| operation

| shape |

MarbleCLAY is a polygonal modeler. You can create polygons one by one from scratch, but first you can do the following steps to create primitives Experience the easy vertex selection function that is a feature of MarbleCLAY.

| Placement

As an example, I will explain how to make a sphere.
1. First, open a suitable document with File->New(Ctrl+N) or File->Open...(Ctrl+O).
2.If you opened a new document with File->New(Ctrl+N), open Mesh Modeling->Make primitive object and execute Sphere....
3. If you opened an existing document with File->Open...(Ctrl+O), select which object to add the primitive to.
3-1.Open Object window and select the parent object (or submesh).
3-2. Select Root if you want to generate a primitive as a separate object.
3-3.Open Mesh Modeling->Make primitive object and execute Sphere....

| HowToSelect |

Describes how to select objects. Select all or part of the object created by Placement using one of the methods below, then proceed to "Move/Rotate/Scale".

| selection

Select selection and select the type of element you want to select with Select Filter.
Then when you move the mouse cursor over the element you want to select, the element will be display and a mouse click will select that element.
It is often used when fine-tuning and arranging shapes.

| selection

1. Select selection and select the type of element you want to select with Select Filter.
Next, drag the mouse cursor to draw a rectangle and release the mouse button to display the menu. You can choose to select all elements within the rectangle or select according to the filter settings.
2.In selection mode, if you start dragging the mouse from a place where the element does not exist, you can select the same as 1.
Also, option allows you to choose between ``select by menu'', ``always select all'', and ``always select with filter''.

| click

This is the easiest way to select an object, which is possible in modes such as Move(1)
Scale (9), and 2D Rotate(8).
1. Double-click the vertex or face of the object to select all connected parts.
2. If you double click on an edge, the edges that are contiguous to that edge will be selected
(see *Special-delete(BkSp))

| edge

| polygon

See click

| selection

1. Press the left button on the edge of the polygon you want to select.
2.Press the left button and click the right button to select a belt of polygons.

| continuous

1. Select selection and select the type of element you want to select with Select Filter.
2.When you start dragging the mouse over an unselected element, you can select the elements connected to that element continuously.

| All

Edit->Select all(Ctrl+A)Menu
can be used to select all current objects.

| edge

Edit->%EditSelDopel%Menu
If there are multiple edges with the same set of vertices, select one edge.
When outputting to a file format that does not allow multiple edges, such as RDS output, first After selecting the multiple edges with this command, do an Delete(Del) to remove the multiple edges.
(In many cases, the shape changes slightly, so manual correction is required)

| edge

Edit->Select single edgesMenu
Select a single edge with no faces.

| shared

Edit->Select common edge between two trianglesMenu
Select edges that share two triangular faces. However, two triangular faces are selected here. It is only the thing that the combined shape becomes a shape close to a square.
After running this command, Special-delete(BkSp) will delete an object consisting of many triangular faces. It can be an object consisting of quadrilateral faces.
However, since it uses a simple algorithm, it is not possible to select an object that looks like a square surface. There are many things.

| color

Select &actSelectSameMaterial Edit->Select continuous faces with same materialMenu
Selects faces that have the same color attributes as the currently selected faces and are contiguous.

| by

Clicking the icon (the cone surrounded by a red frame) to the right of the polymesh name in the object window selects all the faces that make up that polymesh.

| Move/Rotate/Scale |

| object

To move an object or vertex, you must first select the part to be moved.
See HowToSelect to select the object you want to move.

| move

Select Move(1) and drag selected objects or vertices to move them in a direction parallel to the workplane. (See WorkPlanes 3D Perspective View))
Even with Move(1) selected, you can select and move other vertices.

| using

If you select Move(1) and do View->%ViewMani%
Manipulator will appear in the selection.
By dragging the arrows for each axis of this Manipulator, you can move the selected part along each axis (regardless of the state of the workplane).

| Rotate

Selecting 2D Rotate(8) displays roll control points around the selected element. Drag this control point to rotate the selection in a direction parallel to the workplane.
Also, by Shift+clicking an appropriate vertex, you can set that vertex as the center point of rotation.
Even if 2D Rotate(8) is selected, you can select another vertex and rotate it. Furthermore, you can also move the selected element by dragging the selected element.

| rotation

Select 2D Rotate(8) and do View->%ViewMani%
Manipulator will appear in the selection.
By dragging the arrows for each axis of this Manipulator, you can rotate the selection around each axis (regardless of the state of the workplane).

| scale

Selecting Scale (9) displays scaling control points around the selected element. By dragging the point at the vertex of the cube among these control points, you can scale the selected elements in the direction parallel to the workplane.
Dragging the control point at the center of the cube face scales the selected elements in the direction perpendicular to the cube face (regardless of the workplane setting), and holding down the Ctrl key while dragging will do the opposite. You can scale around the control point on the side face.
Also, by Shift+clicking an appropriate vertex, you can set that vertex as the center point for scaling.
Even if Scale (9) is selected, you can select other vertices and scale them. Furthermore, you can also move the selected element by dragging the selected element.

| Polygon generation with mouse |

Basically, we use face/UV weld(3) to create faces.
With face/UV weld(3) selected, from Create a single face to an You can work smoothly without being conscious of mode switching. Is possible.
Because there are many elements that are done automatically, depending on the user There is a part that I am taking care of too much, Restricting functions by setting tool options takes time and effort Instead, configure it to do exactly what the user intended It is also possible.

| Create a single face

To create a single face:
1. Select face/UV weld(3)
2. Click the left button anywhere
3.Click two points in succession
4. Click again at the first clicked point

| faces

To create a face using existing faces and edges,
1. Select face/UV weld(3)
2. Select any vertex and click
3.Continue to click another place
4. A face is automatically drawn on the square or triangular part.
However, "user-explicit" face generation in tool options If you are in mode, the surface is not automatically stretched. always You will use the Create a single face method.

| 2

Only v2 version, but strip input can create faces continuously.
1. Select face/UV weld(3)
2.Click while holding down the Shift key to draw a U-shape.
3.A square face is attached to the U-shaped part.
4.Click while holding down the Ctrl key to draw a Λ character.
5. A triangular face is put on the Λ part.
In v2alpha4, getting used to making the intended surface well is necessary.

| a

When using face/UV weld(3), it is possible to turn quadrilaterals into triangular faces.
1. Select any vertex of the face you want to divide and click
2. Select the other vertex on the diagonal line of the face and click
A new edge connecting the two clicked points is created, and the original face is Divided into triangles.
See also Triangulate Polygon.

| an

You can use face/UV weld(3) and Polyline(5) to split the quads.
1. Click on any edge of the face you want to split
2. A vertex at the clicked position is created and the face is automatically divided into two.
3. At this time, the newly created edges are called semi-definite edges.
As it is, it will be divided into one square and one triangle, You can divide it into two quadrilaterals by performing the following operations in succession.
4. Click on the edge opposite the edge you just split
5. Then a new edge connecting the two clicked points will be created, and the original rectangle will be It will be divided into two rectangles.
6. The semi-definite edges have now been removed.
7. By continuing to divide the adjacent surface, it is possible to divide a continuous surface.
See also Cut(6)
Add vertex(4).

| when

Since the creation of faces is automatically performed on the parts where quadrilaterals and triangles are The surface may be stretched in an unintended place.
For example, a newly created edge can compose a triangle and a quadrilateral at the same time. You might. At this time, MarbleCLAY cannot determine which side the user wants to put the surface on. Therefore, I choose the appropriate one and paste the surface.
To avoid this use:
1. Specify to generate either triangular or quadrangular faces.
Uncheck the one you don't want to create in the tool option check box, or When specifying vertices with face/UV weld(3), click while pressing Ctrl (triangle only) or Shift (rectangle only).
2. Set surface generation to "user specified" mode
Make your selection in the radio group of tool options.

| 2

MarbleCLAY is limited to 2 faces per edge. It is not possible to put a face on a place that constitutes three or more faces.
However, there is either a bug or the imported shape contains such a shape In such a case, an edge that apparently consists of three or more faces may be created. I have. In reality, there are no edges that form three or more faces, There are multiple edges at the same position, but it is inconvenient if it is left as it is (RDS format Export cannot be performed normally, the shape becomes unexpected when curved, etc.), so the following A procedure must remove such edges (called multiple edges).
1.Edit/perform multiple edge selection
2. Run Edit/Delete
3. Due to the deletion, the necessary aspects may also be lost. If so, fix it manually is needed.

| guidelines

How to paste a surface along a line created by Polyline(5) or a
Even though it is a guideline, it is the same as a normal edge, so use methods such as faces It is possible to create faces, but the number of vertices of the guideline is limited to the shape you want to create. It can be difficult to work with too many or too few vertices Therefore, do the following:
Some overlap with the description in a
1. Select all guidelines and give them a new name. (only guidelines in the object) If it doesn't exist, leave it as is)
2. In the object window, click the lock icon next to the name you gave the guideline
to lock
With this, operations such as moving and dividing will not be performed on the guideline, and further vertices will be Since it will not be displayed, it will be easier to perform surface creation operations. Specifically,

| a |

Instead of suddenly creating a polygon, first create a line that serves as a guide, then create a polygon along that guide. There is also a way to create one.

| Polyline

If you know the shape of the polygon you want to create to some extent, use Polyline(5) to create a guideline with the same degree of roughness as the final polygon you want to create. It would be nice to write

| the

If you have a tablet, or don't need guidelines as rough as the final polygons you want to make, Freehand polyline is a quick way to You can write guidelines.

| guideline

For guides created with Freehand polyline, the guideline becomes part of the polygon during the polygon creation process, which can be very annoying. Because there are many, it is recommended to lock when the guideline is made.
Clicking the padlock to the right of the guideline in Object window locks the guideline.
guidelines also has documentation on locking.
TODO: Insert figure here

| the |

| generation

Similar to face/UV weld(3), this is a function for creating faces, but this uses existing faces to create faces.
The color of the face will be inherited from the existing face.
1. Select Extrude(7)
2. In the Tool Options window, select "Parallel Extrude, Bevel Extrude, Move Extrude choose one of the
3. Select the face you want to extrude (see %AnotherSel%)
4. Place the cursor over the selected part, and press the
button while pressing the left mouse button. 4-1.Drag to the right to extrude the surface in the direction of the surface (parallel extrusion, bevel extrusion)
4-2.Drag to the left to extrude the face toward the back of the face (parallel extrusion, bevel extrusion)
4-2. Drag to extrude the face in that direction (move extrusion)

| face

Extrude edges in any direction.
However, the extrusion format specification is ignored and "move extrusion" is performed.
1. Select Extrude(7)
2. Confirm that "Extrude edges and vertices" is checked in the tool option window
3. Select the edge you want to extrude (see %AnotherSel%)
4. Place the cursor over the selected part, and from there hold down the left mouse button and Drag to extrude faces in that direction

| vertices

Used with face. If you want to create a face in the shape shown below, face You won't get the faces you want, but this kind of shape is very common when you use face to create faces.
In such a case, you can extend the surface by performing the following operation.
1. Select Extrude(7) (optional if already selected)
2. Confirm that "Extrude edges and vertices" is checked in the tool option window
3. As shown in the figure, drag the vertex of the part where you want to extend the surface diagonally and release the mouse button on the arbitrary place or on the other vertex
(Cannot extrude multiple vertices at once)

| Synthesis |

| vertices

In face/UV weld(3) mode, drag any vertex over another vertex and drop it to weld the two vertices together.

| Merge

You can weld vertices by selecting multiple vertices and running Mesh Modeling->Weld...(Ctrl+W).
At this time, in the dialog, force all vertices to be welded to one vertex (%ForceWeld%) or You can choose to weld only vertices that are close together.

| Faces

Select the faces you want to combine and the edges that share the faces, and execute Special-delete(BkSp) twice to combine the faces into a single quadrangular face. can be converted.
Synthesizable conditions are
(+) Triangular face + Triangular face
(+) Square face + Square face
is the case.

| value |

By entering a number in the position field of Property window It is possible to move the currently selected element.
Absolute value specification and relative value specification are possible for the input method.
By entering a number in the size field of Property window It is possible to enlarge or reduce the currently selected element.
Absolute value specification and magnification specification are possible for the input method.
If you want to do so, click the object once and click the object's new Please reacquire the position and size.
Calculator can be used to aid numeric entry.

| Nudge |

By pressing Alt + cursor key, it is possible to move the selected element slightly.
If you press the cursor while the 3-view drawing is active, it will move slightly in the direction you pressed the cursor.
When the perspective view is active, Alt+left cursor is -Y direction, Alt+right cursor is Y direction.
ALT+up cursor is -X direction, Alt+down cursor is X direction. Hold Alt+Ctrl and move the up cursor in the Z direction and the down cursor in the -Z direction.
The movement distance can be changed in the environment settings, and by pressing Alt + cursor key while pressing the space key, the set movement distance will be x10.
From Beta5.1, the specification was changed to press the Alt key at the same time. However, if you change the environment settings, you can perform nudge operations with only the cursor keys as before.
Next, Manipulator
