It is often necessary to edit a mesh using various objects to provide more detail
00:10
and improve the representation of the underlying topography.
00:15
These mesh editing objects can be manually added or taken from external files,
00:21
layers displayed in the GeoPlan view, or objects within the network.
00:27
Mesh level zones can be used to define zones that require ground level modification.
00:33
The ground level at each zone vertex is determined from the Ground Model used during the meshing process,
00:41
or from user-defined values.
00:44
This allows greater flexibility and for sloped surfaces to be defined.
00:49
Adjustments to zone vertex levels are applied and mesh element elevations within the zone are calculated
00:57
from the resulting surface instead of the ground model.
01:01
The method of adjustment is selected in the Type field,
01:05
which has numerous options.
01:07
For instance, you can select the Rel. to highest option in combination with Raise to efficiently set a flood threshold level for buildings,
01:18
against the highest ground level vertex.
01:21
Visit the InfoWorks ICM Help topic, Mesh Level Zones, to familiarize yourself with the available options.
01:29
In the 3D view window for this example, the bridge and road deck have been cleaned from the ground model,
01:37
which is common.
01:39
As this represents an important flow path, the goal is to build it into the mesh.
01:45
Start by adding a new polygon object, ensuring that you place a vertex at each corner where the ground model level is correct.
01:53
You could add more vertices, if needed, to define a more complex profile.
01:59
To quickly add the road surface for a bridge into the mesh,
02:03
open the Properties window for the new object, and set the Type field to Specify.
02:10
Then, next to Vertices, click the Ellipsis (…) button to open the Vertices table.
02:16
For the Specify type, elevations at mesh level zone vertices are set to a user defined value,
02:24
obtained from the ground model, or interpolated from other zone vertices as specified.
02:31
This allows you to change the topography of the mesh level zone, as individual vertex elevations can be adjusted.
02:40
In this case, set all the Vertex elevation type fields to Ground model.
02:46
This generates an interpolated surface between them.
02:50
You can also make an additional elevation adjustment, if necessary.
02:55
Regenerate the mesh to include the changes from the mesh level zone.
02:60
Once complete and loaded, the effect is best seen in 3D view.
03:05
The 2D elements within the mesh level zone now have ground levels set from the interpolated levels
03:12
to form a high-level road deck.
03:15
The next consideration for this model is whether flow should be allowed to pass under the road deck,
03:21
which requires the use of a conduit 2D link.
03:25
Note that if changes are made to a mesh level zone after meshing the 2D zone,
03:31
you must recalculate mesh elevations within the 2D zone.
03:36
This can be done by resampling elevations for selected 2D zones.
