Selection

Selection is the foundation of the vcad workflow. Before performing any operation like transforms, booleans, or deletions, you need to select which parts to operate on.

Selection Modes

Single Selection

Click on a part to select it. This replaces any existing selection with the clicked part.

Hover Preview

Before clicking, hovering over a part shows a highlight preview. This lets you see exactly what will be selected.

Multi-Selection

Hold Shift while clicking to add or remove parts from the current selection.

This enables you to build up a selection of multiple parts for batch operations.

Keyboard Modifiers

Visual Feedback

Parts display different visual states based on selection and hover:

Feature Tree Sync

Selection state is synchronized between the viewport and the feature tree panel:

• Clicking a part in the viewport highlights it in the feature tree
• Clicking a row in the feature tree selects the part in the viewport
• Multi-selection works in both directions

This makes it easy to find and select parts regardless of where they appear in your model.

Edge Cases

Overlapping Parts

When multiple parts overlap at the click position, the frontmost part (closest to the camera) is selected.

During Gizmo Drag

While dragging a transform gizmo, selection is locked. Clicks are ignored until the drag completes. This prevents accidental selection changes during transforms.
