nanoCAD’s 3D Modeling module extends the nanoCAD platform with direct and parametric modeling. It is designed to construct 3D assemblies with 3D constraints and xrefs, and to handle sheet metal modeling.
nanoCAD’s 3D constraints impose dependencies on geometry, mostly commonly to assemble parts into a single model. Using these tools, engineers create complex 3D assemblies by linking 3D objects. There are five 3D constraints available: Mate, Insert, Angle, Tangent, Symmetry. Constraints for every part are displayed by the 3D History Tree.
nanoCAD’s parametric modeling mode allows engineers to build up 3D geometry, piece by piece. This approach to design is common among most MCAD applications, including SolidWorks and Inventor. As 2D sketches are turned into 3D features, engineers document their design intent through constraints and geometric relationships.
nanoCAD displays commands in groups for each type of modeling it offers: parametric, direct, sheet metal, and meshing. For example, while in parametric modeling mode, commands for creating 3D geometry based on parametric sketches are displayed; upon switching to mesh modeling, commands for creating 3D surfaces become available.
The associative relationship of models and their projections allows users to concentrate on designing in a 3D environment, paying attention to 2D graphics mainly for drawing design. All changes to the 3D model at any time will be displayed in the drawings, and the design elements made in 2D graphics will also correspond to these changes.
