Mechanical Parts : Gear

Use Gear to create a gear model.

  • Create panel > (Geometry) > Mechanical Parts

  • ·         Then click Gear button

Interface

 

 

Keyboard Input

X,Y,Z – position of start creation.

Radius - Sets the radius of the gear.

Height - Sets the dimension along the central axis. Negative values create the gear below the construction plane.

Height Ths – Height of threads.

Number Ths – Number of threads.

Creation Method rollout

Edge - Draws the object from edge to edge. You can change the center location by moving the mouse.

Center - Draws the object from the center out.

Parameters rollout

Radius - Sets the radius of the gear.

Height - Sets the dimension along the central axis. Negative values create the gear below the construction plane.

Segments - Sets the number of segments around the gear. To create a smoothly object, use a higher number of segments and turn Smooth on.

Twist  - Twist the thread in degrees.

 

Cone  - Sets of cone form of sides in degrees.

Height Ths – Height of threads.

Number Ths – Number of threads.

 

Part A,B,C – parts of thread profile.

 

Smooth - Blends the faces of the gear, creating a smooth appearance in rendered views.

 

Generate Mapping Coords - Generates coordinates for applying mapped materials to the gear. Default=on.

 

Real-World Map Size - Controls the scaling method used for texture mapped materials that are applied to the object. The scaling values are controlled by the Use Real-World Default=off.

 

Parameters

 

 

Procedures

To create a gear:

  1. Drag the mouse to define the radius of the base of the gear.
  2. Release the mouse button, and then move the mouse vertically to define the height of the gear. Click to set the height.
  3. Click again to finish the gear.

Mapping texture coordinates

For an explanation of how it works, we take the square demo texture and apply it on the object with different options.
