Please can you add an ability to manually adjust the order of Junctions and Connections as the tables quickly become difficult to follow. The automatic re-ordering seems to reset as soon as you make any changes!

Check foul and storm phases do not clash where they cross.

How do I transfer my drainage model to and from Site 3D?
In Micro Drainage the transfer is quite straight forward and although it isn't perfect, it is reasonably quick. There doesn't seem to be an obvious way of doing the same in InfoDrainage? Road and Drainage design is an iterative process so easy transfer is essential.

At the moment you can replace areas with Free Form outlines. It would be good if there could be an ability to add additional points or replace with an imported outline

Just like in CAD DrawNet you can use the CAD tools to snap the points of the catchment areas to specific points, it would be useful to have a snapping tool built into the MicroDrainage program. It could be a simple tool so you can either put a new point of the area anywhere, or when you're close to a point of another area you can snap to that point. This would save going back and forth between MD and CAD.

MicroDrainage Network

It would be very useful if it was possible to change the dims of many manholes at once. It'a a very laborious and time consuming task to change each dimension one-by-one, especially if the network is very large!

Can we get a function to lock/retain MH numbers, If you have multiple dummy MH's and need to make changes any name you have given to these is lost when renumbering. You then need to go through the whole process again.

One of the aims of BIM is that all the different models you create match. If you issue a pipe network 3D model for construction with certain pipe numbering and then a minor change happens this can affect every pipe number in the system. But once it's already been issued for construction you can't afford to change pipe numbers as it would be too confusing, which means that the 3D model can no longer match the Microdrainage model.

It would be very useful if DrawNetCAD had the option of updating an existing Civil3D pipe network when using the Export to Civil3D option.
The Autodesk Microdrainage Utility has this ability, albeit it can be unreliable.
