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

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

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

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

Other important features

Dimension styles

Mechanica supports dimension styles, which are named collection of dimension settings that control the appearance of dimensions, such as the arrowhead, the text placement, and display of tolerances. It includes styles preset for a number of local and international standards.

Detail views with automatic updates

Mechanica generates detail views as objects that are updated by the MCREGEN command when the source model changes. When at least part of a scaled object falls into the view frame, then its scale is applied to the entire detail view.

MechWizard parameterizer

Mechanica’s MechWizard guides users through advanced functions:

  • Overlaying assembly and parametric dependencies on objects
  • 'Behavior training' of standard parts
  • Modification of database elements
  • Custom database elements

Calculation wizard

Mechanica’s powerful engineering calculators handle gear strengths, complex cross-sections of geometric properties with arbitrary axes, fasteners, bearing life at given load conditions, and more. Results of calculations are generated automatically as reports that show all formulas and ISO references used for the calculations.
