Wall Cleanups and Priorities Walls with multiple components clean up based on the priority assigned to each component and the location of each component within the wall. Matching component edges with the same priority are extended or trimmed to their intersection points. Components with a higher priority (a low priority number) cut through components with a lower priority (a high priority number). Wall cleanup priorities To identify the default cleanup priorities for the components used in the sample wall styles provided with AutoCAD Architecture, see "Default Cleanup Priorities of Wall Components" on page 726. The software calculates and performs wall cleanups in the following sequence: 1 Component information is gathered from the wall graph: ■ Endcaps are calculated. Endcaps that do not fit in the section may also produce a defect marker. ■ Sides of components are combined with endcaps to produce a component profile (like a 2-dimensional region). ■ When this profile is self-intersecting, the red defect marker is displayed. 2 Adjacent higher priority components are gathered from the wall graph from neighboring wall segments. 3 Higher-priority component profiles are subtracted from the lower-priority component profiles. 4 Doors, windows, openings, and interferences are cut and/or applied. 5 Shrinkwrap may be calculated and hatching applied. A failed shrinkwrap calculation may also result in the defect marker. 6 Graphics are drawn to an output device (for example, the AutoCAD screen, Object Viewer, Osnap stream, explode stream, and a plotter). 7 Solutions are cached for subsequent draw requests until the wall is modified again. Guidelines for Successful Wall Cleanup Red circles that appear in a drawing when using wall cleanups are defect symbols that indicate that cleanup settings or placement of a wall segment are preventing correct cleanup. Here are some recommendations for actions you can take to achieve successful wall cleanup: ■ Review the wall cleanup radius settings for each wall segment. A good starting point is to set the wall cleanup radius equal to half of the wall width. However, this may not apply to every situation and you may need to adjust the value to achieve the desired effect. NOTE A wall segment must be longer than its cleanup radius. ■ Use a smaller cleanup radius. A small cleanup radius also makes the graph display more readable. The length of the cleanup circle radius should be a value that is between one-half the wall width and the wall width. ■ Look for very short wall segments. You can find these short segments by turning on the Graph display representation. You can fix them by adjusting the baselines or by increasing the cleanup radius. Wall Cleanups and Priorities | 689
