VariCAD 是 3D/2D CAD 软件，主要用于机械工程设计。全面的 CAD 软件使设计人员能够快速创建、评估和修改他们的模型。该软件作为一个“满载”软件包出售，具有所有特性和功能，价格非常实惠。VariCAD 提供卓越的性价比，使其成为当今市场上最明智的选择之一。

用户界面和系统环境
VariCAD 的图形用户界面 (GUI) 旨在实现快速直观的 3D/2D 定位。它经过精心定制和调整，以反映设计师的思维过程，因此可以通过最少的步骤来捕捉和传达想法。所有命令的创建都着眼于易用性。

您可以从创建 3D 模型开始，然后使用它自动创建图纸文件，或者您可以仅在 2D 中进行绘制。3D 设计通常更“自然”，因为它紧密地代表了实际的零件和组件。3D 方法通常比 2D 绘图更直观。在 3D 中创建的模型可以轻松转换为传统的 2D 文档。VariCAD 提供了在 3D 模型更改后进行 2D 更新的工具。

3D 建模
VariCAD 提供了一个基本 3D 形状（如盒子、圆柱、圆锥等）的库，可以通过编辑它们的尺寸轻松修改。实体也可以通过轮廓旋转、挤压或放样来创建。更复杂的工具包括两个轮廓之间的旋转混合、圆形和矩形之间或不同轮廓之间的放样以及螺旋曲面的创建。

可以添加或减去实体，从而形成代表真实机械零件的布尔树。布尔运算具有自动修剪选项（所谓的选择性布尔运算）。也可以使用预定义的操作，例如钻孔、面铣或槽铣。边缘可以是圆形的或倒角的。VariCAD 提供了很多实体转换或编辑的可能性。此外，您可以轻松编辑布尔树 – 从 3D 中选择实体零件，或从显示结构的列表中选择它们。

参数和几何约束
虽然您可以轻松地变换实体或其零件，但您可以选择定义几何约束。定义后，约束允许您在定义的位置“粘贴”对象。更准确地说，您可以移除受约束对象的自由度。如果其他对象发生更改或变换，受约束的对象会自动更改其位置。例如，如果您将凹槽约束到轴的末端并且轴的长度发生变化，则凹槽与末端边缘的距离保持不变。可以在实体元素之间、整个实体之间或在创建实体的 2D 轮廓内（例如，通过挤压）定义约束。

每当您输入实体尺寸、约束距离或用于实体创建的二维轮廓尺寸时，您都可以选择使用参数甚至包含参数的数学表达式。更改参数值，您可以更改实体的形状或位置。

3D 装配和组
VariCAD 还提供装配支持工具。如果定义了零件和装配体之间的链接，则对零件文件所做的任何更改都会反映在装配体文件中，反之亦然。也可以定义实体的链接副本（所谓的相同实体）。在这种情况下，编辑一个对象会导致更新其所有相同的副本。也可以定义实体组，使多个对象的选择和可见性更改变得简单。
碰撞测试（干扰）

3D 建模的一项出色功能是组件干涉检查。VariCAD 可以检查 3D 装配体是否存在组件之间可能的碰撞（重叠体积）。

计算
VariCAD 可以计算二维截面面积、表面积、体积、质量、重心和转动惯量。还包括机械零件计算 – 机械设计师每天使用的标准零件。有拉伸和压缩弹簧、预应力螺栓连接、销和平行键、槽轴、轴承、组合应力下的梁（弯曲和扭转）、正齿轮和锥齿轮几何形状以及皮带传动的计算。
表面发展（钣金抗弯）

VariCAD 还可以创建 3D 实体或钣金零件的开发（未弯曲）表面。开发表面的 XY 坐标可以保存到文本文件中以供进一步处理。您可以输入弯曲系数以自定义您的计算，以反映材料和技术。
机械零件和符号库 VariCAD 包含标准机械零件（ANSI、DIN）库，例如螺栓、螺母、销、插头、开口销、垫圈、轴承、轧制和拉制形状以及液压、气动和电气符号。

3D – 2D 导出
3D 模型可轻松转换为 2D 工程图，以生成传统的绘图文档。您可以通过定义 3D 视图来创建一个或多个选定实体的 2D 视图。此外，您还可以导出指定的部分。VariCAD 支持在 3D 更改后更新 2D 工程图。

2D 绘图和编辑
绘图功能经过优化，易于在工程中使用。2D 绘图的一些方便功能包括：对象和捕捉点的自动检测、多种捕捉模式、辅助构造线、正交模式、矩形网格、绘图层、块创建、自动边框检测的阴影线、高级尺寸标注、完成符号、焊接符号、公差符号等等。您可以以毫米或英寸为单位进行绘制。

BOM 和标题块
VariCAD 提供了用于维护产品数据结构的工具。零件的属性和标题栏的内容之间存在联系。您可以从装配创建物料清单 (BOM)，或使用批量属性更改、信息排序等命令轻松修改数据库。每个零件都可以包含属性，如名称、材料类型或供应商。此类数据可用于物料申请、物料清单 (BOM) 的创建、标题栏的填充或其他目的。

产品的数据结构 (BOM) 可以导出到其他系统或电子表格中。掩码用于 BOM 定制；您可以完全根据您的需要对其进行修改。掩码定义了实体或装配属性的使用，使用标题栏，从 BOM 导出数据的方法等……

兼容性
VariCAD 可以与其他 CAD 系统交换文件。您可以导出 STEP (3D)、STL (3D)、IGES (3D)、DWG (2D)、DXF (2D) 文件，以及导入 STEP (3D)、DWG (2D)、DXF (2D) 文件。文件可以单独转换或批量转换，从而一步转换多个文件。

File size: 138 MB
VariCAD is 3D / 2D CAD software primarily intended for mechanical engineering design. The comprehensive CAD software enables designers to quickly create, evaluate, and modify their models. 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. It has been carefully tailored and tuned 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.

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. VariCAD provides tools for 2D updates after changes of 3D models.

3D Modeling
VariCAD provides a library of basic 3D shapes (like a box, cylinder, cone, etc.), which are easily modified by editing their dimensions. Solids can be created also by profile rotation, extrusion, or lofting. More complex tools include rotation blending between two profiles, lofting between a circle and rectangle or between different profiles, and creation of helical surfaces.

Solids can be added or subtracted, thus forming Boolean trees representing real mechanical parts. Boolean operations have options of automatic trimming (so called selective Boolean operations). Predefined operations like drilling of holes, face milling or groove milling are also available. Edges can be rounded or chamfered. VariCAD provides a lot of possibilities of solid transformations or their editing. Also, you can easily edit Boolean trees – either selecting solid parts from 3D, or selecting them from a list displaying structure.

Parameters and Geometrical Constraints
Although you can comfortably transform solids or their parts, you can optionally define geometrical constraints. Once defined, constraints allow you “to stick” object at defined location. More exactly, you can remove degrees of freedom of constrained objects. If other objects are changed or transformed, constrained object changes its position automatically. For instance, if you constrain a groove to the end of a shaft and the shaft length is changed, the groove remains in constant distance from the end edge. Constraints can be defined among elements of a solid, among entire solids or within a 2D profile creating a solid (for instance, by extrusion).

Whenever you enter a dimension of solid, a distance in constraint or dimension in 2D profile used for solid creation, you can optionally use parameter or even a mathematical expression containing parameters. Changing parameter values, you can change shapes or locations of solids.

3D Assemblies and Groups
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 of solids can also be defined (so called identical solids). In such case, editing of one object causes update of all its identical copies. 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 inertia. Mechanical parts calculations are also included – for standard parts used every day by mechanical designers. There are calculations of 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 (unbent) surfaces of 3D solids or sheet metal parts. The XY coordinates of developed surfaces can be saved into a text file for further processing. You can input bending coefficients in order to customize your calculations, to reflect material and technology.
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 electrical symbols.

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 optimized for easy use in engineering. Some handy features of 2D drawing include: automatic detection of objects and snap points, numerous snap modes, auxiliary construction lines, Ortho mode, rectangular grid, drawing layers, block creation, hatching with automatic border detection, advanced dimensioning, finish symbols, welding symbols, tolerance symbols, and many more. You can draw in millimeters or in inches.

BOM and Title Blocks
VariCAD provides tools for maintaining the data structure of the product. There are links between attributes of parts and content of title blocks. You can create a bill of material (BOM) from an assembly, or easily modify the database using commands like mass attribute changes, sorting of information, etc. Each part can contain attributes, like name, type of material or supplier. Such data can be used for material requisitions, creation of bills of materials (BOM), filling of title blocks, or other purposes.

The data structure of the product (BOM) can be exported into other systems or into a spreadsheet. A mask is used for BOM customization; you can modify it exactly according to your needs. Mask defines usage of solid or assembly attributes, working with title blocks, methods of data exports from BOM etc…

Compatibility
VariCAD can interchange files with other CAD systems. You can export STEP (3D), STL (3D), IGES (3D), DWG (2D), DXF (2D) files, and import STEP (3D), DWG (2D), DXF (2D). The files can be converted individually or in batch routines, thereby converting multiple files in one step.
