| surface

MarbleCLAY is a polygonal modeler, but allows surface modeling using two different formats: SplineMesh1(F4) and SplineMesh2.
Since the surfaces used in these curved surface models are always automatically generated from polygon models, modeling with a high degree of freedom, which is a feature of polygon modeling. You can maintain the feeling of operation.
However, modeling operations are always done on polygons, which has the following drawbacks:
1. It is not possible to add vertices on the surface or make holes in the surface without destroying the outline of the surface. (SplineMesh2 may be resolved to some extent in future versions)
2.Since curved surfaces are handled indirectly through polygons, it is difficult to intuitively grasp the editing results. It lacks the sense of touching the model directly. (However, I think it is possible to get used to this.)

| generation

The surface generation method is very simple.
1. First create a suitable object by referring to operation.
2. Select the object you want to curve in Object window.
3. Doing Mirror/Curve->SplineMesh1(F4) or Mirror/Curve->SplineMesh2 will curve the selected object.

| surface

If you Export a curved surface model created with MarbleCLAY for use in another application, only the polygons before surface conversion will be exported.
If the application has the ability to generate surfaces from polygons, this is possible, but if not, the surface must be polygonized before Export using the following procedure.
1. Select the object you want to polygon with Object window.
2. Run Mirror/Curve->Convert SplineMesh to Polygon(Ctrl+F4)
3. Enter the level of polygonization. (Example: Entering 4 divides one face into 4x4=16 polygons.)
4. A polygonal object will be generated with the name + "(Freeze)", so select this and perform Export.

| tuning

(+) When Sharpen edge(S) is used, the edge of the curved surface can be set. (Run Smooth edge(Shift+S) to return to original state)
(+) You can sharpen or smooth the selected vertices by executing Sharpen vertex(Maximize weight)(Alt+S)
Smooth vertex(Reset weight)(Shift+Alt+S), etc.
(+) In Move(1) mode, right-drag the vertex whose weight you want to change to the right to increase the weight, and right-drag to the left to decrease the weight.
