Hi, If your bounding box follows a right-hand rule or left-hand rule you could Buffer it with one side only. If not, Buffer with sides only, run through a PolygonBuilder/DonutBuilder, and then take the feature that is a hole as your new bounding box. I've attached an example of this.
If you don't like the rounding that the Bufferer does on internal angles, another option would be - use a BoundsExtractor - calculate a width and a height using ExpressionEvaluators - run your Scaler - do another BoundsExtractor - calculate the new width and height - calulate the difference between the two heights / 2 and the difference between the two widths - use these differences as parameters to an Offsetter Jason -----Original Message----- From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of waberskidarrow Sent: Friday, February 10, 2006 14:26 To: [email protected] Subject: [fme] Clipping contours I am generating contours using the surface modeler but along the boundaries the contouring is giving me zingers, mostly straight lines right along the boundary. To clean it up I created a bounding box then scaled it slightly ( I assumed it would scale about the middle of the box) but I did not get the results I wanted. I would like to offset the box say 5 meters inward then use it to clip the contours. Any suggestions? What about if I want to clip them in 3d? (Take the box drape it onto the contours then use it to clip the contours?)
