CurveSlice Pro earns a place in the superhive library for pairing interactive, WYSIWYG curve cutting with built-in remesh options, keeping the draw-and-cut workflow inside Blender's viewport.
CurveSlice Pro brings ZBrush-style interactive curve cutting to Blender. You draw a line across any mesh by clicking to place points in the viewport, with no separate curve creation step, then cut with a single keystroke. A live WYSIWYG preview shows a red overlay of exactly what will be removed before you commit.
The add-on offers three cut modes: Trim removes one side of the curve, Slice splits the mesh into two separate objects, and Intersect keeps only the geometry on one side. You can mix Bezier and straight segments — press Alt to toggle — and draw closed loops to punch holes or extract regions, with a fully dynamic cyclic Bezier preview. Smart Close Detection snaps the curve when you hover near the first point, View Lock stops accidental viewport rotation mid-cut, and a viewport HUD shows when cut mode is active.
Auto Remesh cleans up topology after each cut using Voxel Remesh, with QuadriFlow and QuadRemesher integration on Pro. Cutting works in Edit Mode and Sculpt Mode, and built-in mesh statistics display face and vertex counts in the Remesh panel. Version 2.0 adds the interactive drawing workflow and live preview.
Curveslice Pro is best for blender artists who want to slice, trim, and punch holes in meshes by drawing curves interactively in the viewport.
Curveslice Pro is completely free to download and use.
CurveSlice Pro starts a cut with Ctrl+Shift+X or by clicking Draw Cut Curve after you set your mesh as the Cut Target in the CurveSlice panel. Click with the left mouse button to place points, and the red overlay updates in real time to show what gets removed. Press Alt to toggle between straight and Bezier segments, hold Shift to constrain to 45 degrees, and use Backspace to undo the last point. Press F to flip which side is removed, then Enter to confirm the cut or Escape to cancel.
CurveSlice Pro installs like a standard Blender add-on. Download the curveslice_pro.zip file, then in Blender open Edit → Preferences → Add-ons → Install, select the zip, and enable it. From there you select your mesh and set it as the Cut Target in the CurveSlice panel, then you're ready to draw and cut. The add-on handles mode transitions automatically, so you can also cut while working in Edit Mode or Sculpt Mode where those tiers apply.
CurveSlice Pro offers three cut modes. Trim removes one side of the curve, and you can flip which side with F while drawing. Slice splits the mesh into two separate objects along the curve. Intersect keeps only the geometry on one side. All three work with open curves, which cut across the mesh like a knife, and with closed loops, which can punch holes when drawn inward or keep only the interior when set to remove everything outside.
CurveSlice Pro supports cutting in both Edit Mode and Sculpt Mode, and the add-on handles the mode transitions for you. Edit Mode support is available on the Indie and Pro tiers, while Sculpt Mode is a Pro feature. After a cut you can automatically clean up topology with Auto Remesh: Voxel Remesh offers fast uniform remeshing, and on Pro you also get QuadriFlow for quad remeshing that preserves shape and features, plus async integration with the QuadRemesher add-on.
CurveSlice Pro is listed as free in this catalog. For current licensing, device limits, and any differences between the Free, Indie, and Pro tiers — such as Edit Mode, Sculpt Mode, and the remesh options — check the developer's page. Features like Auto Remesh after cut are available on Indie and Pro, while QuadriFlow and QuadRemesher integration are Pro-only, so the developer's page is the place to confirm what each tier includes.
