The Modelling tool allows for plotting multiple interconnecting points in a 3D environment which are forming custom surfaces and shapes using the Active Block to determine which block is being used for them.
Furthermore the surface options feature the ability to link multiple points together, forming a row. Multiple rows can be added and will be assigned an index. Points within rows are only able to connect to points of adjacent rows. These properties will form a lofted surface which will differ depending on which algorithm is being used to calculate the mesh connecting rows and points with each other.
