This section overviews some additional tools that are also part of the add-on.
Move Along View
Keyboard Shortcut: Ctrl-Y
Move Along View allows you to move vertices and objects along a viewport’s line of sight. This is useful when creating a 3D model or placing objects using a 2D sketch or photo as a reference. To use:
Select the vertex or object that you wish to move along the viewport’s line of sight.
With the mouse hovering in the view you wish to move along, press Ctrl-Y (default) or press the Move Along View button in Perspective Plotter’s side panel.
Moving the mouse will change the position of the vertex or object along the view. Guide lines are displayed in other top/down or left/right viewports to show where the view line is.
Left-click the mouse button to commit the position, or right-click to cancel.
You can change the viewport shortcut under the add-on’s Preferences section.
There is an alternate method in Blender for doing this, and this tool is provided for convenience so that you do not need to switch modes whilst modelling.
Curve control points are not currently supported.
This works by updating Blender’s scene resolution to match the background image. All camera borders share this resolution. Changing one camera border dimensions changes every other camera border in the scene.
The Add-On comes with a button that allows you to automatically set the scene resolution to a camera’s background image or video.
You will need to set a background image or video before pressing the button:
To set a background image or video, in the Outliner panel click on the camera object to select it.
In the Properties panel click on the camera properties tab.
Select the checkbox for Background Images, then click on the Add Image button.
Select Image or Movie clip, and click on the Open button.
Locate and select your background image or video and click on the Open Image button.
Now, in the Perspective Plotter panel click the “Match Background” button under the Tools tab:
Flatten Horizon Line
Flatten Horizon Line will attempt to adjust vanishing points to make the horizon horizontal. Click the button on the panel and the control points will be adjusted to flatten the horizon.
