3D design application auto*des*sys form*Z is to be upgraded to version 4.0 - and the company says it will be taking the modelling tool in new directions. The upgrade details - reported in the company's in*form*Z newsletter - reveal that version 4.0 will sport a "modular structure and will open its architecture to plug-ins" - a move welcomed by users. Auto*des*sys says the development will lead to targetted, niche versions of form*Z. The company says it expects the first batch of specialized versions to focus on the architecture and product-design markets. The company says the upgrade will include targetted features aimed at niche markets, but refused to give details of a launch date.
