There are two different types of objects - objects and splines. Open the Objects Menu by clicking on the Objects Tab. (F3)



The default mode is Add Objects. Begin by scrolling through the list of objects by clicking on the left and right arrows of the object list. The selected object shows as a rotating 3D object in the viewer window.


Object add.jpg Add Object

Check that you are in Add Object mode, or Click on Add Object (A) to select this mode. Click on the terrain and the selected object is placed wherever you click. You can repeat this several times quickly adding a number of trees or buildings.

Object move.jpg Move Object

Click on the Move Object (M) and Click and hold on any object and then drag the object around the terrain to new positions.

Reload page.jpg Rotate Object

Click on the Rotate Object (R) and Click and hold and move the mouse left and right to rotate the objects. A display shows you the number of degrees of rotation. You can set objects to “randomly rotate” or not by choosing the Randomly Rotate option in the Surveyor Options menu from the Main Menu.

Object get.jpg Get Object

Click on the Get Object (G) tool and then Click on an object already placed on the terrain. The object selected now appears in the selection window. Change the mode to Add Object (A) and Click again on the terrain where you wish to place another copy of the newly selected object.

Area cancel.jpg Delete Object

Select Delete Object (D) then Click to delete an object. Continue Clicking to delete a number of objects. If you click on the wrong object, click on Undo (Ctrl-Z) to undo the last action and replace the last deleted object.

Height adjust house.jpg Height Adjust

Click on Height Adjust (H) to enable the adjustment of the height of any Object. Only objects which have been designed to be height adjustable will allow you to adjust their height. S Holding the Ctrl key in conjunction with this move will adjust the object’s height in increments of 0.1 units and holding the Shift key will change the height by units of 0.05.

Edit properties.jpg Edit Properties

Click on Edit Properties (N). Then Click on any object in your route. A menu will then open up allowing you to edit the properties of the object.


Splines are generally long thin objects such as roads, power lines, fences and rows of trees. They consist of two or more “spline points” denoted by white circles. These spline points can be placed any distance apart and the spline object is then “stretched” between the spline points as you place them on the route. To enter Object Spline mode, Click on the large Spline Mode (S) button at the top left of the tab menu.

Object add.jpg Add Spline

Click on the terrain to anchor the first spline point, and Click again some distance away to place the second spline point. You will see white circles at each end of the spline. These spline points determine the points of a spline that may be selected or moved. To extend the spline further, Click again on the last spline point, then Click once more nearby to extend the spline. Holding down the Ctrl key then placing several spline points is another way. Release the Ctrl Key and place your final spline point to anchor the spline in place

Object move.jpg Move Spline

Select the Move Spline (M) tool and then Click and hold while dragging the spline point to a new position. To set the spline poit at a specific location, hold the Shift key when placing it. This shortcut can be used to place spline on top of one another.

Split spline.jpg Split Spline

If a spline is already curved, you can split it into two sections by using the Split Spline (Q) tool. Click on the middle spline (or any non-end spline point) to separate them.

Object get.jpg Get Spline

Click on the Get Spline (G) tool and then Click on a spline object already placed on the terrain. The spline object selected now will appear in the selection window. Change the mode to Add Spline (A) and Click again on the terrain where you wish to place the newly selected spline object.

Area cancel.jpg Delete Spline

Click on Delete Spline (O) then click on a section of spline between two adjacent white circles to remove unwanted spline sections. If you delete a section that is not an end section of a spline, the spline will be split into two splines.

Straighten spline.jpg Toggle Traffic

Many roads will have vehicles travelling on them automatically, this can be seen while in Surveyor after placing the roads. Clicking on Toggle Traffic turns all traffic off on the roads.Clicking on the button again will have traffic resume.When toggling traffic on and off, it affect all spline roads on your route.

Edit properties.jpg Edit Properties

Click on Edit Properties (N). Then Click on any object in your route. A menu will then open up allowing you to edit the properties of the object.


Click on the Advanced Menu (Shift F3) to access even more tools. A drop down menu is then revealed.

Spline height.jpg Spline Height

The Spline Height (H) tool can be used to raise or lower the height of certain types of splines (for example catenaries or road bridges). Click on Spline Height then Click and hold on a spline point (the white circle) and drag the mouse forward or backwards.

Spline point delete.jpg Delete Spline Point

Click on Delete Spline Point (X) and then Click on a white spline circle to remove unwanted spline points. You cannot delete an end spline point, but you can delete the whole section using the Delete Spline (D) tool.

Spline point insert.jpg Insert Spline Point

Click on Insert Spline Point (I) then Click between two existing spline points. Notice that a new spline point is created.

Spline smooth.jpg Smooth Spline

Smooth Spline (S) levels the track between two spline points, bringing the land up or down to match the levelled spline.

Vertex height get.jpg Get Vertex Height

Click on the Get Vertex Height and Click on the highest spline point on your spline. The height is displayed in the Height Value box.

Vertex height apply.jpg Apply Vertex Height

Click on Apply Vertex Height then Click on another spline point. The spline point is raised to the same height as you first vertex.

Gradient remove.jpg Remove Gradient

Click on Remove Gradient and then Click on a spline section to remove the gradient between two spline points.

Edit properties.jpg Edit Propertires

This can be used to name the spline and also set its layer.
