This solid must be a closed extrusion or polysurface.

A polysurface consists of two or more surfaces joined together.

The STL format requires a valid closed polysurface.

Meshes for each surface in a polysurface do not necessary meet to form a watertight mesh.

Creates a separate developable surface or polysurface from each pair of curves.

The compact second surface formation 13 (FIG. 1) is shown in FIG. 5 by way of example.

You have one solid closed polysurface that is fully intersected by a single surface.

If the polysurface fully encloses a volume, it is also a solid.

However, a polysurface may be “bad” because it contains only one bad surface.

Now window select them all and use Join to make them into a polysurface again, and see what happens to the surface directions.

This is because it lets you extract only the selected surfaces from the polysurface, and so there is not as much joining work to do afterwards.

For RP purposes it is very important that the Rhino surface model be a closed volume (closed valid surface or polysurface).

Now window select them all and use Join to make them into a 4 sided polysurface again and use Dir again to see what happened to the surface directions.

It does so by creating one NURBS surface for EVERY mesh face in the original object and joining the result into a polysurface (assuming the original mesh has more than one face).

In another embodiment, a compact second surface formation 13 has the shape of a quadrilateral (square, rectangle, rhombus) or a different shape bounded in any desired way.

In this example, the linear surface formation 12 contains the information “Start/010 . . . 11”.

If the entire surface formation 13 is illuminated at once, a reading machine having three diffraction planes 100 (FIG. 3) and having five pairs of the photodetectors 25 (FIG. 3), 26 (FIG. 3) recognizes any given state out of 4 5 =1024 states which is defined by the choice of substructures.

This ensures, that the resulting face model can be used afterwards for solid operations or NC programming without any rework (fig. 5/6).

RENDER MESH ONLY Use the MESH command to mesh the model and then HIDE the NURBs polysurface.

The quickest way I find to check an object for whether it is a solid (closed polysurface) or not, is to click on the details button in Properties, which I leave open and docked on the right side of the screen, with the Layers panel docked right beneath it.

If the curve is a polycurve of lines and arcs, the result is a polysurface with joined surfaces created from the polycurve segments.

Notes When you are extracting a surface from the polysurface the ExtractSrf command can save you a lot of time (as opposed to Explode).

So when you have an open set of joined surfaces (an open polysurface), it will still have one uniform front/back and not be a patchwork quilt of surfaces facing in different directions.

This ensures that the resulting face model can be used afterwards for solid operations or NC programming without any rework (Figure 5 and 6).

Now window select them all and use Join to make them into a polysurface again, and see what happens to the surface directions.
