The calculation is intended for the purposes of geometric and strength designs of spiral cylindrical torsion springs made of wires and rods in circular sections, loaded with a static or cyclic loading. Application is developed in MS Excel, is multi-language and supports Imperial and Metric units. Is based on ANSI, ISO and DIN standards and support many 2D and 3D CAD systems.

Geometric design and strength check of spur gear with straight and helical toothing. Application is developed in MS Excel, is multi-language and supports Imperial and Metric units. Is based on ANSI/AGMA and ISO/DIN standards and support many 2D and 3D CAD systems (AutoCAD, AutoCAD LT, IntelliCAD, Ashlar Graphite, TurboCAD, Autodesk Inventor, SolidWorks, SolidEdge, Pro/E).

PDSYMS v2.0 is an Architectural/Interiors DWG-FORMAT Symbols Library Add-on for all CADD packages running on all platforms and Operating Systems.

With this AutoCAD add-on you can create mathematical curves. Curves can be defined as explicit, parametric or polar functions. Function's formula can also be changed dynamically by changing parameter 'p' value(parametric modeling). Use standard AutoCAD commands(revolve, extrude, ...) to create solids and surfaces from these mathematical functions.

AutoDWG Attribute Extractor Help you batch extract attribute data from AutoCAD attribute blocks without need of AutoCAD. It supports most DWG formats including AutoCAD Release 9 through to the present AutoCAD 2002.

OBJ2CAD 2010 - Import OBJ is an AutoCAD 2010 application to import OBJ files (Wavefront) into AutoCAD drawing. It can import OBJ file and create lines, points, faces, polyface mesh and 3d solid drawing entities. Using it with OBJ4CAD 2010 add-on it is possible to convert any 3d entity into 3d solid object.
