ShapeUp is a tool to define your shapes BEFORE creating the shape layers and adding them to your composition. It creates "clean" shapes, either AE's native parametric shapes or ones using custom paths (without utilising merge paths). Rounding and zigzag vector filters may get added for corresponding shapes. Neither expressions nor animations will be applied. As said - clean - to get you started. Just try the demo version and have a look at the user guide linked below.
