Where I'm still stuck is when the beams AND column need to drop 2/ 1/2" when they support joists. I like to set my top of columns to the deck bearing elevation and then place my beams from top of column to top of column using a z offset of -2 1/2". That's perfect for a k-joist beam system and when I change the top of column elevation, the column and beam and joists all change correctly. The problem is when a joist falls on the column line and the seat overlaps the column. In this case, the top of column really needs to drop the same 2 1/2" but I can't do that without the beams dropping an additional 2 1/2" and taking all the joists with them. This seems like the top "node" of the column really should be at the deck bearing elevation but the graphical column would drop. The z-offset, and attachment type settings of the beams essentially works like this, you would think the column would too.Anonymoushttps://www.blogger.com/profile/01582325286341293454noreply@blogger.comtag:blogger.com,1999:blog-9240097.post-30313476962788157512013-11-01T13:40:18.864-07:002013-11-01T13:40:18.864-07:00Steve - I wish there was a macro for this also sin...Steve - I wish there was a macro for this also since you cannot select all beams and change the Start and End Attachment parameter in one fell swoop. The "Attachment" parameter only exists for beam ends that connect to a column. If a beam connects to a column at both ends the Start and End parameters exist, if a beam connects to only one column the parameter exists only for that end, if a beam frames between 2 beams the parameter doesn't exist at all. Since a typical framing plan consists of all of the above conditions when you select all beams the 2 parameters do not show in the instance properties. This reinforces your idea for a nice macro.Jon Brazierhttp://o-n.comnoreply@blogger.com
