----------------------------------------------------
                USING STEEL.MA
----------------------------------------------------
1. Installing STEEL.MA
   The following files can all be placed in the 
   Bentley/MicroStation/mdlapps directory:
    steel.ma
    steel.txt
    steel99.stbl
    cisc.stf
    corusCUSTOM.stf
    German.stf
    japan.stf
    korean.stf
    maisc.stf
    pacific.stf
    Polish.stf
    Russion.stf
    uk.stf
    usAISC21.stf
    usLRFDv3.stf

   The steel section data files (.stbl and .stf files) can be put in
   different directories if desired (see below).

2. Starting STEEL.MA

   In the MicroSation 'Keyin' dialog box type 'mdl load steel'.
   After the application is loaded, a 'Steel' tool box will be
   displayed. The tool box contains two icon: 'Place Steel Section',
   and 'Steel Section Parameters'.
   Clicking on place steel icon will start placing a steel section.
   The steel section is chosen in the Tool Settings dialog. Additional
   placement parameters are in the Steel Section Parameters dialog,
   accessible using the Steel Section Parameters Icon.


3. Section data tables

   When the application starts up, it reads one or more steel section 
   data tables from ASCII file(s). These files contain the section dimensions. 
   Version 8 of the steel application supports two different steel table formats.
   One format is that of the "steel97" application that has previously been 
   available, and the other is the steel table format from the Structural for 
   Triforma application. The latter format have been updated more recently and
   are believed to be more reliable, however there is no warranty, express or implied
   regarding the accuracy of the steel table information in either format.

   A number of steel section files have been included - steel99.stbl, which was compiled
   for the steel99 application available on the ProCADD web site (www.procaddj.com),
   modified to the steel97 format; and 12 steel files in the Structural for Triforma 
   format (cisc.stf, corusCUSTOM.stf, German.stf, japan.stf, korean.stf, maisc.stf,
   pacific.stf, Polish.stf, Russion.stf, uk.stf, usAISC21.stf, usLRFDv3.stf). We 
   recommend that you select the steel tables that are applicable to your work
   and delete the rest. Alternatively, they can be moved to different directories
   and the STEEL_TBL configuration variable set up to find the appropriate tables
   for a particular project (see below).

   The format of steel97 application ASCII data format contains the section name,
   section type, and dimensions.

   ------------------------------------------------------------------

      The section types are:
      
      Type ID     Shape type
      -----------------------------------------
      1            W-Shape
      2            S-Shape
      3            HP-Shape
      4            M-Shape
      5            C-Std. Channels
      6            MC-Misc. Channels
      7            L-Angles
      8            WT-Tees
      9            MT-Tees
      10           ST-Tees
      11           Struct. Tubing
      12           Std. Pipe
      13           X-Strong Pipe
      14           XX-Strong Pipe

    Files in this format must have the extension ".stbl".

    The Triforma format differs in some particulars. See the beginning of the
        file usLRFDv3.stf for documentation. These files must have the extension ".stf".
	Note that the steel application cannot process steel sections with types 
	6,7,8,13,14,15,16, and 17 in .stf files - their definitions are simply ignored.

    The Triforma format follows the new AISC guidelines and does not include
	fillets for many of the shapes, since these vary widely during manufacturing.
	The program supports nonzero radius values, but in many cases the radius is
	set to zero. More of the .stf format steel section files will be available soon.

    The application finds the steel tables using the following algorithm.
    a. If there is a configuration variable "STEEL_TBL", the application looks 
        in that directory for all files with extensions ".stbl" and ".stf" and attempts
	to read them.

    b. If there is no configuration variable "STEEL_TBL", the application looks in
	the directory that is pointed to by the MS_DATA configuration variable and attempts
	to read all files with extensions ".stbl" and ".stf".

    c. Looks in the directory pointed to by the "TFDIR_DATA" directory, if there is one,
        for files with ".stf" extension.

    d. The application always looks for all files with extension ".stbl" and ".stf" in 
	the directory that the application is loaded from.

4. Placing sections

   - Click on the "Place Steel Section" icon.
   - Select the appropriate steel section table from the top option button.
   - Select the appropriate steel section type from the second option button.
   - Select the desired section by name in the combo box.
   - Choose whether to fill or hatch the steel section, or neither.
   - Indicate whether you want to create a cell from the steel section.
   - The cell name will be the section name if this is turned on.
   - Choose colors, etc., by using the Steel Section Parameters dialog,
     if desired.
   - The hatch spacing is equal to the current text height times the spacing factor.
   - The justification point is stored per section type. To change it, edit the value
     in the Justification column of the table in the parameter dialog. Double click
	 slowly in the desired cell to get the combo box to come up.
