Is value a number or a string? [Drawing title with scale symbol based drawing scale]

adura — Thu, 15 Sep 2022 21:06:17 GMT

Hi to everyone,

I am designing a title object with "scale symbol" for drawings. I need <drawingscale> value for make this "scale symbol".

<drawingscale> is one of autotext. So, are autotexts number or string? Or not both?

If I can use <drawingscale> value as a number (or string) I can draw scale symbol. But I couldn't do that because -I guess- autotexts are not return a number or a string.

What can I do?

I am not sure how to explain this properly, but here goes.

Autotext values are nothing - neither string or number.

The <autotext> is just some kind of place-holder that can display the value of the autotext field, but does not actually convert the value into a usable string or number.

So you can display the value, but you can not use it.

Barry.

Hi,

It is possible by creating two variables :

AC_OriginalDrawingScale (Text) and AC_Magnification (Real number)

Here is the script of my object

!!!!!!!!Master script EPS = 0.0001 unID = 1 ech_pla = SPLIT (AC_OriginalDrawingScale, "%n:%n", num1,sep,val_ech_orig) dim_ech = 1 IF AC_Magnification > EPS THEN dim_ech = val_ech_orig / (AC_Magnification/100) ENDIF !!!!!!!!!!Script 2D long_esp = 1.00 nb_div = 5 ep_ech_plan = 0.002 hach_symb = 64 PEN SYMB_VIEW_PEN LINE2 0,0,(long_esp/dim_ech)* nb_div,0 HOTLINE2 0,0,(long_esp/dim_ech)* nb_div,0 LINE2 0, ep_ech_plan,(long_esp/dim_ech)* nb_div, ep_ech_plan LINE2 0, -ep_ech_plan,(long_esp/dim_ech)* nb_div, -ep_ech_plan HOTLINE2 0, ep_ech_plan,(long_esp/dim_ech)* nb_div, ep_ech_plan HOTLINE2 0, -ep_ech_plan,(long_esp/dim_ech)* nb_div, -ep_ech_plan FOR i=1 TO nb_div +1 LINE2 (long_esp/dim_ech)*(i-1), ep_ech_plan,(long_esp/dim_ech)*(i-1),-ep_ech_plan HOTLINE2 (long_esp/dim_ech)*(i-1), ep_ech_plan/dim_ech,(long_esp/dim_ech)*(i-1),-ep_ech_plan/dim_ech TEXT2 (long_esp/dim_ech)*(i-1),-ep_ech_plan, STR(long_esp*(i-1),1,0) dist_der_num = (STW(STR(long_esp*nb_div,1,0))* GLOB_SCALE/1000)/2 IF i = nb_div +1 THEN DEFINE STYLE "bb" pol_text,ht_text_symb,1,styl_text SET STYLE "bb" TEXT2 (long_esp/dim_ech)*(i-1)+dist_der_num,-ep_ech_plan, "m" ENDIF NEXT i SET FILL hach_symb FOR i=1 TO nb_div-1 STEP 2 POLY2 4, 2+4, (long_esp/dim_ech)*(i),0, (long_esp/dim_ech)*(i),ep_ech_plan, (long_esp/dim_ech)*(i+1),ep_ech_plan, (long_esp/dim_ech)*(i+1),0 NEXT i FOR i=2 TO nb_div-1 STEP 2 POLY2 4, 2+4, (long_esp/dim_ech)*(i),0, (long_esp/dim_ech)*(i),-ep_ech_plan, (long_esp/dim_ech)*(i+1),-ep_ech_plan, (long_esp/dim_ech)*(i+1),0 NEXT i FOR i=1 TO 10 STEP 2 POLY2 4, 2+4, ((long_esp/dim_ech)/10)*(i),0, ((long_esp/dim_ech)/10)*(i),-ep_ech_plan, ((long_esp/dim_ech)/10)*(i+1),-ep_ech_plan, ((long_esp/dim_ech)/10)*(i+1),0 NEXT i

@adura It looks like @Yves has probably given you a solution, but for reference there is also GLOB_SCALE which can be used in the drawing space to set the size of text and other objects to paper space sizes. It wouldn't be suitable for a title block referencing the drawing.

Thanks a lot for your reply/solution @Yves ... I will adapt your code to my own.

Thanks for your reply @DGSketcher.
I think GLOB_SCALE will not work here because the object will play on the layout.
