With GrafiCalc Extended 2010 users capture the functional intents of any mechanical design challenge by associating geometry, dimensions, and "smart" calculations in a single flexible model. Initial geometry can be sketched directly in GrafiCalc or easily imported from any popular CAD application using the 2-way DXF translator built within GrafiCalc. Then users can substitute parameters in the flexible model to ask and receive interactive decision support information and solutions.
