I am experiencing a problem in 2013. In partbuilder, I am trying to add wall thicknesses to the simple cylinder. I was able to add options for inside diameter and set floor thickness to a list and add options for that, but when I try to set wall thickness to list instead of constant, I get an error in the value menu. Everything disappears and in red at the bottom, I get a message about an error in calculations. I even tried temporarily deleting the WTh from any calculations, but I still got the error. I have had no problems doing this in 2011 or 2009. Does anyone have any suggestions? Thanks!!
It seems that you are using the product itself rather than API, I will ask moderator to move it to product board to get more response.
