UNABLE TO READ FIBRE DATA

This error is described in the section on fibre path generation errors.

UNABLE TO OPEN PAYOUT FILE

This error can be generated in trying to read the payout path file for viewing purposes. The usual reason for this will be that the file does not exist in the current directory. If a new payout file is being saved the error will probably be due to an invalid name being supplied and the user can enter a new name. Other possible sources of this error are listed under 'UNABLE TO WRITE TO MANDREL FILE' heading in section 0 - mandrel generation errors section.

ERROR READING PAYOUT FILE

This message is displayed if the payout path file being read is corrupted in some way. The format of the payout path file can be found in the appropriate appendix.

UNABLE TO READ OLD PAYOUT FILE

This error is generated if a payout file that was created by a Version of CADFIL older than version 3.00 is attempted to be read for viewing. After version 3.00 (when the payout path viewing options were added) some additional data was included in the payout path file header information. This information is the payout path clearance, the name of the mandrel file and the number of elements the mandrel, that were used in the creating of the payout file.

UNABLE TO OPEN MANDREL FILE

ERROR READING MANDREL FILE

The payout path file and fibre path file both contain the name of the mandrel file used in their creation. If a payout path file or fibre path file is being read the mandrel file also needs to be read. The nature of the errors is the same as those described in the mandrel generation section. The likely causes are that the mandrel file has been deleted or that the payout/fibre file has been copied to a new directory but the mandrel file has not. It error could be caused by a user editing the payout/fibre file and modifying the name of the mandrel file that is contained in it.

PAYOUT PATH DATA NOT WRITTEN

This message can be produced when the user is trying to create a payout path file when the file already exists and the choice not to overwrite this existing file has been made. After clearing the message the user is requested for a new payout path file name to use.

ERROR WRITING TO PAYOUT FILE

This error indicates that the payout file has been successfully opened but that there has been an error writing data to it. This is most likely to be due to the disk being full. If this is not the source of error then there has been an unexpected error and the user should contact CCL with the details.

FIRST HOOP POINT IS TOO CLOSE TO START OF PATH

RE-CREATE FIBRE PATH STARTING AT HOOP

As explained elsewhere, Cadfil requires two hoop points in the fibre path to be able to create a repeatable cycle. Hoop points are created in two ways. The first method is when the fibre is started exactly at hoop, and the second method it were the fibre is developed until it turns either due to the mandrel geometry or due to the application of friction. In this latter case the hoop point is not exactly defined and Cadfil uses various mathematical techniques to establish the exact position of the hoop point to ensure accuracy in the fibre track when it is reflected. For these methods to work correctly there must be at least three fibre points to each side of the point where the fibre is seen to turn on the computer screen. This error message is caused because the fibre was started very close to hoop and then turns around within a couple of steps. Hence the hoop position cannot be fixed accurately. In this circumstance to avoid this error, the user would be better to start the fibre position exactly where required using the hoop facility for the start angle.

LAST HOOP POINT TOO CLOSE TO END OF PATH

GENERATE THREE FIBRE SEGMENTS PAST THE HOOP POINT

This error is for similar reasons to that described above except that the fibre path needs to be advanced three or so elements further. The simplest solution is to return to the fibre path generation section, retrieve that old fibre path and the to advance three or so steps and then to save it again. The payout path will then be able to be created in the normal manner.

MATERIAL FILE ERROR-INTERNAL DEFAULTS USED

This message is given if the file material.cnf is not found or there is an error reading it. a set of default properties are assumed. These will be displayed on the screen for the user to select or to enter new values in the usual manner. Information on how Cadfil tries to locate this file can be found in appendix a, section 4 and the format of this file can be found in appendix B.

ERROR READING THICKNESS FILE

UNABLE TO OPEN THICKNESS FILE

Refer to Mandrel generation errors.

ERROR WRITING THICKNESS FILE

This error will usually be generated when the disk is full. The user will need to exit from the program and create more disk space.
