With this option it is possible to read a file in the Parasolid format (untile version 25001 - ASCII or binary).
The most usual Parasolid file extension is .x_t for ASCII and .x_b for binary format.
The variable ImportTolerance (see Preferences ) controls the creation of new points when a Parasolid file is read. Points are therefore defined as unique if they lie further away than this tolerance distance from another already defined point. Curves are considered identical if they have the same points at their extremes and the "mean proportional distance" between them is smaller than the tolerance. Surfaces can also be collapsed.
