Sum Text Strings to Text Field...

January 12, 2010

Good Code Gile, thanks,

Agreed...

I think I know where is a problem. First routine (fArea.vlx) creates labels with field and text 'm2' or whatever user will type. And this 'm2' is not a suffix- is a text. So if somebody can create routine which will do the same (measure area of selected object) with proper suffix (maybe asking user to define one)- then the last code from gile will work perfectly, reading precission, format, suffix). I need to start looking for some lsp tutorials... you guys are doing magic!

good! we have another recruit..

January 12, 2010

Haha not a chance mate...

On a side note... Wiz, could you collaborate to see if we can get this working? (just for academia)

(vlax-for obj (setq ss (vla-Get-ActiveSelectionSet doc))
       (or First (setq First obj))
       (setq FldStr
        (strcat FldStr
          "%<\\AcDiesel $(if,$(eq, m2,$(substr,%<\\AcObjProp Object(%<\\_ObjId "  (itoa (vla-get-ObjectId Obj))
                ">%).TextString>%,$(-,$(strlen,%<\\AcObjProp Object(%<\\_ObjId "  (itoa (vla-get-ObjectId Obj))
              ">%).TextString>%),2))),$(substr,%<\\AcObjProp Object(%<\\_ObjId "  (itoa (vla-get-ObjectId Obj))
              ">%).TextString>%,1,$(-,$(strlen,%<\\AcObjProp Object(%<\\_ObjId "  (itoa (vla-get-ObjectId Obj))
                        ">%).TextString>%),2)),%<\\AcObjProp Object(%<\\_ObjId "  (itoa (vla-get-ObjectId Obj))
                ">%\).TextString>%\)>%" " +")))

working but will not be updating the new total area when changed because of the if statement inside diesel.

January 12, 2010

Am I right in saying that you only changed the quotation marks in m2?

January 12, 2010

i think last line also lee, be back tomorrow..'-)

Good morning!

I can see that you couldn’t sleep.

Thank you very much for your effort. I’m really appreciating it!

Wizman:

Thank you for Afield code!

Is it possible to (AField):

-Create new text label, rather than selecting existing text or attribute (in this case we need to ask user for start point, text height and rotation angle). Or maybe ask user to set the text height and rotation angle for the whole routine only once, and then ask user only for start point of new label.

-Match properties of selected object – layer, colour. If they will be on the same layer as a selected object, than I can easily isolate them and change ie. Text style

-Create like a setup option where user can specify suffix, multiplication factor (if they have a dwg in m2 but want areas in ha), display precision (I can’t see where to change this in code) and maybe as I ask in first bullet point: text height and rotation angle.

Code created by gile:

- can new label match the layer and colour of the last selected object too

I know I’m asking for a lot, but:

-I’m working with some ‘cad users’, and most of them don’t know how to set colour of the object to ‘by layer’, so you can imagine if I’ll ask them to use Quick Select tool to isolate text and change properties…

-You guys are the first ones who is doing this and publishing in web (I’ve spent 7h searching for this sort of lsp- what I’m going to put in my timesheet??)

-is a challenging task

-you guys are great

WOW

Working great!

Can you just point me what needs to be changed in code to set the accuracy, please?

Previously was quite simple (setq Units 2 Prec 3) but since you just 'jump' to 'next' level I have no idea. Or maybe user can define accuracy ?

once again thanks

I update the code above, now with precision..'-)

This is great Lee as you don't have to type text height, rotation and suffix each time (or pressing enters)- set values once and then selecting object and placing label = great!!!

I've tried change the wiz code to force user to define precision without any success

Can you add option to set the precission on the beginig as you did for text height, rotation and suffix, please?

And I'm in heaven

THANKS

All sorted!

I need to change gile code to match layer properties of last selected object, and find the way of asking for conversion factor (in your code) and then I can explain how to use it to our 'cad users'. Or maybe adding conversion factor option is a 10sec job for you and maybe 5sec job to change gile code to match layer+layer colour of last selected object? PLEASE

And one additional question: is it my task a challenging one? or you guys are doing more complicated tasks before going to bed each day?

thanks

And one additional question: is it my task a challenging one? or you guys are doing more complicated tasks before going to bed each day?

To be honest, no, this part is not too difficult, the field code does all the work, but I just like to code it in more interesting ways

and find the way of asking for conversion factor (in your code)

What do you mean by this?

January 13, 2010

I meant another option to ask user for conversion factor as you asking for text height, rotation, angle, units type, precision...

ie. dwg is in meters but they want labels in ha, so changing suffix is simple (now ) but if you will set the conversion factor to 0.0001, then label will return area in hectares.

If you will insert field, fields category: objects, select object, area, format, precision, than there is that extra button: Additional Format:

and you can set the conversion factor there...
