Extrude Revolve ORDERS AND ORDERS IN AUTO CAD BY BUDI M

Extrude command in AUTO CAD function to change the thickness of a 2 -dimensional object . In the Extrude command can only be used on a closed polyline , polygon , circle , Ellipse , by way of command united through the region . Extrude command can not be used for line or polyline arc and also to segment and intersecting objects consisting of block can not be used extrude command . The general form of this command is

Command : extrude ( enter)

Current wire frame density : isolines = 4

Select objects to extrude : 1 found

Select objects to extrude : ( select the object to be bold )

Specify height of extrusion or [ Direction / Path / Taper angle ] < 60.0000 > ( specify thickening of the

                                                                                                                     desired )

Specify angle of taper for extrusion < 0 > : ( specify the value of the tilt angle of the field

                                                                           filled with bold numbers)

Example : Figure 3 dimensional form the straight gears , which in bold Z-axis , through the Extrude command

Extrude command that is given to the object straight gears will make the object has a height in the upright direction , ie in the direction of the Z axis

ORDERS Revolve
Revolve command in AUTO CAD serves to thicken the form of 2 -dimensional manner in the play , this command is generally used to draw silender forms are hollow and also forms silender silender with different diameters in one silender .
In order revolve or extrude command , which will form images in bold to extrude or revolve command must form a closed curve , because if the open curve in the region when the value of the loop region extracted and created value will be 0 ( zero ) .

Unlike the Extrude command , the command revolve in AUTO CAD , AUTO CAD users need help lines as the location of the X axis ( axis ) so that the direction of thickening in get in way round in the Y axis ( axis ) to determine the value of the rotation of the shape - silender forms are perforated and also forms silender silender with different diameters in one silender , and the user must also specify the amount of the value of the angle of the rotating form .

The general form of the command is the revolve .

Command : revolve

Current wire frame density : isolines = 4

Select objects to revolve : 1 found

Select objects to revolve : ( select objects that have been in the region)

Specify axis start point or define axis by [ Object / X / Y / Z ] <Object> : ( click on the starting point of the axes

Specify axis endpoint : click the finish point of the axis )

Specify angle of revolution or [start angle ] < 360 > : ( input angle values ​​are in bold workpiece by way of playing )
