A method of making a coated abrasive article includes: depositing precisely-shaped abrasive platelets into precisely-shaped cavities in a production tool; depositing diluent abrasive particles onto the production tool; contacting the precisely-shaped abrasive platelets and the diluent abrasive particles with a curable make layer precursor disposed on a major surface of a backing; separating the tool from the precisely-shaped abrasive platelets and the diluent abrasive particles; and at least partially curing the curable make layer precursor to provide an at least partially cured make layer precursor. Coated abrasive articles preparable by the method are also disclosed.
