VariCAD是一款適用於機械工程設計的Windows/Linux雙平台CAD設計軟件，它不僅包含標準的2D工程圖繪制和3D建模等功能，還提供了利用參數和幾何約束來控制對象、以及創建帶有厚度的外殼、創建智能管道、展開曲面、幹涉檢查、內置ANSI與DIN標準的2D與3D機械零件庫等許多實用功能。VariCAD可以創建單獨的零件文檔以及裝配體文檔並在它們之間協同工作和同步更新，還擁有創建物料清單以及自動填充2D圖紙標題框等功能。VariCAD支持STEP、STL、IGES、DWG和DXF格式的文檔。
VariCAD軟件簡單易用，即使是初學者也可以很快地掌握利用VariCAD來創建設計對象、修改編輯、以及測算和評價設計對象的方法。最重要的是，VariCAD軟件是一款“全包形式”的軟件，它本身即提供了如上所述從事機械設計所需的全部功能，您無需額外付費購買其它插件，在目前的全球機械工程設計領域，VariCAD堪稱性價比最高的CAD解決方案。國外用戶形象地稱其“值得我們所付的每一分錢”。
2011年7月17日最新發布：VariCAD 2011(1.10)。新版本的VariCAD在針對DWG/DXF文檔的兼容性上獲得了全面提升、改善並增加了部分2D功能、能夠更好地支持Nurbs曲線（漸開線），此外還包括明顯改善的用戶操作界面和改善的STEP輸入功能。
全面提升的DWG/DXF文檔兼容性：
● 全面支持自AutoCAD 2011直至AutoCAD R12的DWG文檔
● 支持和識別種類更廣泛的2D對象、圖符
● 可供選擇的打開多種圖紙空間的方式
● 更加簡單而直接的自動檢測文檔錯誤功能
改善並增加的2D功能包括：
● 2D填充，包括自動探測填充區域的邊界線、編輯已有填充的樣式等
● 創建用於3D拉伸、旋轉等操作的外輪廓圖形
● 2D圖形面積測算，可用來測算剖面面積、外輪廓周長、轉動慣量以及彎曲系數等
● 支持預定義的2D圖塊
● 支持預定義的2D符號庫
● 全面支持2D的NURBS曲線（漸開線），包括如剪切、拆分、移除線段等
● 更好的2D偏移功能，包括對含有直線、圓或弧、NURBS曲線的多元線的偏移
● 新增的2D編輯功能，包括更直觀地編輯直線長度並以此來扭曲對象，更直觀地編輯圓或倒角的半徑等
● 更加豐富的2D多元線繪制功能選項
● 完善了2D偏移功能
● 完善2D填充繪制、2D填充編輯功能選項
用戶操作界面的改善：
● 可以在光標附近動態顯示其坐標值，如在2D繪圖時顯示X\Y坐標值、DX\DY數值、距最後點的角度和間距，或在3D移 ● 動實體時動態顯示間距和角度
● 更多的2D定位選項，可在定位操作過程中啓用鍵盤輸入數值
● 在2D定位過程中，可以按下TAB鍵來啓用鍵盤輸入數值，從而實現對間距、半徑、角度、坐標值等的精確定位
● 在2D或3D定位過程中，可以很方便地通過單擊鼠標右鍵來彈出相應的子功能菜單
● 在對象上單擊鼠標右鍵可以彈出更多的操作功能選項
● 在2D或3D畫面空白處單擊鼠標右鍵也可以彈出更多的操作功能選項，如複制與粘貼、重複與撤消、由3D輸出的新舊視圖切換、編輯2D圖塊等
STEP文檔輸入的改善:
● 新增了讀取文檔時的選項
● 更好的錯誤分析能力
我們建議您通過“cfg”指令或菜單“工具—系統設置”來對“鼠標右鍵設置”和“顯示光標坐標值”兩項新功能進行個性化設定，新版本VariCAD可以將單擊鼠標右鍵的響應進行多種設置，從而更加方便您的操作，這也是本次升級的最明顯特征之一
VariCAD 2011 is a 3D/2D CAD system for mechanical engineering. In addition to standard tools for 3D modeling and 2D drafting, the CAD system provides 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. 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.
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.
