How do you, or can you, have the joist seat bearing stay horizontal on a K series joist when the joist is sloped?

How do you have revit cut a section at a sloped joist, bearing on a beam, joist girder etc. and have it show a little more accurately in the section.

"How do you have revit cut a section at a sloped joist, bearing on a beam, joist girder etc. and have it show a little more accurately in the section."- Create a ref. plane then use the "Cut Geometry" tool to cut the beamto that ref. plane

That's not what I meant, What I want to know is when you have a K series steel joist or joist girder that is at a roof and the joist is sloping, at the bearing seats the seat is manufactured horizontal to the bearing point while the joist is sloped. Right now Revit shows the seat sloping so when you cut the section it's not shown correctly. Thanks in advance.

You would need to modify the joist family...I haven't done this as it would take a bit of time and if you are not familiar with family creation/modifcation it could take even longer. A quick and dirty way I have shown this is in the detail only. I will draw a masking region to hide the parts of the sloping joist as needed so I can add detail lines for the seat.

Thanks for the reply. I was afraid that it was going to have to be a work around. Sometines it seems like Revit Structure is just lacking features.

Yeah - I hear you. Since the joist family is one that comes right out of Revit, I would like to see it have features like sloping joist seats, double pitched top chord, etc. I haven't seen joist manufacturers offer any Revit content, have you?

No, I haven't found any. The 2D drafting in Revit leaves a lot to be desired.

I used to find myself in a constant battle of deciding what to model exactly as it will be constructed; what to model so it becomes easier to detail; and what not to model. In my current situation, our models are never used or provided to the owner for use with as-builts or anything towards that nature - so I am pretty free to do whatever is the easiest to get the final production drawings out in the least amount of time. This has helped with the on-going battle I mention above. As you work thru some of these things it will become easier and the 2d drafting features will become more second nature. They are powerful.

Its actually not that difficult to modify the joist family to show the sloped seat. All you have to do is add a blend showing the sloped seats, a couple void extrusions to clean it up, and some formulas to constrain the geometry and visibility.

RevitAggie, Obviously you know a lot more about editting families than the rest of us. Could you please spell out your process in idiot proof terms so that we know what your talking about. Thanks, Dumb Old Guy

Do you happen to have the RFA file for this? I am trying to do it manually but keep striking out.
