expedition change clearnance for several nets

I have default clearance set as 10, min is 10, I want to setup a new clearance of 7. But it does not let me define the clearance for nets, only the trace width. I cannot change the min also, it is readonly.
What is the procedure to reduce the clearance for some nets? The CES tool is really confusing.
thank you

Re: expedition change clearnance for several nets

There are several possibilities for this situation.

• When you launch Constraint Manager on a read-only .prj file, it opens in read-only mode. You should check to ensure that you have write access permissions for the .prj file.
• Ensure that your WDIR variable is configured properly. There must be a writable directory in the WDIR path.
• CES database is locked / read-only when you open CES from DxDesigner. The lock is held by the file "<projectpath>\CES\lock\<projectname>.db". After checking that no one is in the database, delete the file.
