• Download snapsplit.zip
• In Blender: Edit → Preferences → Add-ons → Install… → select the *.ZIP → enable.

• Unit system: Metric, Unit scale: 1.000, Length: Adaptive
• The UI is accessible over the N-Panel in Blender.

• Scale Unit = 1.000, Metric: Adaptive
• Before splitting: use f.e. 3D-Printing Toolbox (manifold, thin walls, intersections).
• Select a watertight (manifold) mesh.
• Ctrl + A -> Apply all transforms
• This is also important after each change, f.e. rotatations or scale.
• After splitting: visually check that all parts contain polygons.

Unfold the segmentation part (More...) to get ready for the split.

-> Click "Show split preview" if you want to see the split preview plane permanently. Offset 0 is the middle of the selected part.

-> Choose desired number of parts and adjust the split axis offset. -> Push: "Adjust split axis"

-> For larger part numbers you can deselect "cap seams" and create the caps afterwards. -> Cap seams closes walls, if a pre boolean, hollow or solidify is detected it closes only the side walls to leave the inside open f.e. for casting forms. If none it closes the whole cut area. You can also use it per part afterwards if "Cap seams" is deselected

-> Run "Planar Split"

Build Connections:

Unfold the connections part (More...) to choose and place your connectors.

-> Select two or more adjacent parts (order does not matter). -> Choose pins or tenons, Dovetails or build a Custom Connector distributed along a seam line or spread across a grid, or Placed per click on the cut plane, with or without Snap-Pins for glueless connection. -> Define your tolerance profile (under Connections UI) for your material.

-> Click “Add connectors”: The pin/tenon gets embedded into Part B, and a socket with tolerance is cut into Part A. or -> Choose "Place connectors (click)" to set individualized connectors with your mouse clicking at spots along the seems.
