Are the items crafted by blacksmith affected by magic find rate?

Based on the information of Diablo 3 Wiki, that property only affects "the odds for found items (from monsters or objects) to be "higher quality"", so nothing to do with Blacksmith or crafting.

Magic find never affects the selection of affixes for an item, only the base quality of the item. Since this is pre-determined during crafting, magic find has no affect.

Yes, an old post, but for anybody looking for these kinds of answers ...

Most of the info that people replied with above is wrong. No, MF doesn't affect crafting, only gear that is dropped from killing monsters. Yes, MF affects both the quality of the item and number of affixes on the item.
