The complete rigid frame displays in your drawing. Creating Custom Shapes for Structural Members If you want to design a member with one or more shapes that are not available from the Structural Member Catalog and cannot be created using the Structural Member Style Wizard, you can use the Style Manager to create custom shapes. When you create a custom shape, you can define three separate geometries (Low Detail, Medium Detail, and High Detail) to accommodate the different levels of detail in different display representations (for example, Plan Low Detail, Plan, and Plan High Detail). The geometries for the new shape can be set entirely from linework in the drawing area, or you can use an existing custom shape definition as a template and edit it to redefine any of its geometries. Hollow core concrete plank display representations example Once you have created a custom shape, it is added to the list of Structural Member Shape Definitions in the Style Manager. You can then create a new style from the shape, or you can assign the shape to an existing structural member style by adding it as a component in the design rules of the style. You can also edit, copy, paste, and purge shape definitions just as you can other styles. For more information on these operations, see "Style Manager" on page 489. Creating a Custom Shape for a Structural Member Use this procedure to create a custom shape for a structural member based on linework you have drawn or otherwise inserted in the drawing area. 1 In the drawing area, create three geometries to define the Plan Low Detail, Plan, and Plan High Detail display representations of the shape. You can draw entirely new geometries, or you can insert geometries from existing shape definitions (see "Inserting a Custom Shape in a Drawing" on page 1449.) For Plan Low Detail, you can use lines, arcs, circles, or polylines. For Plan and Plan High Detail, use closed polylines, splines, ellipses, or circles. Note that these entities must not intersect. 2 On the Format menu, click Structural Members ➤ Member Shapes.
