I have made a 2D parametric CMU Detail (CMU = Concrete/Cinder Masonry Unit/block), to be used in your detail plans ... it's very easy to use and can save you time detailing.
I have made it in two different versions (english and spanish), so if anyone wants it in another language just send me an email: naderbelal_at_hotmail_dot_com
I have already uploaded it to BIMcomponents.com, but I don't know why it's taking time to be shown in public.
