VariCAD is a powerful, professional CAD application that offers a variety of features that allow you to create 3D or 2D drawings that are useful for engineering. With the comprehensive CAD software, designers can quickly create, evaluate and modify their models. The software is sold as a fully loaded package with all the features and functionality at a very reasonable price. VariCAD offers excellent value for money, making it one of the brightest options on the market today.
User Interface and System Environment The VariCAD graphical user interface (GUI) provides fast and intuitive 3D / 2D alignment. It has been carefully adapted and adapted to reflect the thinking 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 usability.
You can start creating a 3D model and then use it to automatically create drawing files, or you can only draw in 2D. Designing in 3D is generally more "natural" as it accurately represents the actual parts and assemblies. The 3D approach is usually more intuitive than 2D drawing. Models created in 3D can easily be converted to traditional 2D documentation. VariCAD provides tools for 2D updates after changes to 3D models.
VariCAD provides a library of basic 3D shapes (such as boxes, cylinders, cones, etc.) that can easily be changed by editing the dimensions. Solid can also be created by profile rotation, extrusion, or lofting. More complex tools include rotation blending between two profiles, lofting between a circle and a rectangle or between different profiles, and creating spiral surfaces.
Solids can be added or subtracted, forming Boolean trees that represent real mechanical parts. Boolean operations have the ability to trim automatically (so-called selective Boolean operations). Predefined operations such as hole drilling, face milling or slot milling are also available. Edges may be rounded or bevelled. VariCAD offers many possibilities for solid transformations or their processing. You can also easily edit Boolean trees by either selecting fixed parts from 3D or selecting them from a list of trees.
Parameters and geometric constraints
Although you can comfortably transform solids or their parts, you can optionally define geometric dependencies. After defining constraints, you can "hold" the object at a defined position. More specifically, you can remove the degrees of freedom of restricted objects. When other objects are changed or transformed, a restricted object automatically changes its position. For example, if you hold a groove to the end of a shaft and the wavelength changes, the groove remains at a constant distance from the end edge. Dependencies can be defined between members of a solid, between solids, or within a 2D profile to create a solid (eg, by extrusion).
When you enter a dimension, a distance by constraint, or a dimension in a 2D profile that is used to create bodies, you can optionally use parameters or even a math expression that contains parameters. If you change parameter values, you can change shapes or positions of bodies.
3D assemblies and groups
VariCAD also offers tools for mounting support. When the connection between a part and an assembly is defined, any changes to the part file are reflected in the assembly file, and vice versa. Linked copies of solids can also be defined (so-called identical solids). In this case, editing an object will update all identical copies. Volume groups can also be defined, which simplifies selection and visibility for multiple objects.
VariCAD can calculate 2D interface, surface, volume, mass, center of gravity, and moment of inertia. The calculation of mechanical parts is also included – for standard parts used by designers daily. There are calculations on compression and compression springs, preloaded screw joints, pins and feather keys, groove shafts, bearings, beams under combined load (bending and torsion), bevel and bevel gear geometry as well as belt drives.
Surface development (sheet bending)
VariCAD can also create developed (unbending) surfaces of 3D solids or sheet metal parts. The XY coordinates of developed surfaces can be stored in a text file for further processing. You can enter bending coefficients to adjust your calculations and reflect material and technology.
Mechanical Parts and Symbol Libraries VariCAD includes libraries of standard mechanical parts (ANSI, DIN), eg. As bolts, nuts, pins, plugs, seals, bearings, rolled and drawn forms and hydraulic, pneumatic and electrical symbols.
3D – 2D export
3D models can easily be converted to 2D drawings to create traditional drawing documentation. You can create 2D views of one or more selected solids by defining the views in 3D. You can also export certain sections. VariCAD supports updates to a 2D drawing after changes in 3D.
2D drawing and editing
The drawing functions are optimized for easy use in engineering. The handy features of the 2D drawing include: automatic detection of objects and snap points, numerous snap modes, construction guides, ortho mode, rectangle grids, drawing planes, block creation, auto-edge hatching, advanced dimensioning, finishing symbols, welding symbols, tolerance symbols, and more , You can draw in millimeters or inches.
BOM and title blocks
VariCAD provides tools to maintain the data structure of the product. There are links between attributes of parts and content of caption fields. You can create a BOM from an assembly, or simply modify the database using commands such as mass attribute changes, information sorting, and so on. Each part can contain attributes such as name, material type or supplier. This data can be used for material requirements, creating bills of material, filling in caption fields, or other purposes.
The data structure of the product (BOM) can be exported to other systems or to a spreadsheet. BOM customization uses a mask. You can customize it exactly to your needs. Mask defines the use of solids or assembly attributes, working with title blocks, methods for exporting data from BOMs, and so on.
VariCAD can exchange files with other CAD systems. You can export STEP (3D), STL (3D), IGES (3D), DWG (2D), DXF (2D) files, and STEP (3D), DWG (2D), DXF ( 2D) import. The files can be converted individually or in batch routines, which converts multiple files in one step.
This version supports 3D mouse under Linux. VariCAD commands are available via 3D mouse buttons. Next, isometric views in 3D mode and 2D objects are created from data loaded from * .csv files, or generally text files (XY coordinates files). The UI includes a virtual numeric field available for entering values, and newly created dialog boxes used to define primitives (such as boxes, cylinders). The new version has improved parts of the 3D kernel, including the input / output of STEP files.
