Block's name to FIELD (based on existing lisp)

[tomjas]

This is fantastic! So easy to understand and modify!


I’ve added another variable ‘zvalue’ so for point coordinates you can decide to show X,Y,Z or only X,Y

If I can ask you for 2 last options, please:

1. Add code (in the same easy to understand and modify way) to ask user do define values for let say prec and suff, where asking for prec user have only options to choose (like drop down menu with numbers 0-4 but no chance to type different value- see graphics below). And for suff user can type anything or if left empty will be nil.
2. Add IF function- so let say for point coordinates I want ask user: “Show Z value?” and user have 2 options Yes and No. If Yes – variable zvalue will be 3, if No- zvalue will be nil.

Hopefully this is not too complicated...

This is excellent piece of work! Working perfectly, easy to understand for someone without lisp programming skills and easy to customise it to my needs!

THANK YOU!

Hi Lee Mac,

Final question about code:

when you are using:

(while (not (<= 0 (setq prec (cond ( (getint "\nSpecify Precision [0/1/2/3/4] <0> : ") ) ( 0 ))) 4))
    (princ "\n** Precision Must be Between 0 and 4 **")
  )

is there any way to show something like graphic below but still get value of selected number so I can imagine that part [0/1/2/3/4] must be edited but how to insert some text here when this is responsible for returning value?

Hi Lee Mac,

I have used the getint function prompt for an integer, hence the function accepts an integer input, not a string. You can quite easily alter the string prompt to display as you posted, but the entry would have still have to be a number.

I've just spent 2 days trying to work it out and I'm stuck

What I want to do is create a label with area value of selected hatch- so is a modification of lisp attached as a first one.

Lisp should be like that:

Specify Precision: <0>
1
2

Specify Conversion Factor: <1>
0.0001 (m2 ->ha)
0.000001 (m2->km2)

And another tricky part here with suffix. If user selected 1 for conversion factor, suffix should be m2. If 0.0001- suffix ha, 0.000001- suffix km2. Don't want to ask user about suffix- just depends with conversion factor, suffix will be there.

I'm really fed up- I've sorted one thing, other is not working... Seems to be really simple, but after 2 days...

Can you help, please?

[Lee Mac]

Something like this seems more intuitive to me:

Hi Lee,

This is magic and you're right- this is more intuitive

The only small problem is when asked for precision (is 0 set as default because black dot is next to 0?) and user hit Enter- there is a error: ** Error: bad argument type: stringp 0 **
Is working fine when user is clicking 0 from the list.

Is there any easy way to fix it, please?

Once again- thank you very much. This is far better than I expected....

[Lee Mac]

Sorry Tom, I rushed it a bit and wrote it too quickly - I must've got the data types mixed up, a minor fix and code is now updated, please try it.

Lee

[tomjas]

Lee- you are officially my own favorite Lisp Guru!

Massive thank you for that!

If you are interested – I’ve posted new thread. This time something challenging
