link a predefined field to an object

hi

im working with fields connected to objects for area calculations,

each time i need a new field i have to do the same initial operation over and over (Field > Object >Select>Additional Formatting etc)

i want to set a predefined field so all i need to do is the select the object which i want to link to.

how can i do it?

Thanks

Have you checked out LeeMac?

If not, why not?

yaa im a big fan of LEE, but it seems like i miss that one

Thanks

I modified his code a bit to add macros for labeling in my CUI. Length, square feet, square yards, and acreage. Out of respect I wouldn't post it without his permission. A respectable amount of my code was downloaded from http://www.lee-mac.com/

hi

i never been a math genius but autocad got confused here (or me)

290.10+3.84=293.94 (sorry for the mistake in the attached image)

but the preview shows 674.58

?

The 3.84 is for some reason being read as 384, and that is being added to 290.1.

I haven't delved into the field expression, but am guessing that the units format in your field may be the problem.

Do you have any Additional Formatting specified?

no.

ive attached a sample dwg

field-prob.dwg

im the sample i\ve set the point to read 290.10 ,

ive offset it 50 units up,

i expect it to now read 290.60

no.

If you subtract 290.1 from 290.6, you will see that the difference is 0.5 mms, not 50mms, doesn't seem very surprising to me?

If the units you are working in is centimeters, you can't input a measurement in meters into a formula and expect Autocad to work it out, you will need to add some additional math in the formula to make the units the same type.

field-prob.dwg

The drawing units are mms, and yes, I agree steven-g, glad you spoke up, as per my conjecture in the first response.

On Lee's website, in his description of the capabilities of the lisp, he describes the steps needed to define or alter field units, in conjunction with the lisp to which I linked in my earlier post.

It would be helpfull to see the file, that had the "wrong" answer shown in post #5 it certainly looks like an addition format problem.

Thank you guys

o....by the way can i set different bg color to the field?

Nope, you can turn it off fielddisplay=0 and if you use mtext to create the field you can set a background color in mtext

Thanks. i want to apply a mask to all fields, and when its time to plot i want to remove masks. how can i filter in fields?

actually i play around with that thinking about the easiest way to unique the fields with a style,

i actually find that the MLeader style can be used, in the style definition just set the leader type to none, in the Content insert a field,

and set the Frame Text option on, when its time to plot you just need to uncheck it

still interested to get your thought and methods

Thanks

Nicely answered Steven, and spot on.

I don't have the file referenced in post #5, but right again, which as students of history, we have all come to expect from you!

hi. is there a trick to regenerate field upon move?

hi

i want my field to display its own Y value,

setting the same procedure >insert > field>object>select) wont let me to select itself

why?

What type of object is it?
