Linear Members

Linear members are either straight or curved. Modifications to straight members are detailed as below

LINMEM <ID> <state> <point> <size> <material> <rotation> <start> <end>

for example:

LINMEM =1234/5678 C Y Y Y N Y Y

The ID field will contain the internal database reference number by which the model components are to be identified between model versions. The state field may contain one of three options, A for added, D for deleted or C for changed. The other fields contain either a Y or N indicating whether the attribute at that location has been changed or not.

For curved members the member type is CURMEM but the attributes inspected for comparison are the same. The individual internal points along the SPINE are not compared.
