Displacement distance as @(7sin60)<75

[GHutch]

Is there any way to include a trig function in the displacment distance?
@(7sin60)<75 does not work, but it is what I would like to do.
I have to calculate it each time and type in something like the following:
@6.062178<75

Thanks in advance.

Try this:

@(* 7 (sin 60))<75

it should work ... if the angle is 60RADIANS
For degrees:

@(* 7 (sin (/ (* 60 PI) 180)))<75

I admit that it is pretty complicated for a beginner, you should read the help file for Lisp expression

I'm afraid that the OP had listed LT as his AutoCAD type, so AutoLISP expressions aren’t applicable.

An alternative solution is to use Excel to do the calculation and build the displacement string - use cells A1, A2 and A3 to fill your values and copy-paste the concatenated string to AutoCAD command prompt.

=CONCATENATE("@", ROUND(A1 * SIN(A2 * PI() / 180), 5), "<", A3)

Or another alternative is to use the Windows calculator, and again copy-paste the answer into the command line.

You can use quickcalc in AutoCAD transparently and insert with Apply.

thanks everyone

Yes, I was wondering whether LT had that facility.

The above expression is written in Excel. Is it correct?
Then how do you send this expression into cad? copy/paste?

That's true, it is a formula for Excel. I proposed that to help OP build desired expresion since on LT there is no AutoLISP available.

The method is indeed Copy/Paste - I already stated that into my post; just be careful to copy from cell, not from formula field.
