1. A fixed abrasive article comprising: a body having abrasive particles contained within a bond material, the abrasive particles including a plurality of shaped abrasive particles or elongated abrasive particles having an aspect ratio of length:width of at least 1.1:1, each of the shaped abrasive particles or elongated abrasive particles having a predetermined rotational orientation angle relative to a side surface of the body,wherein the body comprises a first group of abrasive particles arranged in a controlled distribution relative to each other and positioned within a first radial plane within the body, each of the abrasive particles of the first group having a predetermined rotational orientation angle within the first radial plane relative to the side surface of the body,wherein the body comprises a second group of abrasive particles arranged in a controlled distribution relative to each other and positioned within a second radial plane within the body, each of the abrasive particles of the second group having predetermined rotational orientation angle within the second radial plane relative to the side surface of the body, andwherein the controlled distribution of at least one of the first group of abrasive particles and the second group of abrasive particles comprises a phyllotactic pattern. 2. The fixed abrasive article of claim 1, wherein each of the shaped abrasive particles or elongated abrasive particles have a predetermined position and a predetermined three-axis orientation. 3. The fixed abrasive article of claim 1, wherein each of the shaped abrasive particles comprises a cutting tip or cutting edge having a predetermined rotational orientation relative to the side surface. 4. The fixed abrasive article of claim 1, wherein an abrasive particle of the first group of abrasive particles is radially and axially staggered relative to an abrasive particle of the second group of abrasive particles. 5. The fixed abrasive article of claim 1, wherein the first radial plane and second radial plane are axially spaced apart from each other within the body. 6. The fixed abrasive article of claim 1, wherein the first group of abrasive particles have a first predetermined rotational orientation and the second group of abrasive particles have a second predetermined rotational orientation different than the first predetermined rotational orientation. 7. The fixed abrasive article of claim 1, wherein the abrasive particles of the first group and the second group have at least one abrasive characteristic that is different. 8. The fixed abrasive article of claim 1, wherein the body comprises a plurality of groups of abrasive particles associated with a plurality of different radial planes within the body, and wherein each group of the plurality of groups of abrasive particles includes a plurality of radial sets of abrasive particles, wherein each of the radial sets are spaced at a different radial distance from a center of the body relative to each other. 9. The fixed abrasive article of claim 1, wherein the body comprises a first axial collection of abrasive particles within a first axial plane within the body, each of the abrasive particles of the first axial collection having a predetermined rotational orientation relative to the side surface of the body, and wherein the body further comprises a second axial collection of abrasive particles within a second axial plane within the body that is different than the first axial plane, each of the abrasive particles of the second axial collection having a predetermined rotational orientation within the second axial plane relative to the side surface of the body. 10. The fixed abrasive article of claim 9, wherein the abrasive particles of the first axial collection of abrasive particles are arranged in a controlled distribution relative to each other and wherein the abrasive particles of the second axial collection of abrasive particles are arranged in a controlled distribution relative to each other. 11. The fixed abrasive article of claim 9, wherein the abrasive particles of the first axial collection have at least one abrasive characteristic different than the abrasive particles of the second axial collection. 12. The fixed abrasive article of claim 1, wherein the predetermined rotational orientation angle defines an angle between a radial axis and a particle axis, wherein the predetermined rotational orientation angle is between about 0.1 degrees and about 90 degrees. 13. The fixed abrasive article of claim 1, wherein the shaped abrasive particles or elongated abrasive particles have a predetermined lateral axis rotational orientation angle between about 0.1 degrees and about 90 degrees. 14. The fixed abrasive article of claim 1, wherein each of the shaped abrasive particles have a body that is essentially free of a binder, or wherein the body is essentially free of an organic material, or wherein the body is essentially free of rare earth elements, or wherein the body is essentially free of iron, or wherein the body is formed from a seeded sol gel.
