Part 5 -- Colors and Shadowcasting

1. For a more realistic view, get the Eye tool and drag down and to the right to look at the front facade of the building.


2. From this vantage point a more likely color can be chosen for the walls of the cottage. Select everything but the roofs by getting the arrow tool and dragging a selection rectangle across the lower half of the building. (Because of the likelihood that objects will extend beyond the viewing window in 3D, a selection rectangle in DesignWorkshop selects any object inside it or crossing it.) When the correct objects are selected, double-click on the color indicator icon in the tool palette to open the color picker. Pick a bright yellow color (from near the center of the picker wheel, so it's not too saturated).


When you click OK, this new color will be assigned to the selected objects, and will become the current color, used for any new objects you draw.


That completes the creation of the massing model of a simple cottage! To complete this section of the tutorial, pull down the View menu and give the Shadow Casting command.


3. Depending on the relative speed of your Macintosh, it may take up to the better part of a minute to finish the initial shadow calculation. When that's done, get the Eye tool and move in increments all the way around the model.



Notice how much more quickly the model redraws, yet observe the shadows visible all around, even on the back wall of the cottage. This is because shadows in DesignWorkshop are calculated as 3D objects in the model space, not just as a screen bitmap, so after the initial calculation the shadows are valid for any view of the model, until the sun time or the model geometry is changed.


4. You now have the basics for building solid models in DesignWorkshop. Be sure to save your work, and it take a quick break before going on to the next section.

In the next section of the DesignWorkshop tutorial, you'll learn how to quickly turn the massing model into a full spatial model with an interior, solid walls, and door and window openings.
