The Insert a Hatch Pattern by Selecting the Boundary tool allows you to select an entity that has been drawn on the page (a ‘closed polyline’, ‘rectangle’, ‘circle’ or other closed entity on the drawing) as the bounding edge for the section pattern. The bounding entity must be one contiguous line, or each line segment must be connected end to end. Boundary lines must not be crossing. The pattern is selected, and the scale and rotation set and then a line of the bounding entity (e.g., circle) is selected by clicking. Once the entity to be filled has been highlighted, right‐clicking will fill the area in with the selected pattern.
