DIK has it right. You can also enable alternate units and have both imperial and SI displayed.
Type DDIM and edit the dimstyle you are using.
You can also create a new DimStyle with the factors you want and apply that to your dimensions
API 650 petroleum storage double wall tanks are typical where real estate is not available and the exterior tank serves as containment in lieu of a bund or dike area. For instance for gasoline or jet fuel storage in cities fed by pipeline and emptied by trucks. These tank systems are both...
Can you inject a cutting agent to make the mixture flow easily?
In any case your low suction nozzle elevation will be based on the pump used and it's ability to work with viscous materials.
Pentane is gennerally not corrosive to the steels used in API 650 type aboveground storage tanks. However, I'd add 1/16" minimum becasue the tank inside will be exposed to air as you fill and empty, and most air contains some moisture content which can condense on the tank and fixed roof. If...
There are possibly commercial and or regulatory advantages to having a smaller tank rather than saying you are limiting the liquid level.
The methodology is basically remove 3 meters off the top, add an API suppored cone roof.
It's not rocket science, just basic tank work.
Get three bids from...
Add the specified corrosion allowance to everything that will get wet with product - things like the inside of the tank shell, all sides of the fixed roof support columns, shell nozzle pipes, the underside of the floating roof, etc.
Stainless steel self drilling screws are often SS 410 and will rust. This will look badly as well as not doing their job. If you drill holes, you can find SS self tapping screws that are austenitic SS and are much less apt to rust. Neither will hold well in the 18 gauge substrate, perhaps...
Yuu can include a small ring of liquid pressure into your ringwall design, it will add some moment, more if the ringwall is side inside. Don't forget that as the soils are compressed vertically, they try to expand horizontally, inducing tension in the ringwall.
9.5Z12 is a "Z" shape 9 1/2" tall made from 12 gauge material

31.8 15/16 I think is 31'-8 15/16" long
The abbriviations are more of a mystery but a girt manufacturer might know or they may be clarified on the drawing
I'm sure others in this forum will help much...
If you are in Model Space, rotate it using the rotate command.
If you want to rotate it ouf of the plane of the current UCS:
on the command line UCSFOLLOW 1, then use the UCS command like UCS X 90 to change what you see, then rotate the object.
use UCS W to change your perepctive to the default...
If you are using XRef that is, you normall get whatever is in model space, which is why only the object goes in model space and not dimensions, titleblock, notes, etc
You import the part. You get the part, not the orientation. It comes in as it was originally drawn. Once you have it, you can rotate it in Model space to the desired orientation or manipulate the viewport's UCS to show what you want.
