Object Booleans

The JMesh Tools panel includes Object Booleans tool with four operations:

• Difference - Subtracts the selected object from the target
• Union - Combines both objects into one
• Slice - Cuts the target along the selected object's boundary
• Intersect - Keeps only the overlapping volume

Select an object, set your target in the panel, and click the desired operation.

Shape Booleans

These are the core features of JMesh Tools. It allows you to draw 2D shapes directly onto mesh surfaces in the 3D viewport.

Works in: Object Mode, Edit Mode, and Sculpt Mode

Available shapes:

• Circle
• Rectangle
• Polyline
• Curve

The current operation is displayed in the lower left corner of the viewport.

Example: Cutting a Circle into a Mesh

1. Enter Shape Booleans tool (Tools Panel on the left)
2. Ctrl + Left Click on a mesh to place a circle
3. Press O to set the operation to Difference
4. Press E to extrude, then Left Click to confirm the depth
5. Ctrl + Left Click to apply the boolean cut
6. Press Escape to exit

Shape Library

The Shape Library lets you save and reuse custom 2D shapes for boolean operations.

Features:

• Export shapes to JSON files
• Import previously saved shapes
• Load default shape presets with one click

Usage:

1. Draw a shape in Shape Mode
2. Export it to your library
3. Import and reuse it anytime
4. Default shapelib is included

Editable Shapes

Shapes can be edited after creation. Enter Edit Mode to adjust individual vertices before applying the boolean operation. This is useful for creating custom panel lines or non-standard cut patterns.

Bevels

Add smooth, properly shaded bevels to any object.

1. Select an object
2. Click Bevel in the JMesh Tools panel
3. Adjust settings in the popup:
• Segments - Number of bevel subdivisions
• Width - Bevel size

Arrays

Quickly add Array modifiers to objects.

Linear Array:

1. Click Array in the panel
2. Set the number of copies in the popup
3. Click Apply when finished

Circular Array:

1. Click Circle Array in the panel
2. Set the number of copies
3. The objects are distributed radially around the origin

In Shape Mode, circular arrays are also available via the blue shape action button.

Clothify

Add a cloth simulation with pressure to any mesh with one click.

Setup:

1. Create a mesh (e.g., a subdivided plane)
2. Click Clothify in the JMesh Tools panel
3. Adjust settings in the overlay:
   • Pressure - Inflation strength
   • Shrinking - Fabric tension
4. Click Start to run the simulation

Edges are automatically pinned to maintain the boundary shape.
