10 Best CAD Practice Drawings
AutoCAD, Mechanical Engineering & 2D/3D CAD Exercises
For Beginners, Engineering Students and CAD Designers
Looking for CAD practice drawings to improve your technical drawing skills? Practising real engineering shapes helps you understand dimensions, geometric construction, orthographic views and mechanical components. This guide introduces 10 useful types of CAD drawing exercises you can practise using AutoCAD or a suitable 3D CAD application.
What Are CAD Practice Drawings?
CAD practice drawings are technical drawing exercises used to develop computer-aided design skills. They help learners understand how to create accurate shapes, follow dimensions, use drawing commands and prepare engineering drawings. These exercises are useful for students of mechanical engineering, diploma courses, ITI, product design and professional CAD training.
Depending on the exercise, you may work with lines, circles, arcs, fillets, chamfers, holes, slots and curved profiles. More advanced tasks involve 3D part modeling, sectional views and assembly design. You can start with simple geometry and gradually progress to complex mechanical components.

10 Best CAD Practice Drawing Exercises
1. Basic 2D Geometric Drawing
Start with rectangles, circles, arcs, polygons and connected lines. Practise accurate coordinates, object snaps and basic editing commands. This exercise is suitable for beginners learning AutoCAD 2D drawing and technical drafting.
Practise: LINE, CIRCLE, ARC, OFFSET and TRIM.
2. Mechanical Plate with Holes
Create a rectangular or irregular mechanical plate containing mounting holes, slots and rounded corners. Add centre marks and complete dimensions. This task helps you practise symmetry, spacing and accurate hole positioning.
Practise: CIRCLE, MIRROR, FILLET, DIMENSION and ARRAY.
3. Stepped Shaft Drawing
Draw a stepped shaft with different diameters, shoulders and specified lengths. Include a centreline and appropriate dimensions. This exercise is especially helpful for understanding shaft profiles used in mechanical engineering.
Practise: LINE, OFFSET, TRIM and linear dimensioning.
4. Flange and Bolt Circle
Design a circular flange with a central bore and equally spaced bolt holes. Use a bolt-circle construction to position the holes accurately. This drawing is useful for learning circular patterns and concentric geometry.
Practise: CIRCLE, POLAR ARRAY, CENTERMARK and DIMENSION.
5. Bracket and Support Drawing
Create a mechanical bracket with a base, upright section, mounting holes and rounded edges. Draw the front, top and side views to understand how one component is represented in orthographic projection.
Practise: OFFSET, FILLET, MIRROR and orthographic projection.
6. Isometric Mechanical Drawing
Convert a simple stepped component into an isometric representation. Focus on the visible edges, inclined surfaces and relative positions of features. This exercise improves your ability to interpret three-dimensional shapes from engineering drawings.
Practise: Isometric drafting, object snaps and line accuracy.
7. Sectional View Drawing
Prepare a sectional view of a component containing an internal hole or cavity. Use cutting-plane conventions and suitable hatching to communicate internal features clearly. Follow the drawing standards required for your course or workplace.
Practise: HATCH, SECTION, centre lines and technical annotation.
8. Revolved 3D Component
Model a rotational component such as a simple bush, pulley or turned part. Start with a suitable 2D profile and use a revolve feature in compatible 3D CAD software. Add grooves or bores only after the basic model is correct.
Practise: Sketch, Revolve, Extrude and basic feature editing.
9. Complex Curved Mechanical Profile
Choose a profile containing several arcs, different radii and connected edges. Reproduce the outline carefully using the dimensions shown in your reference drawing. This task develops precision and helps you understand tangent transitions.
Practise: ARC, FILLET, TRIM, tangent geometry and radius dimensions.
10. Mechanical Assembly Practice
Finish with a small assembly project, such as a coupling, vice or bracket assembly. Model the individual parts, position them correctly and check how they fit together. Use assembly tools only when supported by your CAD software.
Practise: Part modeling, assembly constraints, alignment and drawing views.
How to Practise CAD Drawings Step by Step
- Choose a drawing with clear dimensions and a suitable difficulty level.
- Set the correct units, drawing limits and workspace.
- Study the shape before starting the geometry.
- Create the main outline first, then add holes, slots and other features.
- Use object snaps and construction lines to maintain accuracy.
- Add dimensions, centre lines and hatching where required.
- Check the final drawing against the reference and save it in the required format.
Which CAD Software Can You Use?
AutoCAD: Suitable for 2D drafting, dimensions, layouts and many engineering drawing tasks.
SolidWorks: Useful for parametric 3D part modeling, mechanical components and assemblies.
CATIA: Commonly used for complex product design, surfaces, parts and assemblies.
Siemens NX and PTC Creo: Other options for 3D modeling, engineering design and assembly workflows. Available commands and features depend on the software and version.
