Displacement distance as @(7sin60)<75

Is there any way to include a trig function in the displacment distance?

@(7sin60)

I have to calculate it each time and type in something like the following:

@6.062178

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.

Is the distance you require one that will change frequently? Is it in anyway related to the scale of the drawing?

 

I just discovered that you can use 'spacetrans command within the displacement function. This may not be helpful to you, but it does keep the hope of a transparent calculator alive. I only learned about 'spacetrans command last month, after 7 years of CAD. Perhaps there are others that can be used in this way? I am yet to find a comprehensive list.

Okay, so Spacetrans may not be helpful to you at all.

But the ' used before a command to use that command transparently inside another command may be of more use.

You can use a command line calculator function called CAL. I have not had time to get the 7sin60

Command: M MOVE

Select objects: 1 found

Select objects:

Specify base point or [Displacement] : D

Specify displacement : 'CAL

>>>> Expression: SIN(60)

Resuming MOVE command.

Specify displacement : 0.86602540378444

What is spacetrans command?

Spacetrans outputs the model space distance of a paperspace distance input by the user.

It is particularly good for setting standard text heights in all different scales.
