In this CAD tutorial we'll use the features:
1. Extrude
The Extrude command is the most basic tool for creating 3D geometry.
Action: It pushes or pulls a 2D sketch along a straight line into 3D space.
Function: Depending on the software mode, it can either add material (creating a solid body) or cut material away (like a Pocket).
Typical Use: Creating blocky, prismatic base shapes like cubes, plates, or straight cylinders.
2. Revolve
The Revolve command is the primary tool for creating round, symmetrical objects.
Action: It takes a 2D sketch profile and spins it $360^{\circ}$ (or a specified angle) around a center axis.
Typical Use: Creating cylindrical or spherical parts that could be turned on a lathe, such as shafts, wheels, pipes, or bottles.
3. Offset Plane
An Offset Plane is a piece of reference geometry (construction tool).
Action: It creates a custom, invisible flat surface that is perfectly parallel to an existing face or standard plane (XY, XZ, YZ), but pushed away by a specific distance.
Why use it? If you need to sketch a feature that starts floating 50mm above your part, or you need a plane to act as a target for a Loft, you create an Offset Plane there first.
4. Loft
The Loft command creates complex, transitional 3D geometry.
Action: It builds a solid body by creating a smooth transition (morphing) between two or more different sketch profiles located on different planes.
Requirement: At least two sketches. For example, a square sketched on the ground plane, and a circle sketched on an Offset Plane high above it.
Typical Use: Creating organic, aerodynamic, or ergonomic shapes where a simple Extrude won't work—such as boat hulls, airplane wings, or vacuum cleaner nozzles.
All dimensions are in mm/g/s/ISO
