By using the MinPoint and MaxPoint of this bounding box, we can find the top and bottom of the mesh, and use those in our code. To figure out the top and bottom of the mesh, we first grab the list of triangles in the mesh with Mesh.Triangles, then create a Polysurface container to hold them all, and finally compute the bounding box around the Polysurface (which is exactly around the mesh). " which goes up to but not past "end." In this case, we need to start at one layer height above the bed, then go up one layer height at a time, but not past the top of the mesh. This feature has the format "", and makes the list of numbers "start, start + step, start + 2*step. For the Z coordinate, we use Dynamo's built-in "range" feature. The X and Y coordinates don't matter, so we can just set both of them to zero. This node requires XYZ coordinates to construct a point. We create a Point.Båoordinates node for the origins of our planes. Since all of our planes are parallel to the build platform, we can just use the Z axis vector for each plane's normal. For this node, we need an "origin" point for each plane to pass through, as well as a "normal" vector perpendicular to the plane. To build the plane for each layer, we will use the Plane.ByOriginNormal node. If you select an STL file in the File Path node, you should see your design appear in the viewer. For this, we make a File Path node and connect it to a Mesh.ImportFile node. We also have to import our file to slice. However, you can get much fancier with sliders under the Core > Input menu. In Dynamo, the easiest way to do this is to double-click and create a code block with all the settings.
