Basic operations may be invoked using icon menus, pull-down menus or commands entered on
the command line. Certain functions are called using the ctrl or function keys. It is
recommended to use the icon menus - they are grouped in columns to the right of drawing
area. You can also place the icons into individual boxes representing floating icon menus.
2D Drawing and Editing
Drawing functions are modified for use in engineering. While drawing, you can use:
intelligent cursor automatically detecting items and their important points, great amount
of snap modes, variability in item selection, cursor snapping, mesh of auxiliary
construction lines, ortho mode, rectangular mesh, maximum 250 layers, block creating,
hatching with automatic border detect, advanced dimensioning, surface texture symbols,
welding symbols, tolerance symbols and many other features. You can use milimeters as well
as inches in drawing.
Mechanical Part and Symbol Libraries
The system contains libraries of bolts, nuts, pins, plugs, cotters, gaskets, bearings,
rolled/drawn shapes a symbols for schemes - hydraulic and pneumatic systems and electro
systems. The user can add items to these libraries or modify dimensions of mechanical
Drawing Databases, BOM
The drawing database represents data structure of the product. You can create it manually,
using data extraction from the assembly drawing (by getting the block list or associated
items and their attributes), by loading a file from a directory or using a browser. There
are constraints between data in detail and assembly drawing title blocks and the assembly
database. You can build a bill of material (BOM) from the database. Also, you can modify
these databases, block attribute definitions and title block creating using
"masks". You can customize the system depending on your needs. The data
structure of the product (BOM) can be exported into other information systems or
Modeling includes basic creation of 3D solids using complete and incomplete rotation of
profile around the axis, extrusion of profile into space or blends from one profile to
another. 3D solids modeling tools include rotation blend between two profiles, blend
between a circle and rectangle and bolt surfaces. Also, the system offers a library of
basic 3D solids (prism, cylinder, cone and many others). You can modify the basic 3D
solids by editing original profile. If the 3D solids are created by inserting from
library, you can change their shape by editing the parameters. 3D solids can be added or
subtracted - thus forming Boolean trees. There is an option of adding 3D solids with
automatic trimming and subtracting 3D solids with automatic portions removal. In addition
to the common operations, the system provides predefined operations like hole drilling,
facet milling, groove milling and basic edge beveling/filleting. The Boolean trees created
are further editable.
To position 3D solids in space, there are multiple tools available including intelligent
cursor automatically detecting 3D solids and adjacent points. Model space view can be
exported anytime into 2D drawing space with hiding hidden edges. You can query collisions
in space, volume size, centroid coordinates, moment of gyration and 3D solid surface size.
You can define sections in solids. Such sections can be switched off or switched on
especially before exporting 3D scene into 2D drawings.
As far as the display control is concerned, you have multiple tools available - view
rotation, zoom, panning, saving and loading individual views, different display methods
(shading, no shading, etc.). You can use viewing using OpenGL. If your system supports
this technology, you are going to get a significant shading acceleration on a part in real
time with an option to rotate the view angle . The system internally works with solids
described by B-representation, but the user can access individual elements - that is an
analogy of accessing the Boolean tree.
Mechanical parts library is also available in 3D modeling. Parts inserted from library
into 3D space can be switched between work and precision alternatives at any time. Work
alternative saves CPU time significantly, while precision alternative displays shapes of
parts exactly (for example balls in bearing etc.) You can use also many tools of assembly
support. If connection between detail and assembly is defined, any changes in detail file
are created also in assembly file and vice versa. You can define identical copies in the
same file. Edit of one object is automatically mirrored onto other objects - members of
identical copies. Groups of solids can be also defined. Solids included in group can be
easily selected for each operation. System allows changes in groups displaying -
visibility changes, shading changes and detection changes.

LinuxCAD is today's leading computer aided design
and drafting program for The Linux Operating System.
LinuxCAD has grown in sales and functionality
since its original introduction in 1998.
LinuxCAD now represents a complete computer aided
design program for Linux ... it is a complete replacement for AutoCAD. For any practical
purpose, it implements all major features of AutoCAD in such a way that experienced
AutoCAD users do not need additional training to start working with LinuxCAD.
Linux users who are new to CAD will find our
Users Manual an easy way to learn the CAD trade. There is so much similarity between
LinuxCAD and AutoCAD, that while learning LinuxCAD, you will simultaneously learn AutoCAD.
With remarkable ease you will find yourself
creating all kinds of technical illustrations, diagrams, sketches and industrial quality
