https://forums.autodesk.com/t5/inventor-forum/sheet-metal-extens-help-iv-2016/m-p/5620401#M377122 <P>I just upgraded from IV 2010 to 2016.&nbsp; I am trying to get the parts list to read the thickness, width and length of sheet metal parts.&nbsp; In the past we have used a add in program that worked really nice.&nbsp; It would give us the thickness in gauge (i.e. 11 ga. not 1/8" or .1196"), the width of the flattened part and the length of the flattened part. Any time that the part would change the parts list would automatically change.&nbsp;&nbsp;My add in program can't be used with IV 2016.&nbsp; I have been doing some reading in this forum trying to get an answer.&nbsp; It would now appear that IV 2016 does not need an add in and all that may be required is to insert some custom i properties. However I must be doing something wrong as I keep getting incompatible units in my parts list. I have typed Width for the name and &lt;SHEET METAL WIDTH&gt; in the value selected apply and it doesn't work. How can I achieve the attached with IV 2016 without manually typing information and that will update automatically? Thanks.</P> Mon, 04 May 2015 19:41:56 GMT scoopthepoop2000 2015-05-04T19:41:56Z
