In drawings, you can have multiple embedded views on a drawing sheet that are at different model scales (e.g. 1/4" = 1' and 1/8" = 1'). You can add graphics to the views and treat them as if they were actual model graphics. Use the Scaled Sketching command to draw all graphics at a consistent scale factor. The scale factor used is based on a user-selected SmartFrame.
