====== Externals ======

At this stage, you should have the general shape of your vehicle.  You should have a modified Volume, Area and Linear values.  Now it's time to put the hull together.

There are two primary external features you will have to worry about:  [[drawingboard:externals:endostructure|Endostructure]] and [[drawingboard:externals:armour|Armour]].

<WRAP info>
From this point forward, everything added to your vehicle will accumulate both mass and volume.  Your mass was chosen right at the beginning;  your goal should be to use up every gram of that mass.  You don't need to worry about filling all your volume, but if you want to be super-efficient, and you have lots of volume left over, you can go back and fiddle with it.

===== Mass, Volume and Cost =====

Mass is generally given in kilograms or in tonnes, and will be indicated as such.  For those from the United States, there are 1,000 kilograms in a tonne.  Remember to convert as needed.  

Volume will either be given in liters or in cubic meters.  There are 1,000 liters in a cubic meter, so again, remember to convert.

Cost is given in imaginary currency values, represented by the symbol **₠**.  One ₠ is about enough to buy a loaf of bread.
