If you are having problems with solar analysis and that all too familiar "solar analysis has expired..." message then you can access the latest update HERE.
You will now notice, when you click on the lighting tool, the drop down for 'New' no longer displays. Instead, the lighting icon is now a single button that will open a dialog to start a new analysis.
In the 'Lighting Analysis in the Cloud' dialog, the bottom left will indicate a version number. As of today, it should say v22.214.171.124.
Stephanie Egger who writes blogs at Insight 360 has written two posts that go through step by step using the new tools. Visit http://blogs.autodesk.com/insight360/ to read the latest.
