DiamCalc 3.2 Beta & DiamCalc 3.2 Pro

January 2, 2009

What is new in the DiamCalc 3.2 ?

For several years the diamond industry has designed most of its new diamond cuts using various computer aided design software like GemCad. The virtual models of potential new diamond cuts are then transferred into DiamCalc software. Designers check the appearance and light performance with DiamCalc photo-realistic images and virtual cut assessment tools like Hearts and Arrows viewers, ASET and Ideal-Scope. By trial and error designers then optimize the proportions. OctoNus’s new DiamCalc 3.0 vastly improves this process...

Important! Please read this before download DiamCalc

1. The installation programs are digitally signed. Once you downloaded *.exe please check the signature

We do not recommend to run installation if the signature is absent or not valid: this is dangerous (running corrupted file can lead to unpredictable results)! Click here to read how to check the signature. If the signature of installation file is not OK or absent please retry to download again. You can also try to use a different download server.
If the problem persists please send message to DiamCalc support service.

2. Test you GPU (Graphics hardware) with DiamCalc Graphics Compatibility Evaluator utility

The utility will attempt to render a reference data set in order to chek if your Graphics hardware is compatible with new OctoNus HDR rendering engine. Please notice: even if you get negative test result the non-HDR rendering still available in DiamCalc3. Most of existing windows computers are compatible with non-HDR OctoNus rendering engine.

Important! If you get the expiration message from DiamCalc 3:

Attention for DiamCalc3 users: If your DiamCalc gives the message "The software has expired..." there are several option to fix the problem:

1) Owners of short keys only - you can install and use the new version DC 3.2 beta

2) Owners of short keys and long keys - you can download and install the updated DiamCalc 3.0 installation packages in the section DiamCalc 3.0 (select your type of hasp keys and press button Download Now). Necessary dll files will be updated.

3) Manual update - download this update DC3CutDesignerUpdate.zip (558 Kb). This package has 3 dll files, you should unpack it and copy in your working DiamCalc folder (usually C:\Program Files\OctoNus Software\Diamond Calculator****). Say yes to overwrite the existing CutDesigner.dll and GingemaUser.dll. Please be sure to exit from any running DiamCalcs while updating the files.

We strongly appologize for this inconvenience.
