Surface Design (Sweep) - Surface Design (Join - Healing - Disassemble - Split - Trim - Boundary - Boundary - Extract - Translate - Rotate - Symmetry) - Surface Design (Scaling - Shape Fillet - Edge Fillet - Variable Fillet - Multi-Result Management)

Sweep:
From Surfaces toolbar click on Sweep. There are 4 methods of sweep. 


In this section the first method which is Explicit is considered. First select xy plane from specification tree. 


Then change the view in a way that it is normal to the xy plane. Click on Normal View button. Now the view is normal to xy plane.


Then double click on Point command from Wireframe toolbar. Point Definition window opens. Create point 1 (0,0,0) and click OK. 


Then from Point type list select 'On plane' option. In Plane section select xy plane. 


Click somewhere to create the second point.

Now two curves are created.


Now click on Sketch icon.


Then click on zx plane for sketch plane.

Click OK.


==========================================================
Disassemble:
In the example, the sketch (Sketch.1) consists of three different sketches.
