Thomas, If you want to set a value once so that it can be used repeatedly through the svg, for example if you want a large number of circles the same radius and you want to be able to change that radius by editing a single figure, you could define the circle once and repeat it with the <use ... /> element, or you could define the radius in a CSS class and make all the circles members of the class. But I don't think that is what you want to do. By 'free settable number' I think you mean a 'variable'. Unfortunately you cannot have variables in SVG (or XML generally, for that matter). However, you can modify the SVG using Javascript. You could build a script into the SVG file that will calculate a radius and apply it to whichever elements you want. This is quite a big step up from plain SVG. ------------------------------------ ----- To unsubscribe send a message to: [EMAIL PROTECTED] -or- visit http://groups.yahoo.com/group/svg-developers and click "edit my membership" ----Yahoo!
