Isometric Drawing

If required, you can produce the branches (new or existing) and the connection information in Isodraft. Refer to Connection to Equipment Nozzle.

When generating an isometric drawing containing non-standard branch connections (which use the PIPCA element), a detailed plot-file for each non-standard-branch-connection (PIPCA) is generated and stored in the project iso directory. For example, SAMPLE project files are stored in the SAMISO directory.

You must have write access to a draft database to generate plotfile(s). When a drawing is generated as a plotfile, a session of Draft is automatically opened and closed. If you do not have write access to a draft database, a warning message displays.

The database ADMIN/PADD (plant, SAMPLE project) must be in the current MDB as the drawing templates and drawing representation rules are contained in these.

It is recommended that you do not have a session of Draft open when generating isometric drawings containing non-standard branch connections

In order for detailed plot files to appear on the isometric drawing, the Display Plots option and associated positioning parameters must be set in the Isodraft Detail Plots window.

The detailed plot file displays in the designated area and is identified by a DETAIL tag on the main isometric drawing:

The drawings (DRWG) generated in Draft are saved in the department (DEPT) /NSBC_DRAWINGS/DEPT, under the registry (REGI) /NSBC_DRAWINGS/REGI with naming convention PIPE1_DETAIL.S1 where PIPE1 is the name of the pipe and S1 increases with each PIPCA found under that pipe (PIPE1_DETAIL.S2 for the second PIPCA)

The plotfiles are saved with the naming convention PIPE1_DETAIL.S1.plt where PIPE1 is the name of the pipe and S1 increases with each PIPCA found under that pipe.

If a user wishes to modify the detailed plot, the generated drawing can be modified in Draft. The plotfile must be saved in the project ISO directory (alongside the automatically generated plotfile(s)), with '_MOD' added to the file name after '_DETAIL' (for example, PIPE1_DETAIL _MOD.S1.plt). When the isometric drawing is generated, the plotfile with the modified name (_MOD) is used instead of the automatically generated one.
