1. Pad
The Pad command is the primary tool for creating a solid body from a sketch.
What it does: It extrudes (pulls) a 2D sketch into the third dimension to create volume.
How it works: You select a closed profile (like a circle) and define a length (height).
Analogy: Think of squeezing toothpaste out of a tube; the shape of the opening determines the shape of the "pad."

2. Boolean
Boolean operations allow you to combine, subtract, or intersect two separate solid objects.
What it does: It modifies shapes by interacting them with each other.
Common Operations:
Fuse (Union): Joins two objects into one single object.
Cut (Difference): Subtracts one object from another (like using a cylinder to cut a hole in a cube).
Common (Intersection): Keeps only the volume where the two objects overlap.

Workbench Note: While "Pad" is a Part Design tool, Boolean operations are most commonly found in the Part workbench. In Part Design, tools like "Pocket" are essentially automated Boolean cuts.
Common Use: Creating shafts, wheels, spheres, cones, or any "turned" part (lathe work).
