Gem Cut Studio Version 1.1
The new and improved version of this versatile and dynamic gemstone design and optimisation software is now available for download here: - https://gemcutstudio.com/download
Available free to existing users and as a 30 day free trial. No vested interest but I recommend this. For GemCad users it takes some getting used to but, based on personal experience, is easier to get to grips with.
Here is the design shown above as resequenced, annotated and 'cut' in GCS and the resulting facet diagram.
