I have an assembly and a drg for that assembly. Both are opening fine until i change the springs in that assembly. Once when i replace the spring with an another spring and when i try to open the drg for this new assembly then solidworks shows error saying that the section line partially cuts the assembly and and all the components in the section view is shown as dangling items.
I tried to do the same thing with a similar assemblies. Some are opening fine and some are showing the errors like this.
Please refer the attachment which shows the error message when i try to open the revised drg for the revised assembly.
