Hello,
What do You want to do? Edit FALSE size? Add additional operation (chamfer, blend etc.)?
If You want edit size You must edit Spreadsheet. Go to: C:\Siemens\NX90\MOLDWIZARD\standard\metric\dme\data, find file .xls and edit it.
If You want edit solid body go to: C:\Siemens\NX90\MOLDWIZARD\standard\metric\dme\model and just edit prt. File. FALSE is on 99 Layer.
Important!!!
First of all You must create backup folder DME
regards
Marcin
