Level Surface Mesh
This add-in creates meshes from the level surfaces (also called isosurfaces) of a user-supplied mathematical function. A live preview is shown in Autodesk® Fusion 360™ as the parameters are updated, and when the command is executed, the mesh object is created in the current document--no need to save it externally and import it yourself, as you have to do with external mesh-generation apps.
The user provides the bounds of the rectangular region in which the mesh will be rendered, as well as a function of x, y, and z. The mesh is created from the level surface f(x,y,z)=0.
