I've created a windfarm infrastructue model in Civil 3d and have brought it into IW (see screenshot) and I now have modified some road alignments in Civil 3D and want to bring them into IW.
I can only see the creation of a new IW model as being the way to show my alternative as the IW proposals workflow doesn't seem appropriate for my purposes i.e. the terrain would go very wrong if I mixed data in the same IW model.
Any comments on the way to go about this?
I've never fully explored proposals as the only time I did it corrupted my model.
All the data for the model is generally Civil surfaces imported via IMX - all terrain surfaces seem to just stack on top of each other to make a composite terrain and the highest terrain always "wins".
I'm primarily using IW as a visualisation tool (probably not what is was designed for and 3ds Max would be better but that has a steep learning curve) to produce flythroughs.
I believe separate proposals are the best solution for this. Your Master proposal should only have existing conditions, and you should have a separate Proposal for each design option.
Also, you can control the priority order of surfaces by using the Manage Surface Layers tool (Ribbon - Home tab - Explore panel). You can select the objects that make up your surface, and move them up or down in the list to set which objects take priority over others.
I wasn't aware of the surface priority method - I'm going to play with that right now.....
I'll certainly be giving proposals another try - the Infraworks stuff is done right at the end of a project and by the time I've completed what i need to do I need to move on to another project so I don't get much time to experiment.
From the replies thus far, proposals may be a useful tool to get to know....
