Go to Solution.
1) Go to Edit sheet-->custom size-->change the values of height & lenght.
2) Just Drag & drop the required command/option and Place it on Top border Bar or where ever you want.
Have you set your sheet sizes i Customer Defaults?
Have you set a path to your Symbol library?
Sure.. I'll do that .
You have to type all the Landscape and Portrait sizes into the Customer Defaults so they appear on your Edit Sheet dropdown.
