How best to get my box to draft

[carrieives]

I am creating a two piece box that will be injection molded. (the top and bottom will snap together.) Each half is a separate part. I initially created each half by extruding a rectangle. I then rounded the outer corners. For the bottom, I put a chamfer along the bottom edge and then rounded where the chamfer joins the box. I then shelled this part, added some cutouts and other features. I then realized that I needed to draft the part. I have tried going back and adding draft to the first feature, that messes up the chamfer and rounds. I thought that I could just add draft to the end, but I can't get that to work right either. Should I have modeled this a different way? What am I doing wrong?

Thanks,

I think I pictured your part from your description. Try putting your draft on before the rounds. Don't include your draft in the extrude but as a separate feature outside of the first feature.

A different way? I think we might need more information to say.

With injection moulded parts it is always an advantage to consider what effects the draft will have on the model from the very beginning, how it will affect the rounds, chamfers, lacation features etc. Trying to then add the draft at the end without planning it doesn't often work and dowhat Bart said about adding rounds after drafting.

Adding a draft feature right after my chamfer but before I rounded the edges of the chamfer worked.

Thanks.

That sort of thing is really hard to think of on a beautiful Saturday.
