Place Helper
An add-on for efficient placement of objects（One handed placement, dynamic physical placement, and dragging to copy along the axis）
Move Pro（Place）
01 The revolution of 3D software – objects can rotate simultaneously while moving.
Almost all 3D software Move and Rotate are two separate tools, but this does not conform to the logic of the real world, as we rotate objects simultaneously when placing them. This means that you are using the most basic yet tedious functions every day, and now it’s time to get rid of them
Shortcut keys: After entering the tool, drag with the left button to move, and the scroll wheel can rotate (Ctrl=smaller angle, Alt=larger angle)
Extra tips：Select an object, press and shake the mouse directly in the new position, and the object will appear directly in the new position. (Inspired by Red Alert 2: Chrono Legionnair）.
02 Quick Copy
Select an object, hold down Shift and press the left button at a certain position to shake it, and a new copy will be generated at this position.
03 Anti insertion detection
When the mobile model intersects, boundary markers will appear.
Transform Pro
Hold down Shift and drag the axis Gizmo to copy along the axis. Note that this also applies to editing mode, just like C4D.
Dynamic Place(Real time physical placement)
01 Drag Mode
Select one or more objects and drag the axis to generate real-time physical simulation effects. Unselected objects will become collision objects.
02 Scale Mode
Unlike Drag, Scale simulates attractive/repulsive forces from the center, in order to scatter or gather objects
Note: Active and passive objects can be placed in a collection to block other objects and improve performance. Special note: Just like other simulation programs, excessive computation may cause lag or even crashes
The End
Like Simple Deform Helper, this is a tool that has been planned for development since 2022. Officially open sourced and released in 2023. Thank you to our friends who have always helped us. Without you, it wouldn’t have appeared. Meanwhile, if you feel any problems with the English description, please feel free to contact me on GitHub. I hope to make improvements as soon as possible.
PLACE HELPER V2.0 CHANGELOG:
Welcome to version 2.0.0
Place Tool
Drag to place objects on surfaces with normal alignment and collision detection
Shift + drag to duplicate while placing
Alt + click to set the placement axis via gizmo
Use Object Up Axis — per-object up axis (same behavior as BAS Place); scene-wide axis when disabled
Alt + drag for box selection; first selected object is promoted to active after box select
Limit to Ground — prevents objects from going below Z = 0 while moving
Rotate / scale gizmos; drag + mouse wheel to spin; Ctrl + Alt + wheel for 90° steps
Transform Pro
Left-drag to move objects directly in the viewport
Shift / Alt + drag to duplicate while moving (Instance / Object via toolbar)
Double-click object to enter Edit Mode; double-click empty space to exit (auto-switches to Transform Pro Edit)
Optional Show Gizmo toggle (off by default)
Shift + drag in Edit Mode to extrude mesh geometry
Scatter Tool (New)
Brush-based scattering with density (instances per unit area)
Radius, density, and scale support pressure sensitivity and random ranges (via popover menus)
Random spacing, random height, and stacking mode
Source probability weights with randomize; Apply and Clear scatter
Limit to Surface — skip samples outside the target surface
Slope / height filters and image-based density mask
Alt + wheel or [ or ] to adjust brush radius; Ctrl + drag to erase
Alt + drag on empty space to box-select scatter sources
Custom UI icons: STYLUS_PRESSURE for pressure, dice icon for random
Dynamic Place
Gravity Dynamic Place — drag objects with gravity simulation
Force Field Dynamic Place — drag or scale to apply force field effects
General UX
Tool Help overlay in the lower-left corner (English / Chinese), toggle in toolbar
Help offset defaults: 60, 60 (configurable in preferences)
Esc on any tool exits to the built-in Box Select tool
Streamlined scatter toolbar — height and duplicate moved into the settings popover
Other
Improved overall code quality and maintainability across all tools
Fixed crashes on undo in the scatter tool (stale RNA / collection references)
Fixed tools becoming inactive after opening a new scene or reloading a file
Fixed placement tool losing the active object after box selection
Fixed box select conflicting with object move in Place and Transform Pro
Fixed double icons on scatter popover buttons
Fixed circular import error on addon registration (resolve_place_axis)
Fixed scatter instances placed outside the target surface when brush radius exceeds the plane
Fixed SyntaxWarning and keymap not found warnings on startup
