VariCAD 2010.2.03 | 90.12 Mb
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 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, forstandard 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 titleblocks, 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.
