Solved: NX error - Unable to import cgm due to error: File not open , while importing CGM drawing in NX 10

NX error while importing CGM drawing file

In NX 10 or previous versions, if you receive an error while importing an CGM file, then try the following solutions.

Solution 1: 

Ensure that you are in drafting mode and try importing the CGM file. Currently if you are in modeling application, then switch to drafting application and create an empty sheet and try importing the CGM file into NX.
Your CGM file will be imported as a new sheet as per the default settings.

Solution 2:

If the above solution does not works, then there are possibilities that you don't have write access to specific folder where the CGM file creates a temporary translation file while importing into NX. To resolve this issue, right click the NX icon in the desktop and go to properties.
Change the Start In folder location from default path to some other path which you have right access. For example if you have access to D:/temp , then replace the default path with this new path.
Now restart NX and try importing the CGM file into NX drafting application.
