grid help...

[Domdeezy]

Ok Just got this project of a 20 story tower to recreate in Revit. The problem am having is with the grids. Is there to segment the grid line with a straight line then a radius line then back to straight? See attached photo. Along grids A thru D. The other problem I can't get the grids 1 thru 12 to show up in elevations or sections. If I rotate the view perpendicular to the grid line am only able to stretch that grid above 20th floor. Is there any easy way to get all grid lines to show above 20th floor?
Thanks
Dom

Not sure about that 20th floor thing, but as for getting your radius grids, just draw the first one like normal and then do a radius array and you should get your desired affect.
