Exporting a model as IGES (STEP) vs. liveTransfer

Generally models made from scan data that are intended to be edited in a CAD program are transferred into the receiving CAD program using IGES or STEP file format. Even after a successful import of

CAD system has own kernel and specific interface. So, sometimes, liveTransfer may not perfectly forward a redesigned data to CAD system because of the difference between Rapidform and CAD system.

Problem

After you transfer splines (2D and 3D) that are used for, say, a Lofted Surface, you may want to edit the control points of the splines to do design changes. This document explains how to edit splines in each CAD system.
