gdl unit of text

lmcardoso

Hi,

 

I am a newbie in coding. sometimes i try to cook something but i end up spoiling the broth. i spent the last 30min reading the gdl editor on strings and integers but that thing is way to complex for me.

 

I am trying to change the units of the value of AxB but i cant seem to find it.

this is my object and now the area, which is no more than AxB is in millimiter but i want it in meters

this is my code

 

set line_type ln01
pen pen01
fill fill01
poly2_b{5} 5, 3, 0, pen01, pen02, pen03,
0, 0, 1, 0, 0, 1, 0,
0, 0, 1,
A, 0, 1,
A, B, 1,
0, B, 1,
0, 0, 1


define style{2} "AC_STYLE_1" "Arial", txsz , 0

paragraph "AC_PRG_7" 2, 0, 0, 0, 1
pen 1
set style "AC_STYLE_1"
""+"< "+STR(1000*A,1,0)+" >"
endparagraph
textblock "AC_TEXTBLOCK_7" 0, 5, 0, 1, 1, 1,
"AC_PRG_7"
richtext2 A/2, .2, "AC_TEXTBLOCK_7"




paragraph "AC_PRG_8" 2, 0, 0, 0, 1

""+"< "+STR(1000*B,1,0)+" >"
endparagraph
textblock "AC_TEXTBLOCK_8" 0, 5, 90, 1, 1, 1,
"AC_PRG_8"
richtext2 0.2, B/2, "AC_TEXTBLOCK_8"

IF txt01=1 THEN
DEFINE STYLE TEXT_1 Arial, txsz , 5 , 0
SET STYLE TEXT_1
TEXT2 A/2, B/2, ""+STR(1*A*B,1,0)+"m2"
ENDIF

 

Can anyone help me please?

@lmcardoso metric GDL coding is in meters by default, so you text should be...

TEXT2 A/2, B/2, "" + STR((A * B), 8, 3) + "m2"

you need to use STR{2} so you can set what you are after.

 

also  you dont need the "set" for line_type or style to work.

thanks seneca, but for me that is still unknow to me.

 

i tried TEXT2 A/2, B/2, ""+STR{2}(1*A*Bsqm,1,0)+"m2" 

 

but it doesnt work...

so maybe i am miss understanding, but if you change the code to

 

TEXT2 A/2, B/2, ""+STR(1000*(A*B),1,0)+"m2"

does this not get what you want?

i tried but that no it doesnt solve the problem. I guess its the units that are not right

 

what it should appear is 10,8m2 instead of 10800.

 

on your left a fil showing the area and on the right my object

okay try this

 

TEXT2 A/2, B/2, ""+STR("%.3m",(A*B))+"m2"

Another way, with reading the working units of the project

format_string = "%.0" !Defult
n = REQUEST ("Area_dimension", "", format_string)

!! Or
!!n = REQUEST ("Calc_area_unit", "", format_string)

_stUnit = "m"

if strstr (format_string, "mm") & not(_bUnitIsFound) then
	_stUnit 	= " mm"
	_bUnitIsFound  	= 1
endif
if strstr (format_string, "cm") & not(_bUnitIsFound) then
	_stUnit 	= " cm"
	_bUnitIsFound  	= 1
endif
if strstr (format_string, "m") & not(_bUnitIsFound)  then
	_stUnit 	= " m"
	_bUnitIsFound  	= 1
endif
if strstr (format_string, "f") & not(_bUnitIsFound) then
	_stUnit 	= " ft"
	_bUnitIsFound  	= 1
endif
if strstr (format_string, "i") & not(_bUnitIsFound) then
	_stUnit 	= " inch"
	_bUnitIsFound  	= 1
endif

_stUnit = _stUnit + "²"

area_ = A * B

area_txt = str(format_string, area_) + _stUnit

This is a great answer if you're trying to accommodate multiple different disciplines!
