Shoulder Design Journal Files

Journal files can be used to capture the MX commands used by the wizards so they can be rerun at a later time. In most cases, the journal file will need to be edited to make it more useful. This documentation focuses specifically on the shoulder design wizard, but the methods described can be applied to other applications.

Creating the Journal File

Create the journal file by selecting Open Journal File... from MX's File menu. You will be prompted for the name of the file. Choose a name that could be understood by someone else working on the project. After selecting the file name, you will be prompted for the recording method to use. There are 3 options: Record and Rationalize, Record without Rationalization, and Record Everything. Opinions vary about which method is preferred. The first is the default option and it gives the least number of lines necessary to repeat the process. Once selected, the journal file will record all MX commands issued until the file is closed or the session ended.

Run the shoulder design wizard. For tips on this process see Shoulder Design in MX.

After completing the design close the journal file by clicking the stop button button.

Editing the Journal File

The newly created journal file may run just fine. However, with a few modifications it will be much more useful.

The shoulder wizard will create ER (shoulder crown) and ES (shoulder edge) strings. It is a good idea to add EDIT/004 options to the beginning of the file to delete the strings that are about to be created. This eliminates the possibility of outdated information existing in the model when the file is rerun.

ER strings are created with gaps in areas where the strings are not needed. By default, these gaps are defined by point number in the journal file. If there have been any changes to the alignment since the last time the file was run, the point numbers will be out of sync with the input file. When the journal file is created, it is a good idea to go through it and replace the point numbers with coordinate information. For example, a section creating the gap in the ER string will look something like this:


Report on the ER string to find the points defining the start and end of the gap.

25 1085346.860 545469.776 1178.582
26 1085357.549 545471.096 1178.497
27 1085382.360 545474.159 1178.299
28 1085407.172 545477.223 1178.102
---- String Gap ----
29 1086656.287 548900.954 1120.825
30 1086654.462 548925.888 1120.164
31 1086652.636 548950.821 1119.456

Replace the point numbers with the appropriate coordinate values as shown below.

006,3=ER2I,5=1085407.172,6=545477.223,8=1086656.287 9=548900.954
