Im trying to implement a method which can easily show the footprint of a mass. The revit mass dynamically updates gross floor area, but not footprint, so i attempted at a graph that would do so. [image] [image] The graph takes all surfaces from the geometry, filters surfaces that have a normal ve…

Hi @Tchunoo_Rhee_Kahng Here is one of the possible way to get mass bottom surface. [image]

@Tchunoo_Rhee_Kahng Ensure there is a level at the base of the mass and a corresponding Mass Floor, you can then do something like this… [image] Also, the nodes in your screen shots abbove aren’t clear. zoom in until the text in the nodes is visible before you capture the screen in Dynamo. The e…

@Vikram_Subbaiah @Kulkul thanks for the response guys!! I believe i have not articulated my question. I want to figure out the Building Coverage of a mass with a “Footprint(touching GL)” is not equal to the Projected Boundary in Site Plan. So i just want to find the “Site Coverage” of a Mass. [i…

@Tchunoo_Kahng My above suggestion should work. Assuming Level 1 is footprint level, extract the mass Floor Area of Level 1 In the example below the base of each block is 100sqm, the resulting Mass Floor Area parameter reads 200sqm [image]

Hello, this outer boundary method could probably help: Get an outer boundary of multiple polygons (Room Boundaries)
