# 9.3 - 3D Chart

Displays a 3D representation of the well path, plotting North/South vs East/West vs TVD.

The chart can be rotated and panned around the centre point using the mouse with the left mouse button depressed. The centre point can be adjusted by holding **Shift** and using the mouse with the left mouse button depressed if the option ‘Center on survey’ is not toggled on.

The plot is zoomed in and out using the **+** and **–** keys or by scrolling the mouse wheel.

The 3D chart has a different right click chart menu to the other charts.

The **Center on survey** option will zoom and centre the 3D plot on the reference well when selected. I also allow the user to manually move along the wellbore points using the **↑** and **↓** keys. In this state the chart displays the reference well point coordinates data and the up/down, left/right and centre to centre distance in relation to the currently selected offset well. The **North Ref Distances** option will toggle this distance between high side reference and north reference. The offset well can be individually toggled through all the currently displayed offset wells using the **<** and **>** keys.

If necessary, the **←** and **→** arrow keys can be used to toggle the displayed reference well to any of the currently displayed offset wells. This allows the user to change the reference well without having to come out of the chart, open a different well and then open a new chart.

When **Centre on survey** is selected the **Show closest approach** option can also be selected, displaying a line between the reference and offset well and labelled with centre-to-centre distance between them at that point in the reference well.

The **Go to bottom of well** and **Go to top of well** will send centre the view at the bottom or top of the well, respectively.
