Invalid Layer Category Name in CMM migrated Drawing
Invalid Layer Category Name in CMM migrated Drawing Description of Problem:
There are drawing layer names that can exist in I-deas Master Drafting that are not valid names in NX. The user believes that CMM should correct these errors during migration.
How to reproduce the Problem:
A package file of a drawing is being supplied. This issue can be reproduced with CMM Solo. Do the following:
Migrate the supplied package file.
Open the migrated drawing in NX.
Select "Format --> Layer Category"
Select the first named layer category in the list ( AICHACH X 1234)
Select "Create/Edit". An error message will appear that states:
Invalid characters in category name.
Please enter a new name.
The reason the name is invalid is that there is a leading space in the name. The user believes that CMM should be eliminating any invalid characters during the migration.
Workaround:
Rename the layer in I-deas Master Drafting before migrating the drawing or rename the layer category in NX after the migration.
Platform(s) and version(s) tested on:
CMM Solo 6.0.2
Data or platform specific?:
Data specific
File type and Data Being Supplied:
Windows zip file containing an I-deas package file.
Other Information:
None. Siemens PLM believes that the problem you reported where migration issues resulted from certain drawing layer names that are valid in NX I-deas and are not valid in NX will be resolved by code changes made to NX 6.0.5 and CMM 7.5.
