Examples of spindles
Procedure
To create a spindle:
1.
FromtheCreatemenu,chooseExtended
Primitives > Spindle.
2. Drag the mouse to define the radius of the base
of the spindle.
3. Releasethemousebutton,andthenmovethe
mouse vertical ly to define the height of the
spindle. Click to set the height.
4. Mov e the mouse diagonally to define the height
of the conical caps (toward the upper left to
increase the height; toward the lower ri ght to
decrease it).
5. Click again to finish the spindle.
Inter face
Creation M ethod rollout
Edge—Draws the object from edge to edge. You
can change the center lo cation by moving the
mouse.
Center—Draws the object from the center out.
Parameters rollout
Radius—Sets the radius of the spindle.
Height—Sets the dimension along the central
axis. Negative values create the spindle below the
construction plane.
Cap Heig ht —Sets the height of the conical caps.
The minimum value is 0.1; the maximum value is
½ the absolute value of the Height setting.
Over a ll /Centers—Determines what the Height
value specifies. Overall specifies the overall height
of the object. Centers specifies the height of
the midsection of the cylinder, not including its
conical caps.
Blend—When greater than 0, creates a fillet where
the caps meet the body of the spindle.
Sides—Sets the number of sides around the
spindle. Higher numbers shade and render as true
