UNABLE TO WRITE TO MANDREL FILE
This indicates that there has been an error opening the mandrel file on disk or writing to it. This could occur for a number of reasons.
- The file name the user has supplied could be an invalid DOS name, for example the characters . " [ ] : < > + = are illegal. Refer to your system manuals for valid names. After clearing the error message the 'SAVE' option can be re-tried using a new name.
- The disk drive could have no space left on it. If this is the case you will need to exit from Cadfil without saving the file, and to create some more space or run Cadfil on a different disk.
- If you are running from a disk root (\) directory there is a limit to the number of files/directory entries that exist. This limit may have been reached, in which case you will need to exit from the program without saving your data and either change directory, disk or delete some unnecessary files.
- An unexpected error. If an error occurs that cannot be explained by any of the above, then contact CCL with the details.
UNABLE TO OPEN MANDREL FILE
This error message occurs when the software is unable to find a mandrel file to read, that is, the file specified by the user does not exist in the working directory. After clearing the message the user can select the option to read the file again and supply a new name.
ERROR READING MANDREL FILE
This error occurs when reading the mandrel file, if the data in the mandrel file is corrupt or not in the correct format. The format of the mandrel file can be found in the appropriate appendix.
X POSITION REPEATED - IGNORED
The message occurs when the user attempts to create a new mandrel point whose X co-ordinate already has a radius specified. The new X,R position is ignored, that is, it is not added to the mandrel data. To allow two different radii at the same mandrel position creates a step in the mandrel which it would not be possible to wind over. If for some reason the user wishes to create a step in the mandrel, for example on a boss at the mandrel end then X values that are very close to each other can be used.
STEP IN MANDREL, POINT REMOVED
When the mandrel data is saved or read some checks are performed on this data. One of these checks is for a step in the mandrel, that is two X positions that are equal and of differing radius. If this occurs the first X,R position is deleted prior to writing the data to the disk.
ZERO RADIUS IN MANDREL, POINT REMOVED
When the mandrel data is saved some checks are performed on this data. One of these checks is for a zero (or negative) mandrel radius that is not at the end of the mandrel. A zero radius is allowable at the ends of the mandrel but is not permitted at other locations. If this situation occurs the offending X,R position is removed as the data is being read or saved.
UNABLE TO OPEN THICKNESS FILE
This error will usually be caused by the thickness file specified by the user not existing in the current directory. If this error is caused for some other reason then contact CCL with the details. If this error occurs whilst updating the mandrel in the payout path section of the software then this must be due to a system error, the user should supply details of this to CCL.
ERROR READING THICKNESS FILE
This error is caused due to an error in the format of the thickness file. The format and structure of this file can be found in the appropriate appendix. If this error occurs whilst updating the mandrel in the payout path section of the software then this must be due to a system error and the user should supply details of this to CCL.
