Single / multi

Entering polylines

You can use the Single and Multi options in the input options to specify whether the area consists of a single polygon or a collection of polygons.

Example

Single

Use this to create single, discrete areas.

Multi

Use this to create areas composed of several polygons. Hatching, patterns or fills are given the same group number; rooms are handled as a single entity. This way, you can make a series of separate rooms which the system will treat as a single unit in subsequent evaluations and analyses of the information in the building model. If you selected Multi, you can use Plus and Minus in the input options to specify whether each new polygon is to be added to or subtracted from the overall area.
