Hi all, I’ve had a look around but not been able to locate a answer to this with good old Google and Forum Searches. Basically I am using Genius Loci’s “3DView by BoundingBox” to generate 3D Views using the Room’s geometry. I have this working so my question is this : Is there a way for me to add some form of offset to the bounding box so it goes beyond the size of the room? Thanks! ---

hi, it seems to me that Mr. ChuongMEP with his [openMEP](https://forum.dynamobim.com/t/openmep-package-feedback-thread/) package presented nodes that do this > [@OpenMEP Package Feedback Thread](https://forum.dynamobim.com/t/openmep-package-feedback-thread/86350/34): > > New version in [2.0.23.2331336](https://github.com/chuongmep/OpenMEP/releases/latest) released kissing_heart What is news : Add more power full to work with [Bounding Box](https://chuongmep.github.io/OpenMEP/api/OpenMEPSandbox.Geometry.Abstract.BoundingBox.html) Boundingbox.IsSimilar Boundingbox.Scale Boundingbox.Divide Boundingbox.Visualize Boundingbox.Area Boundingbox.Volume Boundingbox.ByBoundingBoxs Boundingbox.Corners Boundingbox.Center Demo Preview : [explorer\_DAjsKIWxYK] [BoundingBox.ByBoundingBoxs] See more detail document : [Class BoundingBox | Open MEP](https://chuongmep.github.io/OpenMEP/api/OpenMEPSandbox.Geometry.Abstract.BoundingBox.html) cordially christian.stan ---

If you want a method which doesnt require any external packages (except for colouring my geometry) the you could do this: ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/8/5/85945960200233ce71ec50be801a27ed9ed774e3.png) Extract the corners from the origin bounding box (red), create a vector using them, offset by your desired amount then recreate the new bounding box (green) ---

hi @christian.stan & @haganjake2, _Changed accounts as I have changed jobs (my login in automated to my new Autodesk ID… so will marked resolved when I get home this evening)_ Thank you both for your responses! I have got some time for more Dynamo at work and these worked great. I think the part I was not understanding was the part of using the room bounding geometry along with its reversed geometry! ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/5/5/558b69185725b3ea42d27dec7b9fa2ef3f2635c0.png) Now works perfectly, many thanks! 🙂 ---

hi @haganjake2 & @christian.stan , I have run more tests on this script and this script only works where there is only one set of Room geometry data, which makes sense looking back at it. I did manage to resolve this by creating the nodes within the blue group, into a new custom node. That then allowed the data to flow through as a list and retain its order and structure. (just in case someone else tries to recreate this!) Thanks again ---

Hi I’m trying to creat 3DViews with the geniusloci Node, but for me it seems to always give out null. Im feeding it a boundingbox from element.boundingbox and a string with normal letters a-z, any suggestions why it is not working for me?
