To speed up adding detail cuts to 3D models, simplify the base mesh first—use decimation or LOD tools to lower polygon count before working on precise cuts.
Fewer polygons mean faster editing: Excess vertices slow down detail work, so simplifying removes that bottleneck. Use boolean tools for quick, clean cuts (fix topology afterward) or edge loops to guide where details go—this keeps the mesh organized.
For complex models, try layer-based editing to isolate the area you’re cutting. This lets you focus without slowing the whole mesh.
Stick to a low-poly base and add subdivision surfaces later—this keeps your workflow efficient while maintaining detail quality.
