Hi all I am trying to create bounding box around the elements with 1mm offset. The pictures are shown as below. ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/0/4/041a69c5356616d6de73bee14d72cf5545fa73fe.png) I am trying with below code but is somewhat different. I have extract the b and h values of column elements and I was trying to add 1mm to every corner nodes. But it the rotation of bounding box is the main Isuue. Please let me know how do I proceed ? ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/a/0/a0b1d52d2655c7ab515cee4970e44afc0bb8a9e2.png) Thanks in advance. ---

You cant rotate boundingbox there are x y aligned but saw the other day @GavinNicholls had a work around…Think it was with cuboid ---

Hi @sovitek I want to know how to rotate solids or bounding box ? Because as we have nodes for elements but I want to rotate my solids or boxes. Please let me know ---

Ah, this old chestnut again… Yes I rotate the geometry of the family instance by its rotation angle, bound that, then rotate the cuboid of that bounding box back the other way. As far as I know element aligned bounding boxes aren’t (easily) a thing in Dynamo. I believe you can use Revit API to assess Revit bounding boxes at a rotation if you reference a rotated coordinate system based on previous answers on these threads. As for the 1mm offset, you’ll need to get the min/max bounding box points and move them to form a new one by shifting them 1mm in the X/Y positive (max point) and negative directions (min point). ---

In your case why not just intersect with a plane and get the perimeter curves ---

Something like this ![intersect](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/4/9/49b97a952b692d0887eb370099e4f02f54f2913a.png) This is slightly processive intense so if you happen to have a few thousands i would simply recreate the outer boudaries with the parameters ---

Thanks alot @GavinNicholls @sovitek I got the solution. As you motioned I extracted the max and min points and the gave diagonal offset of 1mm to both the points and then I recreated cuboid with min and max points. The script follows as below ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/1/4/148e8240564f845d47a587e271fb2a5960834e3a.jpeg) Thanks for the suggestions. ---

Hi @Daniel_Hurtubise Thanks for your response. I’ll definitely give a try.
