VariCAD的緊湊，速度快，使用方便，並提供一切需要的機械設計。
VariCAD的被賣「滿載」，內含所有的特性和功能，一個實惠的價格。 CAD系統提供卓越的效能 – 價格比。
您可以通過建立一個三維模型，然後用它來自動建立繪圖檔案，或是你可以只繪製2D。
在3D設計一般是更「自然」的，因為它密切指實際零件和裝配體。
3D的做法通常是更直觀的2D繪圖。在3D中建立的模型很容易轉換成傳統的2D檔案。
3D建模
VariCAD的提供了一個基本的3D固體（稜柱，圓柱，圓錐等），這是很容易地修改通過編輯原始配置檔或參數庫。
固體也可以很容易地建立，輪廓旋轉，擠壓，或放樣。

VariCAD 2013 2.07
VariCAD is a 3D/2D CAD system for mechanical engineering. In addition to standard tools for 3D modeling and 2D drafting, the CAD system provides support for parameters and geometric constraints, tools for shells, pipelines, sheet metal unbending and crash tests, assembly support, libraries of standard mechanical parts (ANSI, DIN) and symbols, mechanical part calculations and tools for working with bills of materials (BOM) and title blocks. VariCAD supports STEP, STL, IGES, DWG and DXF file formats. VariCAD is compact, fast, easy to use, and provides everything one needs for mechanical design. VariCAD is sold “fully loaded”, including all features and functions, for one affordable price. The CAD system delivers an excellent performance-to-price ratio.
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.
Mechanical Part and Symbol Libraries
VariCAD contains libraries of standard mechanical parts (ANSI, DIN), such as bolts, nuts, pins, plugs, cotters, gaskets, bearings, rolled and drawn shapes, and hydraulic, pneumatic, and electronic symbols. You can add items to these libraries or modify existing parts – all 2D and most 3D dimensions can be edited.
Non-graphical information can also be assigned to parts, such as type of material or supplier. This information is incorporated into an assembly and can be used for material requisitions, bills of materials (BOM), title blocks, or other purposes.
3D – 2D Export
3D models are easily converted into 2D drawings to produce conventional drafting documentation. You can create 2D views of one or more selected solids by defining the views in 3D. In addition, you can also export specified sections. VariCAD supports updates of a 2D drawing after changes in 3D.
2D Drawing and Editing
Drawing functions are geared toward easy use in engineering. Some handy features of 2D drawing include: an intelligent cursor that automatically detects objects and snap points, numerous snap modes, flexible item selectability, auxiliary construction lines, ortho mode, rectangular grid, drawing layers (up to 250), block creation, hatching with automatic border detection, advanced dimensioning, surface texture symbols, welding symbols, tolerance symbols, and more. Dimensions can be in millimeters or inches.
BOM and Title Blocks
VariCAD provides tools for maintaining drawing databases, which represent the data structure of the product. Databases can be created manually (using data extraction from the assembly), or by loading a file. There are constraints between data in part and assembly drawing title blocks and the assembly database. You can build a bill of material (BOM) from the database, then easily modify the database using commands like mass attribute changes, sorting of information, etc.
The data structure of the product (BOM) can be exported into other systems or into a spreadsheet. Automatic BOM and title block creation is another one of VariCAD’s useful tools. A mask is used for customization; if you create masks for BOM and title blocks, you can use them until a change is necessary. The CAD system provides default masks which can be adjusted to suit your needs.
Compatibility
VariCAD can interchange files with other CAD systems. You can import STEP (3D), DWG (2D), DXF (2D) and IGES (2D) files, and export STEP (3D), STL (3D), IGES (3D and 2D), DWG (2D), DXF (2D). The files can be converted individually or in batch routines, thereby converting multiple files in one step.
Printing and Plotting
Printing within VariCAD is highly customizable. You can use Windows or KDE Linux printer drivers, or VariCAD built-in drivers. Postscript printing is also available.
Summary
VariCAD is a total CAD solution for mechanical engineering. It is compact, fast, easy to use, and contains everything you need for mechanical engineering design. The high performance and powerful tools of our fully loaded package make VariCAD a superb investment. And at our price, no other product is a better value.
