Limitations of Using Edge Geometry
When you use the new tools for offsetting or projecting an edge the following functionality is not supported.
• Projecting an axis.
• Projecting or offsetting in trajectory based tools such as Blend or a Pattern of the type Curve.
• Converting the new offset geometry to Tapered.
The Project and Offset tools sometimes create composite curves from the projected and offset geometry. Some types of dimensions and constraints cannot be created to composite curves. To create a dimension or constraint to a component of the composite curve, you can create additional references to the geometry from which the composite curve was created.
