Abstract:	We present the results from 3D modelling of 31 nearby (<110 Mpc) edge-on spiral galaxies by a single disk component to address the radial truncation of galactic disks. We confirm for this sample the existence of such cut-offs (Rco), and find a significantly lower mean value of the distance independent ratio Rco/h = 2.9+/-0.7 than the standard value of 4.5 often used in the literature. Our present data show no correlation of these parameters with Hubble type, whereas we report a correlation between Rco/h and the distance based scalelength h in linear units.
