How to calculate batter

How to calculate batter

How to calculate batter

(OP)
Is there any simple formula to calculate batter of a structure such as 1 to 10 to arrive at a degree off vertical?

RE: How to calculate batter

aweysham, if a batter is what I think it is, a sloping surface, and you have some overall dimensions, some simple triangle trigonometry will give you any angle. Is that what you had in mind?

RE: How to calculate batter

aweysham,

I use a degree-calculater in the www, or Excel.
In ACAD there's IMHO no way. I would draw the slope in % and trim the lines...

the ArcTan [inverse tangent] of 1/10 will give you 5.7106 degrees [degrees from vertical]

Draw it 1 in 10, then get and angular dimension from AutoCAD?

Or, knowing that the tangent of the angle is equal to the rise divided by the run, calculate it.  AutoCAD understands tangents and the inverse.  On the command line, type CAL [space] then atan(1/20) [ENTER].  AutoCAD tells you the angle in the current units.

Hi IFRs,
thanks for the calculator tip. ACAD can more than "+" and "-" wink
But I can't use it while drawing a line...?
_line -> first point -> < 'cal ... doesn't work

Many thanks to "Ipseifert" & "IFRs" for their answer. Yes I arrived at 5.7106 but by the hard way. I figured their must be a formula somewhere. I tried IFRs way but do not get an answer when I query Cad. I typed cal and space, then I get the prompt, "Expression". so i typed in atan(1/10) but get nothing. I finally got my platform dwg with the correct batter 1/10 but was looking for simple way next time I make one up for planning purposes and the batter may be different.
thanks,

Try this: Line 0,0 @1,-10

RE: How to calculate batter

Try cal...
atan(1/10.0)   10:1 batter
atan(1/20.0)   20:1 batter
