Training process

Training needs analysis

If you have specific requirements regarding the training programme, we will carry out a training needs analysis for you. This will guide us on which aspects of the programme should receive greater emphasis, so that the training programme meets your specific needs.

What will you gain?

icon

Clear drawings from the start - You will learn how to choose scales, line types and sheet formats correctly, so you can prepare technical drawings that are clear, standards-based and easy for others to read.

icon

Confident use of projections - You will master orthographic projection of shapes and solids, helping you read building documentation faster and present objects independently in correct technical views.

icon

Presenting solids in space - You will practice axonometry, isometry and oblique dimetry, which will help you show the form of elements more clearly and understand their spatial arrangement on drawings.

icon

Better understanding of sections - You will learn how to create sections, partial views, and complex or developed sections, so you can show internal structure correctly and avoid common reading mistakes.

icon

Accurate dimensioning - You will learn dimensioning rules, fits and tolerances, so your drawings will define dimensions unambiguously and make it easier to manufacture or verify elements in practice.

icon

Correct technical symbols - You will learn surface roughness and shape markings, so your drawings will include the key technical information needed during execution, inspection and quality control.

icon

Showing part connections - You will learn how to represent threaded and welded joints, allowing you to show how elements are connected clearly and discuss technical solutions more effectively with contractors.

icon

Greater design independence - Through practical exercises, you will work on geometric constructions, intersections and interpenetration of solids, so you can handle building documentation tasks with more confidence.

  • intersections of solids with planes,
  • interpenetration of solids.

4. Sections, intersections and developments of solids

  • sections and partial views,
  • compound and developed sections,
  • intersection,
  • revolved sections.

5. Dimensioning of drawings

  • principles and types of dimensioning,
  • fits and tolerances,
  • dimension tolerancing in drawings,
  • form and position tolerancing.

6. Markings on the drawing

  • surface roughness markings,
  • shape markings.

9. Practical exercises

10. Training summary

What are the prerequisites for participating in the training?

icon

Basic geometry - You should be comfortable identifying basic shapes and solids and understand concepts such as angles, parallel lines and perpendicularity, as they will be used throughout.

icon

Comfort with drawing work - You should be able to analyze a simple drawing carefully and transfer information onto paper, because the training includes exercises that rely on accuracy.

icon

Accuracy and patience - You should be ready to work precisely with detail, because correct drafting, dimensioning and marking of elements require focus, consistency and careful execution.

icon

Basic construction knowledge - It is helpful if you know basic terms related to building elements and documentation, so you can understand the examples used during the training more quickly.
