Good morning. I have a problem… please I would like your help… I’m trying to get the intersection between the geometries… I just want to get the intersection as a result… but it doesn’t work for me… ! What am I doing wrong… thank you very much for your help ![INTERSECCIONES ENTRE GEOMETRIAS](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/1/3/130220124d6c7c9b9fc962dc86cd655af07f7777.jpeg) [Geometry intersec.rvt](https://forum.dynamobim.com/uploads/short-url/dgPmwQpkkKLSRlgecterkexSSBW.rvt) (6.2 MB) [GEOMETRY INTERSECT.dyn](https://forum.dynamobim.com/uploads/short-url/lOl08vXA0i5BNaeImmHu5ID9tWF.dyn) (8.7 KB) ---

Hello @AM3D.BIM.STUDIO probably something could work in that case… ![Capture.PNG](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/6/d/6dec5fa5966091bbc6c82426eab7e8e5f7d95365.jpeg) or something ![Capture](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/b/e/beb0e9fee2f2659c83f45db32d5d83eb02b1f32a.png) ---

Hi, I believe this is what you need 🙂 You only had to get rid of intersections, represented by an element, intersecting itself, which is the the element’s own geometry ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/5/a/5af69cff5a36edb28ca68b861f5a4d35c4097482.png) Here’s your updated graph: [GEOMETRY INTERSECT.dyn](https://forum.dynamobim.com/uploads/short-url/tii3Kycq3RsZtbReemWj16KXP1v.dyn) (22.6 KB) ---

Hi @danail.momchilov nice one…but think you still will need a prune or something here,ps i only count the solids … ![Capture.PNG](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/e/3/e3daeff5e4a3e18ba8e813afe4f6d020bd7d4f9c.jpeg) ---

Hi, yes you are right, might be a good idea cleaning anything other than a solid in the end (or along the way) 🙂 ---

yeah agree 😉 i would try do it in the beginning so we dont have nulls…yeps many ways here and thats nice 😉 ![Capture.PNG](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/7/c/7c1bc17e2a6fb8d6cd8762d83c316e28c4cad215.jpeg) ---

Yeap! In the beginning might be actually even better, as you don’t get these warnings as in my graph 😉 PS: I adore new Dynamo’s interface… we are still behind on upgrading our models, so I am still stuck with 2.6 (2021) ☹ anyway, coming soon ---

[Kesişmeler.dyn](https://forum.dynamobim.com/uploads/short-url/dDDqTVR831xAaWOzwPM5f2xSpYG.dyn) (57.3 KB) I actually want to subtract the areas of these intersecting surfaces from their surfaces. Can you help with this? Thank you in advance. I am grateful. > [@Surface square meters of floors](https://forum.dynamobim.com/t/surface-square-meters-of-floors/85419): > > I print the surface square meters of the tiles. I just want to write the sum of its side and bottom surfaces. but I can’t find the elements correctly. The lists are mixed. For this reason, I always write the wrong values to the wrong elements. Got a friend who can help? I’m grateful already. ---

I’m trying to do what you’re doing this hasn’t happened to your chain I tried to do the same. i made the file? If you look at it it seems like enough for me.
