Hello all,

I have tried everything I can think of and done a whole lot of googling but can't figure out how to apply a draft to the part I am working on. The problem draft (8) is the last feature.

Any tips would be appreciated, thanks

    Fillet 2 and Fillet 4 are interacting it a very weird way (see highlighted edges). If you have very simple shapes, applying draft after filleting with "reapply fillets" will work, but in a complex situation like this, it's bound to fail.



    It's usually much better to apply draft earlier in the process and add those smaller fillets later.

    There are also many things "wrong" with this model e.g. very first sketch has overlapping geometry, no tangency in Sketch4, 2 transforms and a delete part to correct a mistake, 80 features, etc. This all results in bad geometry which will make adding draft and fillets much harder. The art to a good parametric model is to keep things simple and go back to fix earlier features to correct a mistake rather than add more.
