A projection is a shape created in one source and visualized in another, most often in 3D and projected into 2D.

Control which projections are active with these options (Top menu -> View -> Projections).

- **Cone shape (3D) - **Highlights the point cloud with a cone shape from a selected 2D box or by highlighting an area in the 2D miniature image with `shift` and drag.
- **Selected object (2D)** - Shows the 3D->2D projection of the selected 3D object in the 2D miniature image, or in the 2D view.
- **All objects (2D) - **Shows 3D->2D projections of all 3D objects in the 2D miniature image, or in the 2D view.
- **Selected trajectory** - Shows a 3D->2D projection of the trajectory of the selected 3D box in a 2D miniature image, or in the 2D view.
- **Search light** - Highlights the point cloud at the current cursor position in the 2D miniature image. **Cone shape (3D)** must also be active for the search light to be visible.

If you have an object in 2D that you want to draw in 3D, you can

::::WorkflowBlock
:::WorkflowBlockItem
Enable **Cone shape (3D)** projection
:::

:::WorkflowBlockItem
Mark a 2D object in the objects list or the 2D view
:::

:::WorkflowBlockItem
Go to the 3D view
:::

:::WorkflowBlockItem
Follow the purple-colored projection to find the 3D points belonging to the object

If you don't have a 2D box or quickly want to create projections onto the 3D point cloud

::::WorkflowBlock
:::WorkflowBlockItem
Enable **Cone shape (3D)** projection
:::

:::WorkflowBlockItem
Go to the miniature 2D image in the 3D view
:::

:::WorkflowBlockItem
Press `shift` and drag the cursor over the area in the 2D image you're interested in
:::

:::WorkflowBlockItem
Follow the purple-colored projection to find the area of interest.

## In the 2D view

You can choose if you want to show the projection of the currently selected object. As well as if you want to show the projection of all objects when no object is selected. Selecting an object will hide the projections of all other objects.

If the scene has the available data, you can also select if you want to project the trajectory of 3D boxes into the 2D image.
