We just uploaded a new web version of PadCAD with the bug fixes that are going to be in the latest iPad version (Version 1.5.1). I also added an Import button. You can now work on your padcad drawings if you have copied your padcad files to your PC or Mac. Simply go https://plugworks.com. Once PadCAD loads, click on the preferences icon. The panel will have a new button called "IMPORT". Click on it and you'll be prompted with a file browser. Choose your padcad file and it'll load your drawing.
Hope this helps in the interim while the new version of PacCAD gets approved by Apple.
