Missings hidden lines in standard content shapes

[aruthenbeck]

I am working in AutoCad Mechanical 2013 with standard content (structural shapes, etc).  Just recently when using this standard content, the hidden lines have gone missing.  I have all layers turned on and the hidden lines still show up in the content editor (although you can't make changes to standard content).  Any idea on how I can get them back, I use the standard content frequently at work?

I attached a picture of a structural tube which is not showing the hidden lines.

Hi,

I tried to insert a few steel shapes and I could find the hidden lines.

For close look, can you share a sample drawing or send it to zhiyuan.su@autodesk.com?

In case it happened to other users. 

You can check with factory default settings. You can try to reset settings to default by start menu->Autodesk->AutoCAD Mechanical 2013 – English->Reset Settings to default. Note that do save your custom setting when it prompted you so you can import it back after the checking.

Before activating the hidden lines AMbrowser but the contents are not visible hidden line thereafter activate the AMbrowser.
Even off the back AMbrowser invisible line of content is hidden.
This phenomenon seems to occur contents hidden lines are locked simultaneously with the execution of amborswer.
I hope to find the exact solution given write.
PS. When you run the Reset if the AMbrowser The same phenomenon occurs.
