During research for our back brief presentation for our project we concluded that we will be modelling the Volvo Compact EC55C Excavator. Link to full brochure.
Interior perspective of excavator.
Volvo Compact EC55C
Modelling the excavator - Scale
In the brochure the only dimensions that were available was for the exterior of the cab. We used those dimensions to model the main view port of the interior. All other objects were modelled based on the scale of the cab seat, the cab seat was measured from a 2012 corolla.
Main structure of the model.
Object Modelling
Modelling objects for the interior was straight forward and basic consisting of mostly box's & cylinders. For difficult objects that could not be manipulated from a box were created from splines. The process of using splines was to draw out the shape of the object, once the spline was closed the shell modifier was added to the spline to create the surface of the object. This would then be extruded and converted to a editable poly which then i was able to transform the object by selection of vertex's and edges.
Components
To make placement of objects in the perspectives easier we would attach objects and create them into components. Creating components allows the objects to be group together into one object, this combine object can also be converted to a editable poly and will be transformed as it was one object. The above image shows a 4 objects that will later be attached/combined into the 'joystick' component.
Simulation
When modelling the other objects in the interior, Dara decided to only model objects that are commonly found in excavators. He raises the argument of the end product to be a training simulation of awareness of operating machinery. When operating a excavator only the joystick, levers and foot pedals are consistently used, the operator is only concerned of the job at hand & their awareness to their surroundings. He hopes to achieve similar results to this simulation when in conjunction with UE4 & Oculus.

Test exporting 3DS to UE4.
Texturing for UE4
End result of the excavator model, finishing off with the framing and structure of the cab & the glass panels. The above image shows the model already textured but the when imported into UE4 the textures did not appear. Dara would later discover how to properly texture in 3DS for UE4. Our group has created a step by step guide on how to achieve this here. The video below is a quick chronolapse of Dara texturing for UE4.
End result
Overall i was happy with the outcome of the excavator, the only obvious issue was the lever that was mirrored in 3ds resulting in odd object behaviours. It has now been fixed, relevant files for the 3DS
