Whenever I place custom DataGroup wall items, why does the width and height of wall defaults to "0" ?
1. Check the DataGroup Validation to validate the DataGroup.2. Make sure the Wall_Application definition is attached and width and height of each item is defined.3. Finally, the most important step to check that causes height and width to be "0" is to check if the units command line is missing from the xml file or not. Exp: <Units master="mm" sub="mm"></Units>
