I am using CAD2008. I have created a simple polygon with polyline then applied a spline to it. When I try and hatch the splined-polyline the hatch only works on part of the polygon and it doesn't seem to matter what shape. It seems to want to hatch on the outer boundary but doesn't want to fill the shape. I can copy the shape into a new file and it hatches just fine. Is there some variable that may need to turn on?
