<P>The geometry can be physically measured using traditional hand </P>
<P>tools, non-contact inspection equipment, a touch-probe coordinate </P>
<P>measuring machine (CMM) or a portable CMM. The geometry can also </P>
<P>be 揷aptured?by mapping the surface with a laser, white light </P>
<P>scanner, full contact CMM scanner, or a process called Capturing </P>
<P>Geometry Internally (CGI).</P>
<P>It is important that the correct method be used to capture </P>
<P>geometry for any reverse engineering project. The method is </P>
<P>dependent on the part shape, required accuracy, project goals, </P>
<P>and how the final results will be used.<BR>大家帮帮忙,急需的呀。谢谢拉</P>
