I have images for parts of a building I need to create AutoCAD entities from. The issue is that the image doesn't have usable control points past 3/4 of the image. There is info however, that I need to transfer on the remaining 1/4 of the image. When I use rubber sheet to take the scanned image that has much skewing to it, the control points seem to create a mask that erases everything outside of the control point area. Would there be a way to fix this?
