Angled Sweeps

[sjsl]

How come you can use the Model Fascia tool and it will follow the angle of the roof, but, if you try to use the wall sweep tool you can only go v or h. but no angles.

Doens't it stand that they could turn this little switch on that says, "Oh he wants to put this on an angle know problem."

Revit is chock full of these little PITA's! It's frustating while your boss is standing there saying oh could you put some trim up under the eave like we did on the v and h areas?

Auh, No. Well that seems really stupid. How much did we pay for this software?

With an inplace sweep you can control the angle of the profile. with a wall hosted it is perpendicular to the wall so if you want and angle you just open the profile and rotate it there or add a angle parameter to the profile.

uhh...you can do it. You just need to know how to use the tools. Use an In place family. Maybe sometime in the future we will get an angle parameter for Wall Sweeps.

With a little over 4 months experience using Revit serioulsy, this is one of, if not the most, perplexing issue I encounter. I even asked this question this week in a 3 day class I took and recevied NO answer.

It just seems so basic, given Revit can sweep angled roof profiles. I even thought of making (if I had the experience, which I don't) a family sweep with pitch, size, etc. parameters.

With the pitch that Revit will reduce design/drafting time and increase output, why should we have to 'stop and create' something so common as rake wall sweeps?

Can you post and example of what a rake wall sweep is? If I understand, I think it is a sloped board at the bottom of the siding above the stone veneer. You just need to make a profile that shape and angle. A wall in revit is always vertical where a roof can have any angle and therefore require an angle parameter. Granted if something saves you time its worth asking for. But becareful, its kind of nice to be able to just edit the profile family and reload and all your sweeps get fixed. Where if I could modify the angle per sweep, I'd have more clean up to do.

If your rake sweep is following the angle of your roof can you do this using the soffit tools?

My boss was hoping to just point and click. I will setup an inplace sweep for him tomorrow so I can just point and click for him. Shame...

Hey Scott,

One example I might offer is a decorative foam cornice that is wall based, and abuts the bottom
of a roof/eave soffit. It works great on hip hoofs, until you have to follow a gable up an angle.

Edit: hey Dimitri, I think we just kinda alluded to the same condition :)

Thats when you use an in place family sweep, Cornice profile, and pick the top edge of the walls even along the gable as the sweep path.

could you put some trim up under the eave like we did on the v and h areas?


If you are following the roof line why not just use the facia sweep tool and adjust the vertical and horizontal offset parameters to place the sweep under the soffit up against the wall?

[Scott D Davis]

That's an even better idea! a "Fascia" doesn't have to actually fall on the fascia board!

[rookwood]

Mike is correct in that you can attach your sweep to the bottom of the roof and offset it. However, the problem arises when you terminate the sweep at the wall corner.

I don't have much experience with the Family Editor, but it would seem logical that you could create a custom 'rake' assembly (wall hosted) with the roof pitch and trim size adjustable. Or can't this be done?

I do agree that you need the flexibility of being able to create in place families, but these are items I use on every gable end and it would be nice to have some degree of 'automation'. It kind of seems defeatist to the concept of Revit to have to create 'standard issue' design on the fly for each project.

Rookwood, you are dead on to look for a family solution. Anytime you have something that you will repeat many times, is worth the effort to build it as a family with all the parameters you may need. Maybe a generic wall based family would do the trick? Can you post an image of what your after?

[Rhythmick]

I'm assuming dragging the end grip back to the corner will not work under your situation!

[rookwood]

The attached files illustrate a detail(s) I use on most all projects which causes me to curse endlessly.

How much of the gutter assemby and frieze/rake assembly can be 'automated' by use of families?

The assembly colored red is where I do most of my ad lib and usually end up using filled regions in elevation views. If you look at this detail in the attached rendering, you'll see I don't have them shown as they should be. It seems to me that a family could be created with parameters for the rake angle (roof pitch) and size of the rake and frieze boards.

Ofcourse, as I was sitting in the pool this weekend and I remembered what a rake board is, and yes I use a family for these, it is a simple extrusion in exactly the shape you show, I can adjust the thickness, slope and board height. It leaves a little joint on the perpendicular elevation(which may be there in real life) but if you don't want it you can hit it with the linework tool). The nice part is you can copy/mirror etc. The bad part is its not parametric with the roof, you have to edit the family to change the slope. But I don't think a fascia would work because you couldn't get the corner detail your after. Recognize this file was created many versions ago, I haven't needed it in a few years, but it should get the idea across.
