One-Click Split is a lightweight tool for cleanly slicing mesh objects into two halves. Users can split meshes along the X, Y, or Z axes in both world and local space, or use a movable guide plane to specify custom angles. The tool includes operations for capping the generated cut surfaces and applying an offset to visually separate the two new halves. It supports evaluated meshes, ensuring compatibility with active modifiers, and safely hides the original object after the operation is complete. It is built for workflows involving hard-surface blockouts, rapid prototyping, and preparing models for 3D printing.
