GrafiCalc 2009 specifications

GrafiCalc 2009 offers a collection of facilities that have been continuously enhanced over several years to incorporate latest computing technology and valuable inputs from users.

Following are GrafiCalc specifications:

User sensitive features

Sketching tools

Constraint manager: GrafiCalc includes an ultra-fast constraint manager especially tailored for function modeling. The powerful point and click constraint manager can resolve virtually unlimited number of circularities. It tracks original design intents to automatically resolve plural solutions. Initial geometry can be entered within GrafiCalc as well as imported from any DXF compliant CAD software using the built-in 2-way automatic translator.

Geometry definition tools: Line, Circle, Arc, Poly Line, Closed Boundary. Initial geometry can also be imported from any DXF compliant CAD software.

Constraint tools: Free point, Concentric, Centroid, Endpoint, Proportional, Tangent, Intersection, Virtual Intersection, On-Entity/Slider, Parallel, Perpendicular, and at a fixed angle with respect to another line.

Automatic Constraint inferring facility: GrafiCalc 2006 includes an automatic constraint inference facility which, when turned on, allows you to snap automatically to center, endpoints, tangents, centroid, and on-geometry automatically. Lines snap automatically to horizontal and vertical.

Text tool: Allows entering notes and annotations. Use all available fonts in your computer.

View manipulation tools: Pan, Zoom, Zoom by 2X, Zoom by .5X, Zoom to fit, Show paper boundary.

Automatic measurements

GrafiCalc incorporates linear, radial, and angular dimensions that can be constrained to measure any aspect of the flexible model. The measurements are updated automatically as design intents are altered. The measurements can be directly included in calculations setup in GrafiCalc Formula bar.

Calculations facilities

Formula Bar: GrafiCalc incorporates a conventional spreadsheet type Formula bar that is used to establish bi-directional association between geometry, dimension, values, and calculations.

Programmable geometrical calculators: GrafiCalc includes a programmable calculation facility that enables users to setup multi-line x = f(y) type of calculations. Dimensions and geometrical values can be directly incorporated in the calculation statements that are checked for unit integrity on a line by line-by-line basis. If and Else statements are supported. Multiple calculations can be combined. Results are used for developing calculation driven geometry. Calculation statements and answers can be copied into the Windows clipboard for pasting into technical reports.

Built-in calculation functions: GrafiCalc includes a library of 88 built-in functions to setup in the Formula bar and the Programmable calculator. Complete built-in function listing is available at the end of this page.

Automatic backsolving (Goal Seek)

GrafiCalc allows users to stipulated any measured or calculated value as design target and then have the computer Goal Seek the characteristics of any geometry that participates in the result until the actual value of the measurement or the calculated value is equal to the stipulated target value.
