Autodesk Inventor - Part I - Skeleton Modeling - Sheet Metal & Frame Generator

In the first Part of this Autodesk Inventor video I show a workflow called Skeleton Modeling, to create a Sheet Metal Cowl, supported by a frame. The Frame is created using Frame Generator within Autodesk Inventor. In this release of Autodesk Inventor some great new stuff is added to Frame Generator. Skeleton Modeling is a very powerfull way to create assemblies in Autodesk Inventor. You can start very simple in a single Autodesk Inventor Part, with just a couple of sketches and surfaces. Frame Generator in Autodesk Inventor is based on Skeleton Modeling aswell.
This first Part of the video shows how I create the Skeleton. In the second part I will create the Cowl Assembly. The Skeleton Part will control the final Autodesk Inventor Assembly parametric. With this technique there are no assembly constraints needed and the parts created from the first ‘reference’ Part are very stable and will accept almost every parametric change made to the reference part. This makes it a great workflow for Sheet Metal and Frame modeling in Autodesk Inventor.
The Cowl shown in this video can be changed to almost any dimension. If you have any questions, let me know in a comment.

when i change dimension to the sketch , my surfaces doesnt change.only the lines change?does anybody know why?
