SketchUp

There are three sets of controls that are accessible during matching mode. These controls are: The matching controls that appear over the photo, the controls that appear in the Match Photo dialog box, and the matching context-menu items.

Matching controls appearing over the photo
Matching controls appear over your photo during matching mode. A description of these controls follows:

Origin
The origin appearing in matching mode is used to identify where the three axis meet and is used to help you create geometry aligned to the photo. The location of the origin depends on the type of photo:

• For photos that are usually taken indoors where walls, ceiling, and floor of a room meet at a corner, the origin is usually at the bottom corner where the walls, ceiling, and floor meet.
• For photos that are taken from a vantage point where you are looking down on the building or structure, the origin would be at the top corner of the building where roof and walls meet.
• For photos that are taken from a vantage point where you are standing on the ground, the origin would be the bottom corner where the walls and ground meet.

Axis lines extend out from the origin. You can click on an axis line and move the cursor along the axis line to increase or decrease the size of the geometry that you have drawn. Following is an image of the origin and axis lines:

Vanishing Point Bars
There are four vanishing point bars in matching mode, two red bars and two green bars. Each bar is represented as a dashed line with square bar grips at the end. These bars are further used to align the axis to the photo. Following is an image of the vanishing point bars:

Match Photo dialog box controls

Refer to the Match Photo dialog box for an explanation of each of the controls in the Match Photo dialog box.

Matching context-menu items

Context-click during matching to display the matching context-menu.

Done
Select the done menu item to end your matching.

Start Over
Select the Start Over menu item to restart matching.

Cancel Match
Select the Cancel Match menu item to cancel and exit your matching.

Zoom Matched Photo
Select the Zoom matched photo menu item to fit the entire drawing area.

Zoom Vanishing Points
Select the Zoom vanishing points menu item to zoom to fit all vanishing points in the drawing area.

Rotate 90 Left
Select the Rotate 90 left menu item to rotate the red and green axes 90 degrees left. Use this menu item primarily when creating a model to match several photos (to rotate the model as you draw the model's sides to match the different sides of the structure in different photos).

Rotate 90 Right
Select the Rotate 90 right menu item to rotate the red and green axes 90 degrees right. Use this menu item primarily when creating a model to match several photos (to rotate the model as you draw the model's sides to match the different sides of the structure in different photos).

Undo
Use the Undo menu item to undo the last matching command.

Redo
Use the Redo menu item return the last undo to its previous state.
