Before BikeCAD starts, you'll be asked if you want to trust the signed applet distributed by "Brent Curry". Click "Yes". Otherwise, you will still be able to use the applet, but you will not be able to save and retrieve your designs. Have fun! For those that require the added functions of BikeCAD Pro, it is now available. Check out this sample output from BikeCAD Pro: SampleCSV.csv, SampleDXF.dxf, SampleSVG.svg. If BikeCAD does not launch, you may need to download the latest Java plug-in here. To view SVG files from BikeCAD Pro, you will require an SVG viewer available from http://www.adobe.com/svg.
