hello all, I supposed that the **Element.Geometry** node shows you the geometry but it is not true majority of times. > For example I got a revit file with a library of many different revit families of model categories as generic models, site, equipment, furniture and I got more 900 family types and **only 16 had a result of geometry**. > > ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/4/7/47907e9a957f3b82e37552e6bed25f29bd053b51.png) Therefore, I would like to know how to interrogate the families to get exactly the geometry embedded wether if it is solid, surface, mesh, lines, regions, symbols, points, inserted cad files, faces, whatever. > For example I had a deeper look to this truck modelled 100% with Revit family geometry, with empty geometry results in Dynamo, and I was expecting to get a list of all solids geometry modelled, if the geometry would be an imported 3d mesh I would understand there is no result, but this is properly modelled. > > ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/5/7/5709a0a8886cdb47c8df32d8a9b62538e1b4d2c8.png) > Family attached here for your test: > [BIMINONE\_Large-14WheelsFlatbedTrailer.rfa](https://forum.dynamobim.com/uploads/short-url/w2ARm8CtQu7hyQPgwoTt7ZhdAKT.rfa) (3.5 MB) > This is the result that I get for this family example: > ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/9/9/999a8bb172a7b3fc1c3da69d956fc3a1f115de91.png) ---

Probably there are also a lot of nodes that can do that. My first with node from BimorphNodes v.3.0.3. ![youarewelcome](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/7/2/72db21d6de5534dd5be4b33f53c2bad7aa16487a.jpeg) ---

Thanks Nenad Kovacevic, I don’t want to get only solids, that example was like ideal solid made model, quite rare. Usually you find many combinations of geometry. I would like to get any geometry from a project file and from a family type stored on a project revit family library, but not placed instance ---

Perhaps post an example containing the less rare content? Geometry failing in masse like this is actually extremely rare, and I have found often has to do with geometries which throw one or more suppressed warnings under the hood in Revit (slowing down models but allowing things to work - check your journal for more info). ---

Oh think I see what the issue is… looks like you may be trying to get the geometry from an inactive family symbol - that is the project hasn’t computed what is in it just yet. If this is the case, there may be some options, or there may not. How are you loading the family into the file? Let me think on this today and see if I can come up with some things to try. ---

Yeah it looks like the inactive load may be at play. Been awhile since I have run into this though so I may be off base. Let me poke around for a bit next week, but if this pans out nothing would produce that geometry without first generating the geometry in the document. You can’t fetch what doesn’t yet exist. As a test, try opening the model with audit before attempting to fetch the geometry - this might put the geometry in place by performing the full regen on the DB and the missing geometry lines could be resolved that way. ---
