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.

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.

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

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

BOM tools

Mechanica’s BOM tools create bills of material of parts linked to drawings. BOM tables can contain the following items:

  • Itemized specification numbers
  • Electrical specifications
  • Automatic receipt of specifications
  • Custom specifications
