    ,Forme##other##,Ix##other##,Sx##other##,A##area##i nches,M##other##,Ht##length##inches,b##length##inc hes,t##length##inches
    HSS762x610x12.7,Rect.,291778,7669,51.9,263,30.0,24 .0,0.500


    I want to change the dimensions of HSS beam-hss-80x40.png
    Please help me i'm french and i don't have the anglosaxon logic of geometrie.

    Thank!!!

    ... and I'm American, so I hope I can understand what it is that you are asking in your post.

    It looks like you want a HSS shape, a new shape, that is 80mm deep x 40mm wide with a wall thickness that is 3mm.

    Do you not want to enter a shape into your project and do an "Edit Type"? Then you load any HSS shape (from the HSS family**,) place it, and then you can "Edit Type" and "Duplicate..." thus creating any new shapes to meet your requirements.

    But it looks like you want to add it to your .txt library file? In America, that .txt library file has parameters and values that have been coordinated with our AISC steel manual. If you are going to use this new HSS beam for analysis and quantity takes offs, you may need to calculate your analytical values, weight, modulus of elasticity, etc. But, the .txt file gives you the information that you'll need.

    According to what you entered in your Original Post, you'll need the following information, placed in one line, separated by commas (,).
    Forme##other## <-- this will represent the name for the type. In your case, it will probably be HSS80x40x3
    Ix##other## <-- this will represent the weight (maybe?) for the member
    Sx##other## <-- this will represent ??? (I'm not seeing this in my Imperial family .txt file)
    A##area##inches <-- this will represent the area of the steel in a section of the shape
    M##other## <-- again, I'm not sure because I don't see this in my Imperial family .txt file
    Ht##length##inches <-- this will represent height of your member (though this looks like it's in inches instead of millimeters)
    b##length##inches <-- this will represent width of your member (though this looks like it's in inches instead of millimeters)
    t##length##inches <-- this will represent wall thickness of your member (though this looks like it's in inches instead of millimeters)

    For example (and I'm taking this from an Imperial family):
    ,Shape##other##,W##other##,A##area##inches,Ht##len gth##inches,b##length##inches,t##length##inches
    HSS20X12X5/8,Rect.,127.000,35.000,20.000,12.000,0.581

    Shape##other## <-- type name = HSS20X12X5/8
    W##other## <-- weight = 127.000
    A##area##inches <-- area = 35.000 (in inches)
    Ht##length##inches <-- height = 20.000 (in inches)
    b##length##inches <-- width = 12.000 (in inches)
    t##length##inches <-- wall = 0.581 (in inches)

    **Going back to look at my metric family .txt file, I see that the values are definitely in millimeters. You should probably start with a metric family.
