A 3D model on screen looks convincing, but without a dimensioned drawing each supplier may make it slightly differently. Technical documentation defines exactly what is correct and what is not.

What documentation contains

  • Part drawing: views, sections, dimensions, tolerances, surface roughness and material.
  • Assembly drawing: item numbers and a bill of materials with materials and quantities.

Why tolerances matter

Tolerances define how much a real part may deviate from the ideal shape and still work correctly. Without them, parts from different suppliers can match the drawing yet not fit together in practice. Tolerance values are always set according to the function of the part, not across the board.

When you need documentation

  • Production at several suppliers: each makes the same part from the same documents.
  • Certification and approval: some processes require formal documentation.
  • Selling or licensing a product: a partner needs an exact specification.
  • Service and assembly: assembly procedures and lists of components.
  • Quality control: comparing measured values with the specification.

Standards we work to

We prepare documentation according to the applicable standards for technical drawings. On request, we can also use a specific standard that your customer requires.

What if you do not have a 3D model

If you only have the physical part, we can measure it and produce a drawing from it, as in the project for a stand for a manufacturing company. For more complex shapes, it is advisable to combine measuring with 3D scanning.

Tip: Tell us what format you need for the output (for example PDF or an editable CAD format) before work begins.
