** Abstract: **
An amplitude analysis of the D+,D_s^+ -> pi- pi+ pi + Dalitz Plots
is presented using data collected by the Feremilab high-energy photoproduction
experiment E687. The data are fitted to a model consisting of a sum of
relativistic Breit-Wigner amplitudes for the intermediate two-body
resonance decay modes plus a flat non-nonresonant contribution.
From the fit we derive decay fractions and relative phases we aslo
present measurements of D^+,D_s+ --> 3 pi /K- K+ pi+ branching ratios.
