VariCad 2011 is a powerful 3D/2D CAD solution that offers an intuitive and user-friendly interface. With its comprehensive set of tools, users can create precise technical drawings, 3D models, and animations with ease. The software supports a wide range of formats and offers advanced features, such as parametric constraints and 3D printing support. VariCad 2011 is an essential tool for engineers, architects, and designers looking for a reliable and efficient CAD software for Windows 7.

VariCAD is 3D/2D CAD system primarily intended for mechanical engineering design. In addition to powerful tools for 3D modeling and 2D drafting and dimensioning, the CAD system provides libraries of standard mechanical parts (ANSI, DIN), calculations of standard mechanical components, and tools for working with bills of materials (BOM) and blocks. The comprehensive CAD software enables designers to quickly create, evaluate, and modify their models. VariCAD's high performance, powerful features, and simple and quick user interface make VariCAD the best value in the CAD market. The software is sold as one "fully loaded" package, with all features and functions, for one very affordable price. VariCAD delivers an excellent performance-to-price ratio, making it one of the smartest choices on the market today.

User Interface and System Environment
VariCAD's Graphical User Interface (GUI) has been designed to allow quick and intuitive 3D/2D orientation. We carefully tailored and tuned the GUI to reflect the thought process of a designer, so that ideas can be captured and communicated with a minimal number of steps. All commands were created with a focus on ease of use. An intelligent cursor, numerous detection and selection modes, 2D construction lines, and the orthogonal grid are just some of the tools that make working with VariCAD so easy.

You can start by creating a 3D model and then use it to automatically create drawings files, or you can draw only in 2D. Designing in 3D is generally more "natural," in that it closely represents actual parts and assemblies. The 3D approach is usually more intuitive than 2D drafting. Models created in 3D are easily converted into conventional 2D documentation.

3D Modeling
VariCAD provides a library of basic 3D solids (prism, cylinder, cone, etc.), which are easily modified by editing the original profile or parameters. Solids can also easily be created by profile rotation, extrusion, or lofting. More complex tools include rotation blending between two profiles, lofting between a circle and rectangle, and creation of helical surfaces.
Solids can be added or subtracted, thus forming Boolean trees representing real mechanical parts. Boolean operations have options for automatic trimming, or automatic removal of subtracted volumes. Predefined operations like hole drilling, face milling, groove milling and edge beveling/filleting are also available. Boolean trees are very easy to edit.

3D Tools - Assemblies, Groups, Parts etc.
VariCAD also provides tools for assembly support. If the link between a part and assembly is defined, any changes made to the part file are reflected in the assembly file and vice-versa. Linked copies can also be defined. In this case, editing of one object causes all its linked copies to be updated. Solid groups can be defined as well, making selection and visibility changes simple for multiple objects.

Crash Tests (Interferences)
One excellent feature of 3D modeling is component interference checking. VariCAD can check 3D assemblies for possible collisions (overlapping volume) between components.

Calculations
VariCAD can calculate 2D section area, surface area, volume, mass, center of gravity, and moment of gyration. A library of mechanical calculations is also included, for standard parts used every day by mechanical designers. These mechanical parts include tension and compression springs, pre-stressed bolted connections, pins and parallel keys, grooved shafts, bearings, beams under combined stress (bending and torsion), spur and bevel gearing geometry, and belt drives.

Surface Development (Sheet Metal Unbending)
VariCAD can also create developed (flattened) surfaces of 3D solids. The XY coordinates of the developed surfaces can be saved to a text file for further processing. You can input bending coefficients in order to customize your calculations.

New Release
· The new version 2011-1.0x contains rebuilt and significantly better DWG/DXF interface, new or changed 2D functions, better support of 2D NURBS objects (splines), significantly improved user interface and improved STEP input.
· The DWG/DXF interface supports file formats from AutoCAD 2011 down to R12 and works with wider range of objects in comparison with previous versions.
· The 2D module contains improved working with NURBS curves, including their editing, improved working with user-defined blocks or symbol libraries, changed hatch functions and editing of existing hatches, and new edit functions like changing line lengths or arc radii.
· User interface contains new features like displaying coordinates nearby the cursor, multiple options during 2D location input. User interface contains also convenient methods of keyboard inputs, entering fixed lengths, radii, angles or coordinates.
