Graph
Graph Presentations Drawer. Allows data to be displayed in 12 types of 2D/3D graphs. i.e. line, pie, 2d/3d bar ……The graphs can be easily manipulated in different presentation formats (titles,legends,axis, background etc. can all be manipulated), 3D graphs can be rotated, graphs can be printed, copied to other programs (through the Windows clipboard). Statisitics of the graphs be be easily displayed (max., min, regression lines etc..), data can entered manually or through a text file or through the Windows Clipboard or generated using Graphs equations (see Below) or Excel. The data of the graphs can be saved.
ChemDesigner - Drawing
Chemical display/drawing package. Enables drawing of chemical compounds. Contains over 60 predrawn structures & symbols. Files can be saved and printed out.
Prosim – Simulator
Prosim is a customizable process design package. Which allows the user to design a process simulation situation. It currently incorporates 5 process items which controls can be manipulated through the effect of other items. Designs can be saved, edited, printed, process results can be saved as the process is running.
