Hello,
The semisphere type of cap plate required for the pipe bollards is not avaliable as an Advance Steel as a predefined object / macro. In order to obtain the required object in Advance Steel, you need to create it as an Autocad ACIS object, save it in a file which then is placed in your Symbols folder ( C:\ProgramData\Graitec\AdvanceSteel\2010\Shared\Support\Symbols ) and then add it in the model using the function : Advance Steel Special Part ( C:\ProgramData\Graitec\AdvanceSteel\2010\Shared\Support\Symbols )
But, this type of element can't be detailed in a single part / main part detail drawing. You can only add them to Overview type of drawing.
