Unable to Edit sketch in NX-6

[ashivu123]

I am working in NX6. I have opened part that has sketch and some extrude on it. When I when double click on the sketch it went went to the sketch mode skech was no constrained and no dims in it. I tried to delete some curves in the sketch but they are not deleting even I used Trim option that also not worked. Let me know how can I edit or delete curves in the sketch.

thanks

Hi,
Is it an old file?
If it is so, you need to search (via Command Finder) for Pre-V13 Sketch.

Hi Pacal, Yes it is an old file. After many iterations I came to know that only one curve is attached to that sketch externaly by basic curve. I deseleced Extrude and deleted that basic curve. Now I am able to modify the sketch
