Master AutoCAD Projection Sketching: A Beginner's Guide

AutoCAD projection sketches are a great way to create 2D drawings of 3D objects. They can be used for a variety of purposes, including architectural drawings, mechanical drawings, and product design. This worksheet will provide you with the basic steps on how to create AutoCAD projection sketches. We will also provide you with some examples of projection sketches and some tips on how to use them effectively.

Projection sketches are created by projecting a 3D object onto a 2D plane. The most common types of projections are orthographic projection, isometric projection, and perspective projection. Orthographic projection creates a drawing that shows the object from the front, side, and top. Isometric projection creates a drawing that shows the object from a 30-degree angle. Perspective projection creates a drawing that shows the object as it would appear to the human eye.

Examples of AutoCAD Projection Sketches

Here are some examples of AutoCAD projection sketches:

1. Orthographic projection of a cube
2. Isometric projection of a sphere
3. Perspective projection of a house
4. Orthographic projection of a machine part
5. Isometric projection of a furniture piece

Guidelines to Create AutoCAD Projection Sketches

Here are the steps on how to create AutoCAD projection sketches:

1. Start by creating a new AutoCAD drawing.
2. Select the “View” tab and then click on the “Projection” button.
3. Select the type of projection you want to use.
4. Click on the “OK” button.
5. Use the AutoCAD commands to draw the object.
