numbers must be the same as their ‘Part numbers’
Insert segment points e.g. from 0 to 140 Step 4

Assign cross sections to all the points
Starting at the top of the list: Assign beam
element numbers and material numbers to the
parts automatically
N.B. Elements numbers can be directly defined
by selecting the parts radio button and then the
edit icon.
