Object Openings - Concepts

Object Openings are used to let light pass through adjacent object surfaces (openings must be created in both entities) or from exterior to interior. When Daylighting calculations are desired, a Daylight Opening or Daylight Window must be added within the Object Opening for calculation purposes.

Rules for creating flat bottom openings

  1. Openings must be contained within the surface. Attempting to locate a vertex outside the surface will prompt a warning.
  2. The sides of an opening must not cross one another.
  3. Openings can be of any shape and may include arcs (F4).
  4. Openings can be created in either clockwise or counterclockwise directions.

Limitations of flat bottom openings

  1. Openings cannot be edited in any way, they are fixed.
  2. Openings cannot be copied or arrayed at this time.
  3. Modifications in Object height do not effect flat bottom openings.

Rules for creating side openings

  1. Openings must be contained within the surface. Attempting to locate a vertex outside the surface will prompt a warning.
  2. The sides of an opening must not cross one another.
  3. Openings can be of any shape and may include arcs (F4).
  4. Openings can be created in either clockwise or counterclockwise directions.

Limitations of side openings

  1. Openings cannot be edited in any way, they are fixed.
  2. Openings cannot be copied or arrayed at this time.
  3. If  Object height is increased, the opening will stay in the same location relative to the base elevation.
  4. If Object height is decreased, all side openings are lost.

Rules for creating top openings

  1. Openings must be contained within the surface. Attempting to locate a vertex outside the surface will prompt a warning.
  2. The sides of an opening must not cross one another.
  3. Openings can be of any shape and may include arcs (F4).
  4. Openings can be created in either clockwise or counterclockwise directions.

Limitations of top openings

  1. Openings cannot be edited in any way, they are fixed.
  2. Openings cannot be copied or arrayed at this time.
  3. Modifications in Object height will cause all Top openings to be lost.
