Hi,<br>Now in my problem, i want to clip one dataset by an extruded surface( polydata
<br>representation) .I am trying to assign scalars to the dataset <br>in the way where the suface intersects th edataset will be assigned a value ,and <br>one side of the surface greater than the value ,other side less than the value .
<br>then i can clip with the assigned value .<br>But how to assign values right ? that is ,How can i decide where the surface intersects <br>the dataset ? any suggestions?<br>btw., my dataset is one bat's ear shape ,i clip it just for visual purpose ,so dont want
<br>to be very exact .<br><br>thanks in advance.
