Patchwork 3D 2024 X7

Positioning Surfaces from the Main Interface

Patchwork 3D includes an area in its interface specifically for editing the positions of surfaces. This editing area is beneath the 3D viewports in the workspace. It allows for directly entering numerical values for the position of surfaces relative to axes X, Y, and Z.

Editing area dedicated to surface positioning.

The toggle button Enable user input for absolute coordinates image64.png in the toolbar is for displaying or hiding this editing area. Entering numerical values for these parameters is only possible when a surface is selected.

The toggle button Keep Ratio viewport_linked_with_shaper_2.png of the Scale box affects the scaling behavior of selected surfaces. You can indeed choose to keep the same dimensions on all axes (X, Y, and Z) and to have a uniform scaling viewport_linked_with_shaper_2.png or on the contrary choose not to have a uniform scaling on the three axes (X, Y, and Z) viewport_linked_with_shaper_1.png. Here you will find explanations on how the scaling works.

Coordinates in World Reference Frame

The Translation and Rotation boxes are for specifying the surface’s translation coordinates (TX, TY, and TZ) and the rotation orientation (RX, RY, and RZ) of the selected surface’s pivot relative to the World frame. The selected surface remains fixed relative to its own pivot.

Note

In the Pivot mode, translation and rotation tools affect pivots only instead of affecting surface-pivot couples, which they do in the other modes.

Coordinates Relative to Parent's Pivot

The Translation and Rotation boxes are for specifying the position coordinates (TX, TY, and TZ) of the pivot’s origin and the angular coordinates (RX, RY, and RZ) of the pivot for the surface selected relative to the pivot of its parent in the kinematics chain.

When no parent is defined for the surface selected, the values entered are considered to apply to coordinates in the world frame reference like in the first box.

Relative Translation and Rotation

The function Enable user input for relative rotation or translation image65.png may be accessed only when either the Translation or Rotation gizmo is activated. It displays the Relative translation or rotation dialog box.

The value by which the surface selected is translated relative to the frame of the gizmo displayed is entered in fields TX, TY, and TZ. The value by which the surface selected rotates relative to the axes of the frame of the gizmo. The frame of the gizmo depends on the frame of reference selected.

The cube's translation gizmo origin is located at XX X=-0.4 m.
A translation of 0.3 m in the direction of the World frame’s X axis is applied to the cube.

The cube's translation gizmo origin is located at XX X=-0.4 m (on the left). A translation of 0.3 m in the direction of the World frame’s X axis is applied to the cube (final position on the right).

Applying a Transformation to a Selection of Surfaces

Two modes exist to apply a transformation to a selection of surfaces:

Transform selected surfaces regarding the pivot of the leader of the selection image67.png: the transformation is applied to all selected surfaces relative to the selection leader (displayed in white).

Transform selected surfaces regarding their own pivot image68.png: the transformation is performed for each surface relative to its own pivot.

Defining the Step Values

The box on the right side of the area dedicated to positioning surfaces allows users to define fixed increments of movement or rotation for using the gizmos while holding down the Alt key.
