Telecurso 2000 - Leitura e Interpretação de Desenho Técnico - 13 Corte composto

Introduction

In this tutorial, you will learn how to effectively represent a compound section cut, also known as a "corte composto" or "corte em desvio," in technical drawing. This method is essential for visualizing internal features of components that are not aligned. Understanding this technique is crucial for anyone involved in technical drawing or design, enhancing your ability to communicate complex ideas clearly.

Step 1: Understand the Concept of Compound Cuts

• A compound cut is used to illustrate internal elements that are misaligned.
• It allows for a clearer representation of features that cannot be shown accurately with a standard cut.
• Familiarize yourself with the term "corte em desvio," which refers to the same concept.

Step 2: Analyze the Piece to be Drawn

• Examine the object you want to represent.
• Identify the internal features that are misaligned.
• Take note of the dimensions and angles relevant to these features.

Step 3: Prepare Your Drawing Tools

• Gather the necessary tools:
  • Graph paper or CAD software
  • Pencil or digital drawing tools
  • Ruler and compass for precise measurements
• Ensure you have a good understanding of the drawing conventions used in your field.

Step 4: Sketch the Basic Shape

• Start by drawing the external outline of the piece.
• Use light pencil strokes to allow for adjustments.
• Ensure proportions are correct to facilitate accurate representation of internal elements.

Step 5: Indicate the Cutting Plane

• Draw the line that will represent the cutting plane.
• Use dashed lines to indicate where the cut will occur, and label it clearly.
• Consider how this plane will affect the visibility of internal features.

Step 6: Show Internal Features Using Compound Cuts

• Begin adding the internal features based on your analysis.
• For misaligned elements:
  • Illustrate them from different angles or segments.
  • Use arrows or annotations to clarify their positions.
• Make sure to maintain consistency in line weight and style.

Step 7: Finalize the Drawing

• Review your drawing for accuracy and clarity.
• Darken the final lines, and erase any unnecessary construction lines.
• Add any labels, dimensions, and notes that will help others understand your drawing.

Conclusion

By mastering the technique of compound cuts, you enhance your ability to communicate complex internal structures in technical drawings. This skill is invaluable in engineering, architecture, and design fields.
