Now we'll explore graphic overrides to develop a sophisticated visual hierarchy that clearly distinguishes existing-to-remain elements from existing-to-be-demolished elements. This is crucial for creating professional demolition drawings that communicate design intent without ambiguity. Navigate to the Manage tab, select Phases, then Graphic Overrides. Our focus will be on fine-tuning the Existing and Demolished phase settings to achieve maximum clarity.
The existing cut lines deserve particular attention since they have the most significant visual impact in plan and section views—these represent walls being cut through in your drawings. Currently, the settings show color 127 (a professional gray tone) with a line weight of 3, which provides a solid foundation. However, the pattern is set to Hidden, which undermines the visual hierarchy we're trying to establish.
Let's optimize this by changing the pattern to a solid fill using the same 127 color. You'll notice Autodesk defaults to color 128, but maintaining color consistency is critical—even slight variations create unwanted outlines that compromise drawing quality. This adjustment immediately enhances the visibility of existing-to-remain elements, creating the professional clarity that clients and contractors expect from architectural documentation.
The persistent challenge with Revit's default demolition graphics is that demolished elements rarely stand out sufficiently. This is easily remedied through strategic line weight adjustments. Return to Phases > Graphic Overrides and locate the Demolished cut lines, currently set to weight 3. Incrementally increase this to 4, then 5, testing the visual impact at each stage. This iterative approach ensures you achieve optimal contrast without overwhelming the drawing composition.
Once you've established your preferred graphic standards, save these settings in your project template to maintain consistency across all future projects—this is essential for developing a recognizable office standard and improving workflow efficiency.
With our graphic overrides configured, we can now address how floor slabs appear in demolition plans. The challenge here is subtle: demolished floor elements often display as barely perceptible dashed lines that fail to communicate demolition intent effectively. This is where strategic graphic overrides prove invaluable, even if they require stepping outside Revit's default behavior.
Select the floor element requiring demolition graphics, right-click, and choose Override Graphics in View. Set this to By Element for precise control, then activate a surface pattern—diagonal crosshatch patterns work exceptionally well for demolition documentation. Apply this in black for maximum contrast. The result is an unmistakably clear demolition indicator that will translate well to both digital and printed drawings. Complement this with a comprehensive legend that eliminates any potential for misinterpretation.
Apply this same methodology to roof elements and any other horizontal surfaces requiring demolition notation. While you can make these adjustments directly within individual floor plan views, working directly on sheets often provides better context for overall drawing composition. Simply double-click to activate the viewport, implement your changes, then double-click outside to deactivate—maintaining this organized workflow prevents confusion and ensures consistency across your drawing set.
With these graphic standards established, the final step involves creating a professional legend system that clearly communicates your demolition notation to all project stakeholders. This documentation standard becomes the foundation for clear, unambiguous construction drawings.
