# Front / Back
These settings control the front and back portions of the spaceship which are used for smoothing, extrusions to create shapes for wings or bridges.
Figure 1
These are the **Front/Back** properties and what they do:
### Ship Front
This allows you to switch the front of the ship to face either the -Y or +Y axis.
Figure 1
### Front Scale
This scales the front of the ship in the x, y and z axis.
Fgiure 2
### Back Scale
This scales the back of the ship in the x, y and z axis.
Figure 3
### Expand
This expands the amount of faces used for the **Front** and **Back** portion of the ship.
Figure 4
{% hint style="info" %}
*Properties below works when using an Expand value of 1 and above except for Smooth which works for all values. 0 means the front or back only contains the faces that face the -Y or +Y axis.*
{% endhint %}
### Smooth
Allows you to smooth the **Front** or **Back** of the ship.
Figure 5
### Bridge Tol
Face normal threshold by which to include faces when extruding using the X and Z depth properties.
Figure 6
### X Depth
Extrudes faces towards the -X or +X axis in the **Front** and **Back** of the ship.
Figure 7
### Z Depth
Extrudes faces towards the -Z or +Z axis in the **Front** and **Back** of the ship.
Figure 8
### X Taper
Tapers the extruded face using the X Depth property.
Figure 9
### Z Taper
Tapers the extruded face using the Z Depth property.
Figure 10
### Edge Cuts
Adds lateral edge cuts to the extruded faces in both X and Z axis.
Figure 11
More faces added to the mesh basically means other properties that alters the shape have more face to play with.
The **Front**/**Back** section is what creates these bridge or cockpit looking shapes that are purely random but the all the shape changing settings help to bring them out.
Figure 12
This section has no random seed property but think of this as an extension of the hull where its random seed property can be used to randomize their result.
