Recognize Profiles

The ImPlant - I.exe program stores the definition of the profiles as read by the program through the Profile macro file as described in a previous section.

For each DGN projected surface, the program compares the profile of the surface with the profiles stored. If it finds a match, the program then generates Framework and Section elements. The Section element provides the SPRE, POSS, POSE, BANG, DRNS and DRNE attributes (refer to Model Reference for definitions of these attributes). The attribute SPRE is set to the spec_name as given in the Profile file.

To match a profile of a surface with a predefined profile the program checks:

• That the number of points in each profile is the same

• That the total length of each profile is the same (within a tolerance)

• That the area of each profile is the same (within a tolerance)

• That the lengths of each span of each profile match (within a tolerance)

• That the angles between each span of each profile match.

  Note: Circular or curved steel sections are not considered for matching.

  Note: There may be circumstances in which a profile is matched even though the projected surface did not represent a steel section.

The STEELTOLERANCE command may be used to change the tolerance used in this matching process.
