I am trying to make an offset cross section and everything seems fine except the one enclose box around the section view of the same size as section is.
After defining the section feature section looks ok for a second and then a box appear around the section view.
Can anyone help me in this regard ??
the problem is probably related to your data.
Yes problem is related to particular assembly only. In the other assembly offset section feature is working correctly.
But how can I find the problem, is there any way to check ?
I do not know any "one step" method. You have to find the source of the problem by yourself. Try suppressing "one half" of the assembly and test ... and so on.
The offset type section does not include the capability of including quilts.
What you can do is find the part and blank it from the drawing view. Or hide the surface layer.
A picture may also help us understand the problem.
If you use surface models or have a surface model in your assembly, you have to include quilts in your x-section.
