 Polygon Offset 1 Year, 4 Months ago Karma: 0 I have an excel 2010 spreadsheet which contains a list of 2D points (x,y). The points describe a polygon of (n) number of points. I would like to generate an offset polygon some distance away from the original polygon and graph both of the polygons. See the attached illustration. Thanks, Dave

 Re:Polygon Offset 1 Year, 4 Months ago Karma: 482 I can't think of a quick answer. It looks like you will have to tackle this problem using some custom VBA. ExcelCalcs could help you on a consultancy basis if you wish?

 Re:Polygon Offset 1 Year, 4 Months ago Karma: 0 Thanks for the offer John. I've already started the project and have made good progress toward a solution to a simple offset problem. My needs are not as complicated as driving a CNC machine. I'm just looking for the same type of routine that every CAD program can do. Just select a chained set of lines and offset it in one direction to create a parallel offset to describe a set of exterior walls for a building. I've searched the web for a standard routine that I could incorporate as a VBA add-in but haven't had any luck finding something easily incorporated into Excel. Thanks, Dave
