The Axis of Revolution

REVOLVE:

It creates a feature or new solid body by rotating on or more sketched profile around an axis. The profile can be revolved through any angle measuring between zero and 360 degrees around an axis. The axis of revolution can be part of the profile or offset from it. The profile and axis must be coplanar.

SIGNIFICANCE:[pic 1]

• Revolved assembly features can cut through other parts.
• You can create a surface from a revolved profile, and then use it as a termination plane for other features, or a split tool for a split part.
• Less time is required
• Complex structure can be made and mashing is done with ease.

PITCH:

It is the distance between the two-consecutive thread or section.

SIGNIFICANCE:

• It helps in making thread or helical cut.
• It is user’s friendly and fast.

MIRROR:

Creates a mirrored copy of selected object through a symmetrical or centre line. You can create objects that represent half of a drawing, select them, and mirror them across a specified line to create the other half. To use the mirror tool, select all of the entities you wish to mirror, click on the mirror tool icon, and then click on the centerline that acts as the mirroring plane.

SIGNIFICANCE:

• Using mirror command model can be made fastly.
• This command is especially useful when creating symmetrical objects.
• It allows you to either keep or delete the original object during the operation.

EXTRUDE:

It creates a 3D solid from an object that encloses an area, or a 3D surface from an object with open ends. Objects can be extruded orthogonally from the plane of the source object, in a specified direction, or along a selected path.

An Extrude is created by taking a sketch and pulling that sketch in a straight direction to a specified depth. Within the extrude feature, you can create solid protrusions, thin protrusions, solid cuts, thin cuts or surfaces, and can switch back and forth between these. 

SIGNIFICANCE:

• You can check either your model is enclosed or not.
• It is fast, easy, and less costly.
• You can edit your depth at any time.
• Errors can be fixed.

WIRE FRAME:

 A 3D wireframe model is an edge or skeletal representation of a real-world object. 3D wireframe models consist of points, lines, arcs, circle, and other curves that define the edges or centre lines of objects.

SIGNIFICANCE:

• Generate basic 3D designs for evaluation and fast design iterations.[pic 8]
• You can view the model from any viewpoint.
• Generate standard orthographic and auxiliary views automatically.
• Act as reference geometry for 3D solid, surface, and mesh modelling.
• It can be used to see perspective view.

SHELL:

• The SHELL sub-command converts a 3D solid into a hollow shell with a wall of wanted thickness. It creates a shell by removing a surface from a solid object. The shell created has specific wall thickness. [pic 9]

SIGNIFICANCE:

• It is an easy method to make your part hollow.
• Less effort is required simply you select it and click on the part.

HELICAL SWEEP:

Helical sweeps are used to create features such as threads and springs. We must define a trajectory, a section, and a pitch to create a helical sweep. The trajectory defines the path along which the section, or the profile of the thread, will be swept. The pitch defines the centre-to-centre distance between sections along the trajectory. The distance of the trajectory from the center line defines the radius of the helical path and the length of the trajectory defines the length of the swept feature. The main use of this option is to create the helical springs and threads.[pic 10]
