Surface Explorer 3D plots mathematical surfaces in 3D. User defined surface equations can be explicit, implicit, or parametric. Surface and color equations are specified by user. Can export to clipboard, VRML, POV, DXF, printer. C++ source code included. Freeware.

Sheet Lightning is a specialised engineering 2D/3D CAD System for creating and unfolding sheet metal designs for fabrication or manufacture. It handles everything from simple cylinders, cones, rectangular ducts and ovals, to adapters, adapting any of these section types, interections and multi-intersections between of any of these types to any level of complexity.

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.

MadCalc is a full featured graphing calculator application for your PC running Windows. With MadCalc you can graph rectangular, parametric, and polar equations. Plot multiple equations at once. Change the colors of graphs and the background. Use the immediate window feature to evaluate complex multivariate expressions.

Plotting functions (usual and parametric) with more possibilities.
Differentiation of any order (with simplification). Construction of tangents to the graph. The simple and clear interface with detailed documentation and examples of work.

FindGraph is comprehensive, feature-rich graph editor, as well as a curve fitting and digitizing tool for engineers, scientists and graduate students. Convert plots back to X,Y data from any published report for later processing and manipulations. The program offers 12 generic fits, including Linear Regression, Logistic Functions, Fourier approximation, Neural Networks, B-splines curves, plus a library of over 300 industry-specific formulas.

Dexterpen is a stand-alone Windows graphics utility for those small repetitive tasks which take away valuable time from your working day. Use Dexterpen to create collections of drawings of slightly different components to import into your favorite CAD program, or as an EMF into WORD.
You can also use Dexterpen to dynamically experiment with components without learning to learn program or buy an expensive parametric design program.

If you have read about explicit, geometry-based 3D CAD, you know it is the best approach for creating flexible, lightweight designs. Now, PTC brings you a free download from the CoCreate product family - CoCreate Modeling Personal Edition, a 3D CAD system you can use for assemblies with up to 60 parts. Download a FREE version of CoCreate Modeling Personal Edition today and see how liberating an explicit, geometry-based 3D CAD system can be.

Parametric driven design, change the dimension, change your design. Can your AutoCAD do like this? AutoPara, a powerful parametric engine for AutoCAD, make you more productive.

Powerful but easy-to-use graphing, curve fitting and calculating software. Graphs Cartesian, polar and parametric functions, graphs of tables, implicit functions, inequalities and slope fields. Up to 100 graphs in one window. Calculus features: regression analysis, intersections, derivatives, tangents, normals and more. The program has printing capabilities, multi-document interface, customizable toolbars.
