Creating a Scalar Density Map

Hello, I’m very new to the Grasshopper3D. I’ve used the Topopt plug-in in order to conduct a topology optimization in 2D. I’ve obtained the density values but couldn’t figure out how to know the corresponding location for each grid in x,y,z plane with its density values. I need to get the points in a format of x,y,z,s where s corresponds to the density value. Then, export the data into Excel to create a .csv file. Sorry for my English. (7.3 KB)
