Overview of MeshInspector's Select Primitives

Clicking Select Primitives, under the Select tab, enables primitive-level selection.

Use this tool when you need fine-grained selection for detailed inspection, cleanup, segmentation, or precise editing. Once you click Select Primitives, a dedicated panel will open.

Selection Modes in Select Primitives

In the Select Primitives window, choose a selection mode to define how primitives are picked:

• Lasso selects primitives inside a freeform curve you draw.
• Rect selects primitives inside a rectangular area you drag.
• Polygon selects primitives inside a custom polygon you define by clicking its vertices.
• Brush selects primitives along a brush stroke you draw over the target area.
• Pick selects individual primitives by clicking them directly.

Selection Settings in Select Primitives

Additional options refine primitive selection behavior:

• Select Back Triangles includes triangles oriented away from the camera.
• Select Only Visible Triangles limits selection to visible triangles, while also not including triangles occluded by other geometry.

Modifier Keys

Modifier keys change how the current selection is updated:

• None replaces the selection (unselects the previous elements).
• CTRL (or Command) adds primitives to the current selection.
• SHIFT removes primitives from the current selection.
• SHIFT + CTRL (or Command) reverses the selection.
• CTRL (or Command) + A selects all primitives in the currently selected objects.
