Autodesk Showcase is an extremely useful tool for quickly visualizing and presenting models to your clients. This entry will be a short introduction to the program, but there are quite a lot of additional functionality that will make your presentations stand out. For more information, you can follow this YouTube link, where Brian Mackey presents a general overview of Showcase.
You will be able to use your Revit model in Showcase, by accessing the Suite Workflows command from your Application Menu. You will be able to send your model to either 3ds Max, or Showcase. For Showcase, you can present your conceptual model, create an interactive walkthrough or even create a realistic presentation for rendering and/or animation purposes
We can choose between a wide variety of environments for our model. A Grass Field environment was chosen in this example.
In my opinion, one of the best Showcase features is that one can make adjustments to the scene's lighting, as well as shadows on the fly
Animations, walkthroughs as well as flythroughs can be created by creating shots of the scene.
One can also paint model elements to quickly present another material option to a client.
To complete a rendering, one can set the scene's visual style to Raytrace, and save the image to a specific file format.
Painting can easily be done by a window selection as well.
In a nutshell, even though Showcase is not 3ds Max, it is a viable solution for quickly visualizing and representing your designs and/or options to clients
