Mike + added a function called "show data errors" in its new product in 2021, which can display objects that lack necessary field information and generate a table. This function can improve the ability of model engineers to deal with model errors more quickly. I hope ICM can add this function

The status bar currently only displays levels (ground model level, water depth) to 1 decimal place. 2 Decimal places would be much more useful, Especially to ensure a node is at a low point or in the gutter invert..

On a Long-Section of a pipe, I would like ICM to show the unconnected pipes which cross that long-section. This would illustrate potential pipe clashes.

I imagine the unconnected pipes would be shown as circles on the long-section similar to how connected pipes are currently shown.

HEC-RAS has a tool in RAS Mapper doing just that.

It happens too often that while merging different models, you suddenly need a different timestep for your level-file. The only way to do this now, is remake your level completely. It would be better to (when changing the timestep of your level) ICM would ask what do : automatically interpolate the new in between time steps, put the in between time steps on zero,...

Import CAD files as a background, network, and/or to be able to utilise it to create a surface from.

When importing from autocad layer mapping can be used to create a model layout for things like 2D Mesh zones but all created objects are null. I have written an SQL to apply parameters to all null mesh zones and roughness zones and import each layer individually. If the autocad layer was written to usertext1 I could import all at once with a saved layer mapping and then enter all parameters by selecting usertext1

Being able to insert channels into terrain rather than editing in 12D or other software would be more practical for smaller firms to turn around modelling ideas.

Landscape packages allow terrain meshes to be manipulated with tools that sink into mesh easily. Channels and swales need slope, not simply vertical depression to model correctly. XPStorm allows 1D modelling but this isn't useful for presentations and Civil 3d and 12d are catching up quickly now that rational method is being phased out.

I am trying to calculate the excavation/fill volume by comparing my existing model with the proposed one. I know we can open simulation results with “As alternate results for comparison” which allows us to compare flooding depth from two different scenarios. I expect to have something like this for ground surface as well so that we can see the different ground elevation visually and/or numerically.
