If you want to give your drawings a sense of depth try using the Silhouette tool from the Graphic Display options dialogue box and apply a ‘’Silhouette Style’’ to the edges of your model elements. Revit has the ability to determine the silhouette for each specific view in your project - be it an elevation, section, perspective, etc.
Go to Graphic Display Options in the view settings. In the silhouettes menu, select a line with a sufficient thickness.
In the Graphic Display Options Dialogue box, select <Edit/New…>.
In the Line Styles Dialogue box create a new line style called Silhouette and give it a line weight of about 6 or 7.
In the Graphic Display Options Dialogue box, select Silhouette for the Silhouette style and then click apply. The outline of the building will now be bolder as shown in the second image below
View my previous blog on Anti-Aliasing for another tip on how to create sharper and more interesting 3D views. Using silhouette styles to enhance your drawings makes a big difference to the visual appeal- particularly in the case of perspective views. Try using different line types when applying silhouettes. In the Graphic Display Options dialogue box try experimenting with the shadow and background options to achieve some very dramatic affects.
