Batch Render. This is the trick to make sure you do not tie up your computer when you want to be using it. After you have assigned the light, cameras, models and textures, and you have used the render bitmap tool to check everything, you can set up batch render jobs for you computer to work on while you are on site, at meetings, or asleep.
There are two parts to batch rendering. First you have to define each batch render job, then you have to tell Vectorworks which batch render jobs to do.
