Create a proposal that illustrates the changes you plan.
Proposals give you the ability to explore various development alternatives for the development of a given area within your city model. Once the base model is constructed, you can start the conceptual design process by creating one, or more, proposals. One proposal may spark the need for further proposals as more ideas come to light.
If multiple proposals are created, you can compare them to one another and choose the best one to merge with the base model. If two proposals have complimentary design elements, you can merge those elements into a single proposal before merging it with the base model.
You can open proposals from within the base model on which they are based. You cannot open them independently.
Before creating a proposal, you need a city model. If you don't have a base model created, see the Build a Model workflow.
