Hi @Kassimsaad01280 ,
Creating Model Documentation Drawing Views is not available in AutoCAD for Mac, therefore VIEWBASE command is not available on Mac.
But you can try an old method of creating 2D views from 3D objects created in Model space:
it is combination of SOLVIEW, SOLDRAW and SOLPROF commands.
You can create orthographic views, layers, and layout viewports automatically for 3D solids with SOLVIEW command, than create 2D profile images of 3D solids for display in a layout viewport with SOLPROF command and generate profiles and sections in layout viewports with SOLDRAW command.
You can also look here:
