Resize Mesh Feature

In one sentence: Scale a mesh so that its bounding box matches specified absolute target dimensions in mm.

Overview

Workbench: OpenSCAD
Menu: OpenSCAD → Resize Mesh Feature
Shortcut: none

Computes the scale factors needed to make the mesh's bounding box match the target [lx;ly;lz] dimensions, then applies uniform scaling. The original is hidden and a Mesh::Feature named resize_<original> is created.

Intuition

Where Scale Mesh Feature uses dimensionless multipliers, Resize Mesh Feature uses absolute dimensions. You say "make this mesh 50 mm × 30 mm × 20 mm" instead of "multiply by 2 in X".

When to use it

  • An imported mesh has incorrect dimensions (wrong units, wrong scale) and you need to set it to known absolute dimensions.
  • You know the real-world dimensions of a scanned object and need to apply them.

When NOT to use it

  • For dimensionless scaling — use Scale Mesh Feature.
  • For Part solids — use Part → Scale.

Step-by-step

  1. Select a Mesh::Feature.
  2. Choose OpenSCAD → Resize Mesh Feature.
  3. Enter the target dimensions [lx;ly;lz] in mm.
  4. Click OK. resize_<name> is created.

Parameters

Parameter Description
Target size [lx;ly;lz] — target bounding box dimensions in mm
