Scale Tool
From K-3D
Overview
The Scale Tool is used to scale nodes interactively, by dragging the mouse through a Viewport Panel.
Usage
Look at a selected cube in the front view.
From the main toolbar click on the scale tool.
It is now activated.
The yellow manipulator indicates the scale constraint.
- middle sphere - scales all three axes: .
- manipulator axes (arrows) - scaling constrained to a single axis: , , .
- manipulator planes (squares) - scaling constrained to two axes: , , .
See below X-axis constraint.
And YZ-plane constraint.
Now there are two ways to scale the object using the highlighted constraint with left mouse button (LMB).
- a single click - click > move mouse > click again to stop
- a mouse drag - hold button down > drag > release button
To cancel the scaling, click the right mouse button (RMB).
- in single click mode - LMB click > mouse move > RMB click
- in mouse drag mode - hold down LMB > drag > RMB click > release LMB
Clicking the RMB in any other state will switch back to the Selection Tool (deactivate the scale tool).
If you need to carefully ajust the scaling near a manipulator, click on the middle mouse button (MMB) to hide them. Click again the MMB to bring them back. Note that is doesn't work when moving.
World and local modes
Control-MMB click toggles between world and local modes :
- in world mode, moving the manipulators scale selected objects as a group in world space
- in local mode, moving the manipulators scale each selected object within its local space
In local mode, Shift-MMB click scale the manipulators through the set of selected objects.
Scale Points
Note: The tool is still in development and currently only works on objects, and not on any object component (face, edge or vertex). To scale points without the tool:
Select the points to be scaled. Click the RMB (Right Mouse Button) on the selection. This will bring a pop-up menu, select Modifiy > ScalePoints, proceed to scale the points using the Node Properties Panel.
