Autodesk DWF Writer

Autodesk DW Writer is a free program from Autodesk for secure exchange 2D and 3D data in DWF format. Allows the exchange of design data with a large territorial distribution of the team, ensuring efficiency collaboration. Among the main features of the program: tools for automatic publication of 2D and 3D files using output tools in DWF format, the ability to select the Autodesk DWF Writer module for SolidWorks 2006, CATIA V5 or Pro/ENGINEER Wildfire 2.0 to publish all design information from 3D models, the ability to publish from Microsoft applications.

Autodesk DWF Viewer

Autodesk® DWF™ Viewer is a small free application, which is used to exchange design data in electronic form. Designed specifically to work with DWF™ (Design Web Format™), the program allows you to view and print complex 2D and 3D drawings, maps and models.

DWG TrueView - dwg/dxf viewer from Autodesk

If one created a file, sooner or later the other will want to view or print this file.

It is clear that using the full-fledged application in which this file was created only for printing or viewing is not only inconvenient, but also expensive. Full-featured applications cost quite a lot of money...

So, free viewer dwg and dxf files from Autodesk - DWG TrueView

All it can do is show files of these types, display selected layers, print and publish their contents in dwf format. With such modest functionality, the DWG TrueView distribution weighs as much as 110 MB! Actually, the viewer itself takes up only ~300 kb. The rest of the volume will take full core AutoCAD for embedded solutions - Object DBX.

In other words, for all its shortcomings, DWG TrueView has one powerful advantage - it interprets dwg files and dxf through the AutoCAD core, which eliminates discrepancies when editing and viewing the same file.

The free SketchUp Viewer is designed to view and print models created in SketchUp. Because SketchUp Viewer does not include tools for editing the model, it is much easier to use for people who are not familiar with SketchUp. Additionally, models viewed in SketchUp Viewer are protected from inadvertent modification, ensuring that your customers see exactly what you intended to show them.

A program for calculating and constructing diagrams of bending moments, transverse and longitudinal forces, displacements and reactions of supports in beams, flat and spatial frames. The finite element method (FEM) is used for the solution. The FEA processor is integrated into AutoCAD using VBA. The AutoCAD environment itself is used as a pre- and post-processor. That is, drawing a model and specifying forces, moments, distributed loads, support elements, as well as presenting calculation results occurs using AutoCAD. To facilitate the installation of forces and supports in the frame model, a set of buttons (flyMenu) has been developed. The KarkasA program only works in AutoCAD 2006, 2007, 2008, 2009 32-bit versions. The program has not yet been adapted for the AutoCAD 2009 64-bit version.

ACEditor - external multiline text editor for AutoCAD (as well as all products based on the IntelliCAD core: BricsCAD, ZwCAD, etc.)

The "AKiR" program (Analysis of Kinematics and Performance) is designed to synthesize the kinematic diagram of flat lever mechanisms, both simple and complex mechanical systems. The main capabilities are performance analysis (mobility is equal to one), analysis of connecting rod curves of flat lever mechanisms, kinematic analysis (displacement, speed, acceleration of an arbitrary link), optimization of the mechanism diagram according to kinematic parameters.
The prototype was the TMM program (author S. Ruev).

Program OtkloneniiaRazmerov is intended to show the permissible deviations in the dimensions of parts in the hole system.

Tolerance fields are not all that are in GOST(e). But everyone is not needed, as the experience of working at the design and engineering institute of heavy engineering shows. The program is very simple and does not need any explanation. Enter the size, click the button for the corresponding tolerance field and read the value of the permissible deviation in the corresponding text box. Deviations correspond to GOST. The program was created in Visual Basic 6.

Cone Layout is a specialized program for creating the development of a truncated cone. It will be useful for welders, engineers, auto mechanics and anyone who works with metal cutting. For ease of use, the program displays a rotating three-dimensional model with dimensions.

The flat projection can be printed on a printer or plotter to be used as a template for cutting out shapes from metal plates. Or it is possible to export it to AutoCAD DXF format for use on CNC machines program controlled(CNC). Cone Layout can also save in Encapsulated PostScript (EPS) format or save coordinates in plain text format.

Thanks to the cost minimization function, the program optimizes the amount of material used, the seams along which cutting will take place, and the smallest piece of material on which the projection can be placed will be used to construct the development.

The program was originally developed to design a racing motorcycle exhaust pipe. Now it is used for completely different purposes: the creation of biomechanical manipulators, paper aircraft models, historical reenactors to create copies of medieval helmets, cone stands for jewelry displays, metal rockets, exhaust pipes for choppers and much more.

Key Features and Functions

  • optimization of material use;
  • support large quantity units of measurement: meters, inches, feet, yards, radians, degrees, grads, minutes, points;
  • export to AutoCAD DXF, Encapsulated PostScript EPS and TXT;
  • the ability to print large layouts on multiple pages;
  • detailed help system.
