Hi, I want to make a contour plot of my 3D Mesh. The 3D mesh is not a surface. But a solid object. I have already extract the faces of the object. But still cannot make a contour. Anyone know how to do that? Also, if I can make the contour, can I extract the laterl position of these equal height lines? I want to do some calculation on these equal height lines, such as calculating the lateral distance between two equal height lines. Below are the pictures of my 3D mesh. The first one is just a solid scatter of my object. The second is the pdeplot. The third is the nodes on the face 1, and face 7.
NOTE: I only want the equal hight line of the part that can be hitted by a sunlight came from the top along the z axis.
