sheet metal cone

[egghead]

I am trying to generate a cone both a normal one and a cone with the top cut off, can anyone tell me how to do this and be able to generate a flat pattern for it so i can define the sheet size required.

I have looked at this but have not been able to create a cone and then a flat pattern from it.

I revolved the sketch around to generate the cone. fine the cone created Ok but when i click on the flat pattern button it just reorientates the cone but doesnt generate a flat pattern.

Try clicking on the inside or outside face first and then with it selected hit the Flat Pattern.

I have tried that but still no joy.

You need to create a gap in the revolution for it to flatten. Inventor will not deform material in this way.

edit: Oops, I saw you did create a gap. The error in this example is that your revolution sketch does not follow the rules you have for your Sheet Metal Styles. The thickness of the wall has to match your thickness in your current style. After I fixed this it worked fine. Message was edited by: mark.flayler

I would recommend this book
http://ascented.com/courseware_Inventor_2008_Sheet_Metal.htm
or one from AOTC
or Training from your VAR

(In the classroom we fold up paper - thus the .004" sheet thickness.)

Have a look at the attachment.

To create a flat pattern you have to select a surface (inner or outer
conical surface), clicking on it, before to click on the flat pattern
button.
