In search of a little help. I have created a skeleton with the geometry of my sheetmetal parts. These part parameters are linked to an excel spreadsheet. I have derived the parts into an assembly, gave them a face and flanges. Here is the question - some of the parts I want to pattern (array) using parameters. I can get this to work in the skeleton but it will not transfer to a modeled part in the assembly. Inventor will not let me pattern the part in the assembly. What am I doing wrong?
