Yes, there is the web viewer . But it does require you have sufficient access to a web-site to install.

For instance a quick mock-up. IFRAME implementation at the bottom of the page. The 2D plan is exported from the plan view in SVG (and slightly edited). Full-screen there as well on this link. NOTE that in the text there are also instructions in Scandinavian - most important SPACE changes between Aerial and Virtual, Right-click lets you choose level.
