A space style is a set of parameters that determines the appearance and other characteristics of the space object to which it is assigned. Depending on the scope of the drawing, you may want to create different space styles to represent different types of spaces, such as different room types in an office building.
Within the space style you can set up the space decomposition. Decomposition geometrically divides an existing space into triangular or trapezoid subparts. In some countries, such as Germany and Japan, the visual decomposition of spaces into subdivisions is needed for the space proof that must be presented to the building administration for approval.
You can use styles for controlling the following aspects of spaces:
- Boundary offsets: You can specify the distance that a space's net, usable, and gross boundaries will be offset from its base boundary. Each boundary has its own display components that you can set according to your needs.
- Name lists: You can select a list of allowed names for spaces of a particular style. This helps you to maintain consistent naming schemes across a building project.
- Target dimensions: You can define a target area, length, and width for spaces inserted with a specific style. This is helpful when you have upper and lower space limits for a type of room that you want to insert.
- Displaying different space types: You can draw construction spaces, demolition spaces, and traffic spaces with different display properties. For example, you might draw all construction areas in green and hatched, and the traffic areas in blue with a solid fill.
- Displaying different decomposition methods: You can specify how spaces are decomposed (trapezoid or triangular). If you are not working with space decomposition extensively, you will probably set it up in the drawing default.
