Floor Trusses have been included into Wood Framing Truss+
add-on for Revit!

The influence of structural and non-structural walls to Structural Framing's and Wall's connections in Revit is undoubtable and known to many who struggled with them. Why struggled, you may ask? Basically, if the wall is structural, end point of beam or truss automatically moves to the wall's centerline instead of the external face of wall's structural core.

To prove a point, let's draw a beam in Revit:

If the wall is non-structural, we’ll get this result:

But if the wall is Structural, beam’s end point automatically moves to the wall's centerline:

That is not what we want.
But how do we fix this?

In order to move the geometrical end of the beam to the external face of wall's structural core, one should put quite a lot of effort. You can do that in two ways:

1. Calculate and then edit Start/End Join Cutbacks;

2. Edit beam's end point parameter, use “disallow join” function, and then drag the beam'’ end to the external face of the wall's core layer.

We can reposition the geometrical end of the beam to the desired position either way. You can take a look at the pictures below to get a better understanding about the workflow in Revit.

Let's try the first workflow:

1. We have to calculate and then edit beam's Start/End Join Cutbacks:

And now the second workflow:

2. In order to move the geometrical end of the beam to the external face of wall's structural core, we have to use Disallow Join function:

Result:

Now, we can drag beam’s end point to the external face of wall's core and get the final result:

That looks great! But it also requires a lot of effort. It took quite a lot of time to edit this single beam…and what if there are a 100 or more of them? And…what about trusses? It seems that we don’t have a possibility to reposition their geometrical ends.

Connection between a non-structural wall and a truss seems to be good:

But when we edit the wall to be structural, geometrical end of the truss automatically moves to wall’s center line:

What’s next?

AGACAD’s Floor Trusses comes to help.
Take a look at the following pictures and learn the quick an easy workflow.

First, measure the distance from wall’s centerline to structural core’s external face:

And enter the measured distance value in the special constraints type parameter:


That’s it!

The geometrical end of the truss is repositioned to the external face of wall’s core with barely any effort.

It couldn’t be easier.

Go ahead, download trial of AGACAD’a Wood Framing Truss+ RT for Revit and try that yourself.
