I usually use Steel Pro for W section, and other rolled sections. I just tried it for a bar joist - I set the depth to 10" and the bearing to 2 1/2". The resulting output has the bearing at 2 17/32" and the total depth at 11 1/4" - which is very confusing.

Hi Neil, I input the same values and my overall height was 11-1/4" also, but my bearing was correct at 2-1/2". I tried Rel. Cart. and Dir. Dist. with the same results. I found that 10" shows up as the distance between the one edge of the angle to the the start of the opposite. I don't work that type of joist system much so I couldn't tell you if it actually worked correctly in the past or not. Maybe something in the macro used to reference something like mirroring the profile of the angle for the top and bottom chords and something in Datacad has changed causing the draw point to be at the wrong side of the profile or something? Who knows. I think Datacad has the rights to the macro now so maybe Dave can peek at it? I tested a 12" joist with the same result. Would be nice if we could pick the section to be used for the top and bottom chords.

Thanks Josh, for checking.

I compared this to the bar joist symbols we have available, and those have the total depth of the joist correct. As I understand bar joists, they have standard depths and weights, so the macro could be set up just like it is for all the other steel items it draws. I needed to draw the 10K1 joist, which is the smallest standard size, apparently.

Here's all the standard sizes:


10″ Deep Steel Joist: 10K1 (NOTE: 8K1 joists no longer listed by SJI)

12″ Deep Steel Joist: 12K1, 12K3, 12K5

14″ Deep Steel Joist: 14K1, 14K3, 14K4, 14K6

16″ Deep Steel Joist: 16K2, 16K3, 16K4, 16K5, 16K6, 16K7, 16K9
