Profile or pillar in bulb view (BD, FL, FH lines)

The BD, FL, and FH lines define the position and presentation of the profile contour lines in bulb view.

The BD/FL/FH lines section can be omitted from the type files of standard profile types. If omitted, the standard profile will be presented in the standard way. User defined profiles always need the BD/FL/FH lines section.

  • The BD lines define the contour lines of the body or bodies of a profile. There are either two or four BD lines in a type file (two lines for each body), or no BD lines at all.
    • Profiles similar to unequal profiles need two BD lines.
    • Profiles similar to HEB profiles need four BD lines.
    • Profiles similar to an axis do not need any BD lines.
  • The FL lines define the position of the contour lines of the flange or flanges. There are either two or four FL lines in type file (two lines for each flange).
  • The FH line defines the flange height related to the profile body.

Values in BD lines

  • MS: profile or pillar seen from below. Profile MS lines are always presented with dashed lines.
  • TS: Profile or pillar seen from top.
  • S: presentation with a solid line.
  • D: presentation with a dashed line

Example: There are two bodies in the profile. The first and second BD lines define the molded and thickness side of one body. The third and the fourth BD lines define the molded and thickness side of the other body.

BD 0 MS S TS S

BD V9 MS D TS D

BD V1 MS S TS S

BD V1-V9 MS D TS D

Values in FL lines

The first FL line is at the flange base, and the second FL line at the flange size. In case of two flanges, the third and fourth FL lines are at the at the second flange base and size.

Syntax: FL <position related to moulded side> SH {S|D}

  • S: Show flange line.
  • D: Do not show flange line.

Examples:

FL 0 SH D

FL W1 SH S

Values in FH line

The value in the FH line is needed for the correct length and position of the flange lines according to the body lines. For example, an unequal angle bar has only one flange at position H1, and an INP profile has two flanges, one at height 0 and one at height H1.

FH must be followed by one or two values, depending on the number of flanges shown.

Example:

FH H1
