nanoCAD Mechanica - A mechanical engineering software

nanoCAD Mechanica is a mechanical engineering tool with 2D drafting and 3D mechanical designing. It is based on an advanced parametric engine, and works with a large library of standard parts. It enables users to carry out fast development of high-quality mechanical engineering drawings and project documentation.

  • Checks spelling with built-in text editor
  • Creates tables with built-in table editor

Parameterized parts database

Mechanica’s parts database contains a vast collection of parametric and object-dependent elements, including three-dimensional ones. When you change the parameters of a part, all associated parts in the drawing also change automatically, according to their database values. This powerful tool generates design variations, which improve the design quality.

Designing bolted and riveted joints

Mechanica offers flexibility in handling bolt and rivet functions:

  • Connect groups of parts with arbitrary thickness using bolts, screws, or studs
  • Connect parts of arbitrary thickness with rivets displayed in regular and high accuracy, made of hollow and semi-hollow rivets
  • Display simplified fasteners in joints
  • Generate patterns of bolts and rivets in joints

Standards-based engineering drawings

With Mechanica, you quickly make drawings based on international standards using these tools:

  • ISO-standard fonts, line types, and dimension styles
  • Tolerance zones and deviations for dimensions and fits
  • Form and plane position tolerances
  • Surface texture symbols
  • Gradient symbols
  • Editor for writing and changing technical notes and specifications
  • Hole tables
  • Semi-automatic views, cuts, sections, and breaks
  • Auto-sorting letter labels of drawing elements
  • Fixed joint symbols
  • Marking and branding
  • Formats and stamps
  • Special arrays
  • Cross-referencing drawing denotations in technical requirements
  • Generation of table reports, with automatic updating of tables linked to drawing objects
