NEW VERSION NANOCAD PRO 20 IS RELEASED!
It combines two approaches to 3D modeling - Parametric and Direct Modeling in a single modeling environment.
The first one is the typical MCAD tool for 3D solid modelling based on Construction History. It is similar to Autodesk Inventor or SolidWorks. There is a special 3D History Window in a 3D design environment containing a Construction tree representing a history of model creation. Construction tree is a sequence of features (actions) that create the model. 3D History is a nanoCAD Inspector window with a specific set of tools.
The second one - Direct Modeling offers designers a what-you-see-is-what-you-get approach to building and editing their models. nanoCAD Pro uses it with traditional tools for DWG-based CAD 3D solids creation and editing. It allows you to create basic solid primitives (box, cylinder, cone, sphere, pyramid, wedge, torus, polysolid) with editable properties and smart grips.
