If you are trying to create a mitered flange, then have a look at this video. The steps have not changed since they introduced this feature.

Let me know if you need an example in SolidWorks and I can make one up and upload it here. Also if you have a more detailed picture or description of the flange, that may help to.

Open your SW, go to help and type "miter flange", it's all explained ;)
