Different to the horizontal grid, the vertical gridding is not too obvious but still as important as the horizontal grid setup. | Different to the horizontal grid, the vertical gridding is not too obvious but still as important as the horizontal grid setup. | ||
- | In **2.5D | + | In **Concept Design models (2.5D)**, the vertical grid is generated on-the-fly based on the model settings such as building heights. You can change the settings for the vertical grid setup at any time. In **fFull 3D models** the vertical grid is as fixed once you have created the model. The only way to change it is to convert the model down to a 2.5D model (and loose all the extra 3D information), |

For the 3D Main Model, ENVI-met allows two different types of vertical grids: an **Equidistant Grid (A)**, where all grids, except the lowest five, have an identical vertical extension Δz, and a **Telescoping Grid (B1,B2 and C)** where the grid size expands with the height. The figure below shows the differences the different types. | For the 3D Main Model, ENVI-met allows two different types of vertical grids: an **Equidistant Grid (A)**, where all grids, except the lowest five, have an identical vertical extension Δz, and a **Telescoping Grid (B1,B2 and C)** where the grid size expands with the height.
