Extracting Max Height and Area of Symbols

1) What is the error message on s_prop?
2) Have you isolated which line the error is occuring on?
3) Is "prop" evaluating to something other than a string?
4) The skill doc doesn't show the comma for the sprintf command syntax (but I don't think this is a problem).

foreach( prop_pair proplist
prop_key = symbolToString( car( prop_pair))
prop_val = cadr( prop_pair)
if( prop_key == "PACKAGE_HEIGHT_MAX" then



the important thing to know here is properties are stored as key-value pairs within proplist AND
the key isn't a STRING but rather a symbol so you need to convert it b4 doing the comparison.

several tips;
1) axlDBGetProperties(shape "allegro") will return a list of name value pairs instead of using shape->prop->??
- also allows for high-level property filtering
2) It is more efficient to compare symbols so either define PACKAGE_HEIGHT_MAX as a symbol or convert it to a symbol
sym = makeSymbol("PACKAGE_HEIGHT_MAX")
Alternatively a comparision using a symbol: if( prop_key == 'PACKAGE_HEIGHT_MAX
3) If you are just trying to get a single property value off a dbid then you can do
value = shape->prop->PACKAGE_HEIGHT_MAX
if property is not defined then the value is nil

Hi All,

Thanks for the help... Here is a working update... Please provide any further feedback on ways to make this more efficient...

Hi All,

My apology for the formatting... Here is an attached formatted version...
