| Geometric figures can be defined by either symbolic constraints or numeric locations. Measurements on your drawing are not only presented numerically, but also expressed symbolically as mathematical expressions that can be sent to Mathematica via MathLink for analysis. Where Mathematica can be used to automate the analysis of mathematical expressions, Geometry Expressions automates the creation of symbolic expressions in the geometry arena. Key Features

														 The package comes with electronic documentation in both PDF and Mathematica Help Browser formats. About the DeveloperSaltire Software was founded in 1989 as a spin-off from Tektronix Computer Research Lab. Its award-winning Analytix product line features constraint-based mechanism design, synthesis, and analysis. Saltire has since developed mathematical software for leading calculator companies, and a category-leading optimization package for the floor-covering industry. Geometry Expressions is developed and supported by Saltire Software.
