6. OrcaFlex OrcaFlex User Group, 2004 www.orcina.com Slide 6 of 8 - Recent Developments Model Building and Calculations Lines can be excluded from statics Unstable simulations can now be saved Connection arclengths can now be relative to End B. This applies to Line Attachments, Links, Winches and 6D Buoys. This is particularly useful with the new Line Length Wizard.
