Hi everybody,
I found this sheet metal punch on the internet, it is a press rib.
I found it very useful for me but I don't know why I can´t modify it parameters.
I tried to edit the iFeature but it seems to be a problem.
I would like to change the length, width and height.
Does anyone know how to fix this or dows anyone know a different way to model this punch?

Thanks a lot

Hugo
