Object Panel

The following operations can be executed in the menu displayed by clicking the right button.

Select vertices/faces	It selects all vertices and faces in the current object.
Unselect vertices/faces	It unselects all vertices and faces in the current object.
[Patch], [Mirroring] and [Smoothing] are same as them in the [Object Property].

New	It creates a new object. When you click the button pressing the Ctrl key, a new object is inserted after the current selected object.
Clone	It creates a cloned object of the current object. When you click the button pressing the Ctrl key, new objects are inserted after the current selected object. Position It changes the position of created clone objects. Relative In [Global], clone objects are moved to X, Y, Z along Global axis. In [Local], they are moved along the Local axis. Create at center Clone objects are created at the center. Create symmetry Clone objects are created at the position symmetrical with respect to the Y axis. Rotate It copies objects and rotates them. Rotation axis It is the direction of rotation. Rotation angle It is the angle, an amount of rotation. If you set [Number] to two or more, each clone object rotates by an amount obtained by dividing the rotation angle by the number. Rotation center It is the center of rotating objects.
Delete	It deletes the selected objects.
Property	It sets up the objects. [Detail]
<  >	It moves the hierarchy level of the object by one upward or downward.
Misc	It sets up the visibility and the editability. Show selected only It only shows the current object and does not show other objects. Show all It shows all the objects. Lock non-selected It makes only the current object to be edited and locks others to be edited. Unlock all It makes all objects to be able to be edited. Merge all It merges all objects into one. Merge all visible It merges the objects with display status into a single object. Objects which are not shown are untouched. Merge selected It merges the selected object in the list into a single object. Objects which are not shown are untouched. Show color It selects whether to show the color of each object on the list in the object panel. Show folder It selects whether to show hierarchical child objects. All objects are shown in the same line in spite of a parent-child relationship when you select OFF. Edit also children It selects whether the change of the status of visibility or locking is synchronized to child objects. Set as default It registers parameters in the selected object as default values. The parameters for a default object can be restored to the initial state by button.

And you can change the order of objects or merge them with other objects.

	Objects are shown when the eye mark in ON. When you click the object dragging the Alt key, only that or all objects are shown.
	Objects are fixed and cannot be edited when the key mark in ON. When you click the object pressing the Alt key, only that object or all objects become to be able to be edited.
	It selects whether to fold the display of children-objects in the object panel. Child-objects are all shown when it is looking down and they are hidden when it is looking right. ("obj4" is hidden under "obj3" in the left picture.)
	It indicates the object has no child. The down/right direction affects nothing.

Object Property

Object information can be confirmed. In addition, you can be set for the following items.

• Object's name
• Patch
• Mirroring
• Lathe
• Smoothing

Object's name

It sets up the name, color, visibility, and the editablity.

The color selected in [Configuration] is applied when a cross mark is put on the colored section and the color selected here is applied when a cross mark is not shown. If you click the right side when a cross mark is not shown, it is put again.

Patch

It selects how to control faces of an object.

Flat

It shows normal surfaces. Triangles, quadrangles and polygons can be displayed as surfaces.

Spline Type 1

Basically, patch is applied to only quadrangles. It is applied to only triangles whose three sides are surrounded by quadrangles.
The edge of the unclosed patch is located away from vertices and lines. It becomes exactly the same as "Patch type 2" for a complete closed patch.

Spline Type 2

Basically, patch is applied to only quadrangles. It is applied to only triangles whose three sides are surrounded by quadrangles.
The edge of the unclosed patch is located near vertices and lines. It becomes exactly the same as "Patch type 1" for a complete closed patch.

Catmull-Clark

Triangles, quadrangles and polygons can be subdivided by Catmull-Clark.
When the [Reserve triangles] is ON, triangles in the original object will be subdivided into multiple triangles. Subdividing with reversing triangles can make a smooth patch around the border between a triangle and a quadrangle.

A Catmull-Clark subdivision makes different patches from Patch type 1 or 2. But it may give the same shape in other software because a Catmull-Clark subdivision has compatibility with many other software that supports a Catmull-Clark subdivision.
(Caution: Please confirm compatibility with an other software because some software make different patches from Metasequoia, and creased edges or open edges also make different patches.)

OpenSubdiv

Triangles, quadrangles and polygons can be subdivided by OpenSubdiv.
OpenSubdiv produces almost same result as Catmull-Clark in case that no weight is assigned. OpenSubdiv can obtain the more detailed shapes than Catmull-Clark by setting weights.

You can set the following options to OpenSubdiv.

• Limit surface - When you increase the number of [Segment], OpenSubdiv curved surface shrink. But if you check this option, curved surface is divided always in the shrunken size.

Limit surface OFF
Segment: 2	Segment: 16

Limit surface ON
Segment: 2	Segment: 16

• Smooth triangles - When it is checked, the shape around triangles becomes more round.
• Mesh interp. - It is to specify an interpolation method around opening edges.

Edge only	Edge & corner

• UV interp. - It is to specify an interpolation method around opening UV edges.
  
  The left figure is an object applied to OpenSubdiv, and the right figure is the UV development view of the object.
  When such UV developed view has a break, it is possible to interpolate the UV linearly.
  • None - Interpolation is not. UV boundary is a curve similar to the surface boundary.
  
  • Corners only - Only corner of the UV boundaries are interpolated.
  
  • Corners Plus1 - In addition to [Corners only], the intersection of three or more UV borders are interpolated.
  
  • Corners Plus2 - In addition to [Corners Plus1], concave cuts are interpolated.
  
  • Boundaries - UV corner and border all are interpolated.
  
  • All - All of UV, including the inside of the development view are interpolated.
  

The surfaces in an object assigned a patch can be converted to faces by [Menu > Object > Freeze].

Mirroring

It selects the mirror shown in real time. You only need one side of the data of wire structure.

• In [Separated], the copied face is created on the other side and each face is treated individually.
• In [Joined], in addition to the face created on the other side, the face which can connect to the original face is created. When you put a limit on the joining distance, the face connecting both sides of the faces is not 0created if the faces are located in farther than the selected distance from the symmetrical boundary (XZ plane, when you make the mirror in the direction of X axis, for example).

Original	Separated mirroring	Jointed mirroring

Lathe

It selects lathe displayed in real time. You can make the rotated form of the line in the object around the selected axis.

Normal	Lathe

Smoothing

It selects whether to make faces smooth. When [Smooth shading] in the menu of the [Disp] button in the view header is checked, objects which are selected on smoothing are displayed smoothly.

Angle

It specifies the angle to apply smooth shading.

Smoothing for a 12-points polygon.
30.5 degree	29.5 degree

Calculation method

It specifies the calculation method of smooth shading.
In [Angle], smooth shading is applied according to the angle of faces, in [Angle and area] it is applied according to the angle and the area ratio of faces.
