Label that displays another object's parameter

[Melissa Fleming]

Hi there!

I’m trying to create a label that will display the area of a wall and the length of a wall and also the calculated average wall height (area/length). This is to be use for labelling walls on boundaries. I’ve attached a screen grab of a text label indicating what I’m trying to achieve.

So far, I’ve placed the “wall tiles” object (attached) that I found in another forum topic (thanks) and have been trying to reference the parameter “calcA” in a label. I’ve used the request command in the master script like this:
requestedValue=””
n = REQUEST(“ASSOCLP_PARVALUE”, “calcA”, DUMMY_name_index, type, DUMMY_flags, DUMMY_dim1, DUMMY_dim2, requestedValue)
Then I have written the following text2 command in the 2D script:
text2 0,0, requestedValue

That all works fine – producing a simple label that displays the wall area alone. BUT when I try and set up a paragraph so that I can include formatting and the leader text of “AREA OF WALL = ” before the displayed requestedValue, the best that I get is a label arrow with a dot on the end where the text should be. I haven’t even tried working on the length and average height calculations yet!! This is the script I’ve used for the paragraph, followed by textblock & richtext commands:

paragraph “label_para” LABEL_TEXT_ALIGN, ! name alignment
0, ! firstline_indent
0, ! left_indent
0, ! right_indent
LABEL_TEXT_LEADING ! line_spacing
pen LABEL_TEXT_PEN
style “mySampleStyle”
“AREA OF WALL = “+””+requestedValue
endparagraph

As you can probably tell, I’ve not used the request command before and am still learning paragraphs. Any help you can offer would be greatly appreciated.

It seems your calculated area is a number, which you can’t add to a string. You can create a string from a number with the STR function.

Thanks Gergely,
Can you provide me with a direction or a web link on how to set up the string function and where to put it in the script? I get a bit lost with strings!

I understand your suggestion Gergely, but I just can’t figure it out.
I think this one is over my head! Thanks though

I expect AC22’s calculated element properties will do this, with the standard labels.
