-1.000000
enables you to set a maximum allowed deviation between the original and the resulting surfaces during the conversion of creo
parametric surfaces to spline surfaces. for example, for iges this conversion occurs only when the iges_out_all_srfs_asoption is set to 114. for catia and vda, this conversion always occurs.
setting the maximum deviation enables you to convert surfaces with a better approximation than by using the current accuracy
of the model.
specify a positive value in the current model units to set the deviation. if the value that you specify is outside the accepted
range, the system uses the default model accuracy.
