Use-type Modeling

1. Create object:

Only when renderable is checked can the shape be rendered as a visible surface. Type is always modified or used as a secondary object to define a visible 3D surface. It can also be used to define the motion path.

1. Terms for understanding splines:

   Jiyu	Overview	Genus
   Node	Point at any end of the spline. Types include: corner, smooth, and bezeiser.	A node is a type object.
   Tangent handle	The tangent handle is displayed after the node type is set to bezr.	The tangent handle is a node attribute.
   Line Segment	A Spline between two points is a line segment.	Is the type of secondary object.
   Steps	Number of segments that are divided into small segments to express a curve.	Two properties of the step control model: the smoothness of the curve and the number of faces generated by the model.
   Spline	A set of mutually connected line segments.	Is the type of secondary object.
   Type	A set of spline curves of a defined object.	Type constraints on the type and number of splines vary with the type purpose.
   Path	Descriptive terms. A path usually refers to a shape that contains a single spline.	The path in 3DS MAX refers to the shape of a single spline.

   Select the front view and issue the views/background image command.

2. Use a drawing tool to depict an image:
3. Create text:

   (1) The text parameters, spelling, and font can be changed. You can also use an editing modifier for the text type to deform the text like a deformed ry.

   (2) Some poor fonts may contain non-closed text types. The top and bottom surfaces cannot be formed when Extrude and bevel are used for thickening. Solution: A. edit a node. B. After the stack is collapsed into an editable mesh, use the CAP holes edit modifier to solve the problem.

   (3) When you use text lofting, it is very easy to cause resource crisis in your system. The feasible method is to optimize it and collapse the stack into an editable mesh, this reduces the machine memory overload caused by rendering text objects.

4. Create a section: the section type is unique. It is not a type, but its purpose is to create a section.
5. Create multiple spline curves in the same shape (such a shape is called a compound shape): method 3 A, select a shape, and then clear the start new shape check box. Then add a new type to it. B. Apply an edit spline edit modifier to the type, and then use attach to add other types to the selected type. C. Collapsed type, and attach or attach multiple is used.
6. Comprehension interpolation:

(1) Step number (Steps): When the model is used to create a 3D ry, the step number parameter can accurately control the number of sides generated.

(2) Optimize: the number of steps in the linear Splines in the shape is reduced to 0. Because the number of steps is used to represent the curve, it is not required to accurately represent the straight line segment and can be removed. Optimize is the default setting. Optimize needs to be disabled when the target morph object is to be generated from the type.

(3) Adaptive: number of steps in each spline section in the Automatic calculation model. If the angle between Step 1 and Step 2 is greater than two, set the number of steps. The straight line segment has no steps.

Ii. UseEdit spline and editable spline objects

1. the edit spline object has all the functions of Editable spline and can be used to set object animation.

2. Use-Type Secondary object work:

By using the edit spline editing modifier or collapsing it into an editable spline object, you can enter its secondary object for editing. The following three types of secondary objects are available for selection and Editing:

(1) vertices; (2) segments; (3) Splines

3. Detach object ):

You can separate line segments and splines from a shape to create a new shape object.

4. Secondary object conversion: The Next object type uses the move, rotate, scale, and align conversion tools, similar to the tools used for the entire object through the editing modifier.

5. Edit at the object level (disable sub-object)

Attach, attach multiple (select multiple at a time), and create line operations can be performed.

6. Edit vertex ):

(1) conversion nodes: corner, smooth, bezy, and bezy corner.

(2) node operations A, connect, B, break, C, reline, D, insert ); e. Change it to the first vertex (mask first); F. Merge (weld ).

7. Online segment level editing (segment ):

Use the line segment attributes a, curve (curve), B, line (line)

1. Edit at the level of the spline(Sub-object à spline)

(1) closed spline (close)

(2) create an outline for a spline)

(3) Boolean operation: This command combines two source splines.

(4) image (mirror) spline step: A. Select a spline; B. Set whether to copy the checkbox as needed; C. Click the mirror axis button to set the direction of mirror; d. Click mirror.

3. Use-type editing Modifier

1. If an editing modifier is applied to the model but it is not visible, check its activation axis. If it is flat, the activation axis should be set to X or Y.

2. Convert the shape into a plane mesh: (1) collapse into an editable mesh. (2) All surface editing modifiers (such as normal, smooth, or material) can convert the shape to a grid. The surface editing modifier is simple and requires less memory than the Editable mesh modifier.

3. Extrude)

4. Rotating spline (lathe)

(1) set rotation axis: the default position is the Creation Center of the pass type, and the Creation Center is the location of the axis point when the type is created.

(2) changed axis point position: Do not use adjust minus to move the axis point. It is best to use Edit spline to move the position of the spline.

(3) control the rotating surface: A. degrees; B. segment number (segments); C. Merge center node (weld core ): A central node is a node that falls on the lathe axis. The central node of type is copied to each segment of rotation, resulting in many nodes stacked in the center of the rotating object, resulting in rendering errors.

5. bevel)

(1) level: divided into three layers: level1, 2, and 3; Set outlinel to set the width of the chamfer.

(2) method for processing the selected boundary: A. liner or curved sides. B. Smooth the hierarchy ).
