Repeatability
When a pipe is detailed which needs splitting over more than one sheet, ISODRAFT automatically generates split points. By default this data is not stored, so if the design is altered and the pipe detailed again, the split points may be in different places.
If the user uses the REPEATABILITY command, sheet split points are written back into the DESIGN database. This means that when the pipe is detailed again it will be split in the same places. The user can reposition the split points if needed. Repeatability allows the user to re-plot single sheets when they have made changes to the design which only affect those sheets. Repeatability is not available for system isometrics or equipment trims. The split points are not set by ISODRAFT; an inter-DB connection macro is generated to set them in MODEL.
Restrictions on Repeatability
•
Split ATTAs will not be automatically created if some already exist in the pipe.
•
Re-ordering branches will destroy the integrity of the repeatability data.
For a major redesign, the user should remove repeatability data from the database and regenerate it.
If repeatability has been set, individual spools and sheets can be re-plotted using the DETAIL command. Individual sheets and spools can be entered into the Add and Remove lists using the ADD and REMOVE commands.
