Here's some very preliminary coding for a single cycle just to see if this kind of animation would suit your purpose. Here is a video clip in case anyone else is interested in this type of thing ...[flash=400,300:1x2no254]http://www.youtube.com/v/5Y4RFyNm5Vo[/flash:1x2no254] and screenshots of web dialog at different stages. [image: bKiK_sheetCuts6.jpg] Please note: The coding is for PCs only. Unzip the .rb file and folder to Sketchup plugins subdirectory and open sheetCuts from plugin menu. This is not a traditional rectangle optimisation tool (although it could have one) but a device to produce: ... instructions for automated or attended machines ... animation for checking handling, sequence, timing and so on ... various preferences, details, analyses and other options (nothing compiled yet) Click on underlined words to select offset percentage or dimension, trim or cut, and to set rotate and settings. The number of cuts is calculated automatically. The final offcut is shown. Inputting a new number of cuts overwrites the automated calculation. I think this satisfies your PM request? Prev and Next will later be available to review and edit. I think this will be useful as a device for designing plywood or MDF furniture and sheet metal panels and so on. If you can find a use for it for your paper cutting problem, all well and good, but it will take a little time before it is really functional. Chris sheetCuts.zip
