Parameterized design and technological elements database

Design and technological database contains a large collection of parametric and object-dependent elements, including three-dimensional ones.

When you change parameters of one part, all associated object-dependent parts change automatically, and in accordance with their database values. This is a powerful tool for multivariate design, which guarantee to improve the design quality.

3D solid modelling with 2D/3D constraints

nanoCAD Mechanica combines two approaches to 3D modeling - Parametric and Direct Modeling in a single modeling environment.
  • Parametric Modeling involves engineers building up a 3D geometry piece by piece. 2D sketches turn into 3D features, with constraints and relations duly applied to fit the designer’s intent. The history of construction forms 3D History Tree. 3D History is a nanoCAD Inspector window with a specific set of tools. This approach is common for MCAD applications (e.g. SolidWorks, Inventor). However, since each step follows from preceding steps, parametric design can require careful planning.
  • Direct Modeling offers designers a what-you-see-is-what-you-get approach to building and editing their models. In Direct Modeling, designers can push and pull on their model to change it. One benefit of this capability is the ease with which designs can be altered, enabling rapid iteration and prototyping.
    nanoCAD Mechanica combines this approach with traditional for DWG-based CAD 3D solids creation and editing of basic solid primitives (box, cylinder, cone, sphere, pyramid, wedge, torus, polysolid).
In addition to 2D constraints there are 3D constraints operating on geometry of objects in space. Using this tool designers can link 3D objects within one file, thereby providing the ability to create complex 3D assemblies. Applied constraints are displayed in the 3D History tree for each correspondent solid.
