i sure could use some help in getting a accurete volume count.

i have put the design here so you can view it.
i would thank you in advance for any help you can give.

Lemme see what you have and what I can do for you.
Mind ye, do you want this HG/TNE/ or T-20?
Please specify.
The first two I can do for you pretty quick. The latter I'll muddle thru after "rough drafting her out."

Generally when doing CT/MT deckplans, I simply draw the interior components where they would properly fit inside the general shape of the vessel I conceptualized. All remaining space is Fuel, provided it "feels" like it leaves adequate volume to complete the ship correctly.
I have 'precisely' calculated the volumes for other deckplans but they were never as complex a shape as your example.
If you want an accurate (not precise) idea of what you have there you'll need to break the drawing down into a set of individually simpler polyhedra and then calculate the volume for each one and sum the total.
Without a true scale and grid on the drawing you have posted there it would be difficult to make that volumetic calculation, and since it is in Word, I didn't want to go to all the trouble for that.... Sorry.
Good Luck!

I have a highly technical way of assessing total volume of complicated shapes like this -
i) Look at the thing, mentally you put it in a rectagular box that just fit sidewards/length,
ii) Mixmaster the whole thing, and let the volume sludge down so that it fills the box
iii) Eye level the height of the resulting sludge. You now have a simple box to do a vulme calculation
Looking at your plan, if it's 5 stories high, I reckon it would pulp to arround 1 1/2 stories.
So 300ft long * 100ft wide * 20ft high -> 600,000cubic feet. Of this only 80% of the interior is usable (it's streamlined) but the whole thing contributes to volume. I make that to be 1200 tons. A little big, but well within bounds for an eyeball result.
If you want an accurate figure, then either chop it up into sections you can measure (ie put lots of numbers for the angles and edge lengths) or make one out of something (ie plasticine) and imerse it in water to give you an accurate displacement volume.
If you do the second of these, I would recommend you do it to scale rather than full size - but full size would have a variety of addition benefits so it can't be discounted (Live action RPGs onboard a full scale frigate). Plasticine probably isn;t the best idea for a 5 story high self supporting structure - but what do I know.

The Difference between Practise and Theory is bigger in Practise than it is in theory

Okay, I knocked together a basic block model from the plans you drew
and used MAX's measure tool to get the volume.
You can see that the shape has a volume of approximately 20,000
kilolitres or cubic metres.
This breaks down as 1481.5 Traveller Dtons or 2963 squares on a 1.5
metre grid. This makes it pretty much a 1500 Dton ship.
As this data is extrapolated from the already streamlined model then you could probably assume this is the volume after the 20% for streamlining is removed, making the ship closer to 1900 dTons - (1500 = 80% of 1875)

i would like to thank you guys for taking time to look at this design.
i put down on the plans that it was 1.5 meters per square.
i have already hacked it to pieces.
the front arrowhead was by far the hardest to figure,as with all the different angles it has.
i guestimated the arrowhead front at aroung 510
the docking collar at 83
the narrow neck at 161
the aft end figures 493
all total
510
83
161
493
---
1247 dtons
i figured that 1250 dtons with only 80% usage would get me a 1000 dtons to work with.
so i went with that, fudging as i go.
i want to thank you crow for the great rendering, i wish i had equipment like that.
i have actually made deckplans for this ship useing the 1000dtons figure.
i wish i could post them with something other than word.
thanks again for all your help.
