1. Pad
The Pad command is used to create a solid from a 2D sketch.Action: It extrudes (pulls) a sketch into the third dimension.Typical Use: turning a rectangle into a box or a circle into a cylinder.
2. Pocket
The Pocket command is used to remove material from a solid.Action: It cuts a shape into an existing object based on a sketch.Typical Use: Creating holes, slots, or recesses.
3. Fillet
