Linear and circular arrays

中文

Enter multi-selection in Geometry, select objects or groups, and click the array button. Counts include the original: a 3 × 3 linear array contains nine instances. Circular arrays use the configured angular step while preserving each object's orientation.

Expand and edit

  1. Expand the array group, then expand the original marked as the editable source.
  2. Select an ordinary object to edit its dimensions, position or material in Inspector. Select an advanced group to reopen its generation parameters.
  3. Successful edits update every instance. Circular placement uses the latest source bounding-box center while retaining the configured axis and angle.

Other instances are read-only. You can inspect or focus them, or choose Edit source to jump to the corresponding original. Replicas cannot change visibility, color or structure, and cannot be copied, deleted or dragged. Ordinary position fields use world coordinates; generator parameters use the generator's own local coordinates.

Nested groups and source structure

Ordinary groups can contain subgroups, and array sources can contain other arrays. Add, delete, copy and reorder objects or groups inside the original; every instance continues to share that source structure. Removing the last source object is rejected to prevent an empty array source.

An inner array's original is editable only inside the outer original. Everything inside an outer replica remains read-only. Opening 2D Editor from a source limits editing to that source's scope.

Parameters and saving

Select the array group and open its generation parameters in Inspector to change the mode, count, spacing, angle or reference plane. If the source or model settings change while the editor is open, reopen it before applying changes.

Project files store the source subtree, generation parameters and attachments. The original remains editable after reopening. Exporting .in expands the current source into standard geometry commands.

Nested expansion is limited to 10,000 instances, 50,000 ordinary geometry commands and 2,000,000 voxel boxes. Operations exceeding those limits are not committed. Advanced generators retain their existing regeneration requirements when grid or material settings change.
