<P class=MsoNormal style="MARGIN: 0in 0in 0pt"><FONT face="Times New Roman" color=#000000 size=3>I created a model and incorporated a lot of changes during refinement process. I suspect that all those changes are slowing down the calculation process. Is there any way to create a completely new model from scratch and import all information <SPAN style="mso-spacerun: yes"> </SPAN>from the existing model and get rid of the history with all changes I made.<SPAN style="mso-spacerun: yes"> </SPAN>If not, is possible to delete the history from the existing model and to preserve the very latest inputs. </FONT></P>
