Bismarck Superstructure [Deleted]

darkapollo submitted a new resource:

Bismarck Superstructure - Ready to print, multiple part, little support needed.

Just noticed a major flaw with the super structure. I will be repairing and uploading a fixed version.

 

darkapollo updated Bismarck Superstructure with a new update entry:

Update to Fore L1

Excellent. I was waiting for the McFadden superstructure to be updated to a Tirpitz version. Thank you so much!!

 

The Tirpitz had a slightly different superstructure.
The rear range finders were domed not exposed. The tower radar was substantially larger.
The bridge between the tower and the funnel was removed or not built.
The funnel cap was enlarged.
The boat cranes were inboard and up on the L1 deck not the weather deck.
The L1 deck was extended to slightly beyond the hull to support the cranes and tertiary guns.

Modifications easy enough to make but there are visible and obvious differences.

 

Interesting. I was not aware that the funnel cap was enlarged. I am about to download the files . Can't print them yet as I have new nozzles on order for my printer.

 

Also there were additional AA mounts added to Tirpitz.

A 10,000’ view of the differences:

Easy enough changes to make to the files if one was so inclined. I may, if I build a Tirpitz.
Also the Tirpitz was longer as the Bismarck did not have the Atlantic bow as launched, it was added after sea trials. Tirpitz was built with it, adding almost 9’ to her length.

 

Yes I knew about the length differences and mostly everything else . 9 ft would be correct as Bjsmarck's overall length was measured without the Atlantic bow just the straight stem prior to launch. The engine plant was also longer in Tirpitz resulting in a more tapered stern which was a little longer than Bismarck's .

My nozzles arrived so I am going to install them and hopefully get the Arizona super structure started again .

 

just wondering but i opened the files for the super structure and measured in fusion 360 and for soem reason the measured distance is massive. i opened the level 3 file and just wanted to see hwo wide it was and fusion is saying its 33 inches wide.. just wondering if its me or something im doing wrong. most likely somethign im doing but figured id ask... GREAT work btw though.. look forward to printing this... will have to look into what you mentioned for tirpitz as i have that ship aswell.

 

Try changing your units to mm before importing.

 

Gonna second what Beaver said, set Fusion to default to mm measurements instead of inches. In Cura, when I was first learning CAD software, trying to slice my drawings ended up getting some teeny little things, after I realized it thought my inches I'd drawn in Fusion were millimeters, and I had to rescale everything. It sounds like you're having the reverse problem.

Alternatively, if you still wanna measure in inches by default in Fusion, you could use the scale function and set the scale factor to 1÷25.4, which should be the scale conversion from inches to millimeter size. That would probably "un-convert" everything back down to the original drawing sizes.

 

Once imported you should be able to change the units back to inches. Not 100% on that but give it a try?

 

Do I have to use Fusion. Ca I use Cura or Simply 3D?

 

The files are in mm so there is no need to convert if that is already your default in your slicers.

100% you’re fusion defaults are in inches. I never use imperial units with engineering and CAD. STL files are really only a list of cartesian triangle points with no other reference. So if your defaults are inches, Fusion is going to read the points and associate them to an inch grid.
What size is your printer bed? Everything has been meticulously cut to fit on a 200x200 square bed which is the most common small size for an FDM.

 

I set the default to MM and im still getting enormous structure measurements. I have an ender 5 so the print area isnt the issue. I was just looking at the details before sending to cura. guess i was wantign to see it all fit together and see dimenions before printing

 

Did some digging, might've figured it out. I tried converting and comparing to a Cura test render, and I was getting strange size discrepancies. I learned one thing; Fusion doesn't like opening .stl files.

Instead, import them using the Insert dropdown and select the target piece you want to insert. I used the Level3 Citidel as reference.

Make sure you're setting your unit type to millimeters. I centered the object and then moved it to ground, just to center it on my origin plane.

I measured it (I'm defaulted to inches, learned CAD that way in highschool) and traced it with a sketch and showed measurements.

I compared it to my print bed in Cura. I print on a standard Ender 3, the print bed is roughly a 9 1/4" square bed, and the print takes up roughly 1/3 of the bed area from top to bottom when I'm eyeballing it, so I'm fairly certain it's the right size.

Not very scientific, but that's what I found works. If you're just printing, Cura takes them with no scaling required and no questions asked. Hope this helps.

 

Fridge came up with a solution. Not sure why it makes any difference but i did inport as a mesh and it works rather than just opening the stl. Attached is a dimension of the same file if just opened in fusion

 

So are the files for the front and rear range finders in this resource because I wasn’t able to find them while trying to download

hey i was wondering were you planning on adding the Barbettes B&C from the Mcfadden in the near future? ive hopelessly tried recreating them but haven't really been able to learn Tinkercad
