Knowledge Base for Product Owners

Dear Product Owner, the Werk24 knowledge base is written for you! It is designed to (i) give you an overview of the edge cases to consider when processing information from Technical Drawings, and (ii) explain which aspects can have a business impact.

Dear Developers, you’ll also find mechanical engineering principles that help when working with information extraction from Technical Drawings. For more technical discussion, see our documentation →.

Core Topics

Each concept below highlights why it matters for quoting, production, and business impact.

Measures

  • EU
  • US
  • Spherical Diameter
  • Diameter
  • Chain Dimensions
  • Ascending Dimensions
  • Angular Dimensions
Measures describe the ideal lengths and deviations allowed before a part becomes useless. Ignoring tolerances produces parts that look right but don’t fit together.

Projection Methods

  • US vs EU
  • First/Third Angle
Projection Methods define how 3D objects are projected to 2D drawings. Different markets use different methods. Ignoring them results in mirrored, useless parts.

Radii

  • Fillets
  • Stress relief
Radii describe curvature and smoothness. Sharp corners cause stress and are hard to machine. Ignoring radii risks part failure.

Threads

  • Diameter
  • Pitch
  • Direction
Thread readings include diameter, pitch, length, and more. Multiple standards exist. Ignoring differences may result in unmanufacturable parts.
