Copyright Goodheart-Willcox Co., Inc. Chapter 17 Materials in AutoCAD 467 The properties in the Grout Appearance category control what the grout looks like. The grout is the line between the tiles. The Grout Color property is set to dark gray by default, but any color, image, or texture may be used. The Gap Width property deter- mines how wide the grout lines are in relation to the tiles. There are horizontal and vertical settings. In some cases, such as for a hardwood fl oor material, you will have to set the scale differently on the horizontal and vertical axes to make the gap thicker in one direction. The properties in the Stacking Layout category are only available for a custom pattern. The Line shift property changes the location of the vertical grout lines in every other row to create an alternate pattern of tiles. The default value is 0.50 and the range is from 0.00 to 100.00. The Random property randomly moves the same lines. This works nicely for hardwood fl oor materials. The default value is 0.00 and the range is 0.00 to 100.00. The properties in the Row Modify and Column Modify categories are available with all tile pattern types, but may be disabled by default. To enable the settings, pick the check box by the category name. The settings in these areas allow you to change the number of grout lines in the horizontal and vertical directions to create your own pattern. The two Every properties determine which rows and columns will be changed. When set to 0, no changes take place in the row or column. When set to 1, every row or column will be changed. When set to 2, every other row or column will be changed, and so on. The value must be a whole number. The Amount property controls the size of the tiles in the row or column. A setting of 1 means that the tiles remain their original size. A setting of 0.50 makes the tiles one-half of their original size, a setting of 2 makes the tiles twice their original size, and so on. A setting of 0.00 completely turns off the row or column and the underlying material color shows through. The properties in the Transforms, Position, Scale, and Repeat categories are the same as described for an image map. Refer to the Image section for details on these properties. A B C D Figure 17-29. A tiles map can have a custom pattern or predefined pattern. Four of the predefined patterns are shown here. A—Running bond. B—English bond. C—Stack bond. D—Fine running bond.
