Who cares? The second one is not the format given in the API dictionary. Use the first one.

The FILE works if you run the code from the .rb file loading. The way you have it set should work if the file 'Price_lookup.csv' is in the same folder as the .rb... You code has an error: csv_text = File.read('Price_lookup.csv') should be say csv_text = IO.read(csvfile) giving you an array of the lines. I'm not sure about how you are parsing the file data you read in... BUT once you successfully get the data in, then temporarily 'output' it to the opened Ruby Console to check it's as you expect, with: puts csv_text and showing hidden characters like \n etc p csv_text added in after the data is read-in...

Hope this explains my requirement a little better. I have a sunroom comprised of many groups: corner post, floor channel, door, window etc. I want the user to select their sunroom color by clicking the model. In order to do this I need to gather all the sunroom groups into a parent group where I will use the onClick function to change the Material attribute. I expect the Material change will automatically cascade to the sub-groups but if not I can easily set the Material of the sub-groups to something like=Parent!Material The question is how do I wrap all of my groups into this parent group? Thom Thom thank you for the advice regarding start opertaion, but I do not need undo for this model, the user is starting with a blank canvas and will simply delete top level group if they have to start over
