Does anyone know how to create a sketch datum on the fly (in Wildfire) while creating a new feature (such as a curve)such that the sketch datum is embedded in the new feature? In other words, so the sketch datum doeasn't show up in the model as a new feature. I am trying to create a sketched curve on a plane that is offset from an existing plane, but I can only seem to make the curve along with a new datum (two features). In 2001 making a sketch datum on the fly as part of the feature creation would only result in one new feature (the curve) being created. Thanks, Mark
