ShipBuilder V3.0This is a spreadsheet built to aid in the desing of realistic spacecraft. It was origianlly created for RocketversUsing the constants page, you can create almost any kind of ship you want. About 75% of the numbers usedThis sheet is designed to work with BattleTrack 4, which I am working on. It's what the export stuff will be for

Notes:

The weapon's power hasn't been figured into the itemized power draw. Whatever you want should go underThe way structure mass is calculated leaves the sheet vulnerable to errors. If you happen to get any sort of inI've added a button on "Bulk Components" which clears and resets the error. If the error persists, then the imyou've cleared the error. You may have to enable iterations to make the structure work. Do what excel says.Some of the numbers may seem funny. Also, a lot of the boxes are more for me than you. If the inputs are riThe masses on the ship overview might take some explaining.Dry Tankless Mass: The mass of the ship without tanks or consumables.Dry T Warning: If the mass ratios on both the NTR and electric are close to 2, bad things could happen.

Bad. The mass numbers will be negative. This is not a bug, it's the math. The ship can't be builth electric and NTR assume they burn the entire time with the other loaded. You should get more.
