The older releases of the browser Internet Explorer of Microsoft did not support the rendering of SVG. This changed with the new releases of the browser. The tools for Cone Strike-out and the Tubesheet Layout have the possibility to generate an image (.PNG) of a vector drawing (.SVG). Internet Explorer required a plugin from Adobe to view this SVG drawing. With the new releases of Explorer the plugin is not required anymore. The tools have been updated to reflect that change and allow Explorer to render the SVG with its build-in renderer.
