.dualstack.us-west-2.amazonaws.com/flex022/uploads/dynamobim/original/3X/e/5/e5439ec26cdd56ae59addc9c0f3eb6161adbfea4.jpg) ---

not it, this one couldn’t be more simple, but the geometry is still null. ![floor%20boundary](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/c/5/c5d958576c5e3a15024d8bf612293c4ea34b3cf8.jpeg) ---

my bad, i should have mentioned that I need to get to the top surface of the floors. thanks for the node suggestion though, will come in handy in other situations. ---

Thanks, it worked But in search for the top surface I’ve found my answer here: > [@Modified Floor Top Surface](https://forum.dynamobim.com/t/modified-floor-top-surface/16196): > > Hi all, I was trying to get the surface of the modified floor points but still no success. as a start please see attached images of what im trying to do. Thank you. The Python script proved slightly more accurate, although it’s not 100% precise with the floors cut by floor openings.

Hi, try exporting a SAT file from the view then importing the geometry back into Dynamo.
