AutoCAD practice drawings for Mechanical Engineers with Free PDF eBook

Would you be willing to sharpen your AutoCAD skills for mechanical engineering applications? This article presents a collection of AutoCAD practice drawings specifically designed for mechanical engineers. These exercises include mechanical parts, sections, projections, and technical detailing used in real engineering design workflows.

You can also download the complete PDF eBook of these drawings for free to print or study offline.


Why Practice AutoCAD as a Mechanical Engineer?

AutoCAD remains a standard tool in mechanical design environments, especially for:

  • 2D mechanical part drafting
  • Technical detailing and dimensioning
  • Layouts for machining, fabrication, and assembly

These drawings will help you:

  • Learn standard projection methods
  • Improve geometric accuracy and dimensioning
  • Prepare for engineering coursework, jobs, or certifications

How to Use These Drawings

These exercises are image-based challenges. Here’s how to use them:

  • Open AutoCAD, set up your workspace in 2D drafting mode
  • Recreate each drawing manually based on the visual reference
  • Focus on proportions, constraints, and clean geometry

Use ISO or ANSI templates depending on your region’s drafting standards.


Here are sample exercises from the eBook. These include orthographic views, detailed dimensions, and cut sections.


Drawing #1 – Symmetrical Machine Part

Focus: Centerlines, Fillets, Hatching, Full dimensioning


Drawing #2 – Support Bracket with Holes

Focus: OFFSET, CIRCLE, ARRAY, HATCH, and LEADER tools


Drawing #3 – Front and Side Views with Section

Focus: Projection views, Section lines, Hatch pattern accuracy


Drawing #4 – Coupling Flange Drawing

Focus: Detail view, Hole placement, Dimension style

7 Tips to Complete These Mechanical AutoCAD Drawings Effectively

1. Always Use Construction Lines First

Start by building the geometry with XLINE and guides to align holes, centers, and cutouts precisely.

2. Use Object Snap and Midpoint Frequently

Precision is key in mechanical drawings — make sure your constraints are exact using OSNAP settings.

3. Layer Control is Important

Use separate layers for:

  • Dimensions
  • Centerlines
  • Hatching
  • Annotations

4. Keep Consistent with Dimensioning

Use either ISO or ANSI dimension standards, and avoid mixing units or styles.

5. Practice Hidden Line Conventions

Use dashed lines for features not visible in the current view. These are critical in mechanical drawings.

6. Use Fillet & Chamfer Commands

Apply realistic edges using FILLET and CHAMFER tools as per design intent or manufacturing standards.

7. Don’t Just Trace – Recreate!

Avoid the temptation to trace over an image. Rebuilding each drawing trains your spatial logic and improves mastery.
