RAC 2009 - no sweep up roof hips and ridges

[ws]

Is it just me or in RAC 2009 can I no longer use the Host Sweep with Fascia or Gutter option to sweep profiles for ridge tiles along hips and ridges?

This used to be a very nice time-saving trick but doesn't work as far as I can see in 2009.

Not sure about fascia sweep, but I know for a fact that Revit has never allowed gutter sweeps on anything other than a perfectly flat roof eave edge, i.e. either the edge of a flat roof, or edges that are slope-defining and are flat themselves.

*edit* just checked, and I applied a roof fascia sweep to a gable roof edge just fine in 2009, exactly like I have always done. Gutters still can only go on flat, non-sloping edges.

Thanks, I could never remember until I tried it whether it was fascia or gutter sweeps that worked and so I guess it was always fascia sweeps.

It still works fine on the regular edges of roofs but until this release it also worked on hips and ridges which was very handy (see attached) - you just changed the profile to a ridge tile and it zipped around the roof...

Now in RAC 2009 I have to create a sweep and pick a path for the profile manually.

Maybe they are excising all the non-standard tricks ?

Oops, didn't notice the part about hips and ridges. Yeah I see what you mean, and no it doesn't allow it anymore.

I never used that trick before, as I've never done a clay tile roof, but I can certainly see where it had been useful.

Wonder what would happen to a project started in 2008 with those sweeps applied, and then upgraded to 2009?

*edit* just tried it, and it comes into 2009 with the fascia sweeos I created along the hips and ridges in 2008. I can select the sweeps, edit their end points or mitering options, even apply more sweeps to the edges of the existing sweeps. However if I delete one, I cannot put it back. That is quite odd.

Reminds me of when the factory disabled the view number on the sheet from legend views in version 9 I think. We already had a legend on a sheet with a number in our template, and when we upgraded the template, the legend remained on the sheet with the number, but when the view title was selected, the number could not be changed. If the legend was deleted then re-placed on the sheet, it came in with no number at all.

I've got lots of them and they upgrade OK and can even be edited in 2009..

but no new ones can be created.

Factory, is this a bug or is there any reason why it doesn't work anymore in RAC 2009?

Support request.

In the mean time you can use a line based family. I switched to using this object once it was introduced. Just a couple of days ago I had to put tivoli lighting at 8" oc around the roof and on the ridge. The line based family worked great.....

thanks Aaron - I must try that.

From a few things I've noticed I wonder if the different behaviours in some tools is just due to routines being rewritten and so this sort of accidental feature has not been carried over to 2009.

Just one of those things I guess.

...another thingh you might try is copying the same roof up just an inch or so. Then cut away everything but the ridge caps... Goofy, but parametric and it looks good.

Also related, a fascia can still be applied to any model line - on a roof or not. So you could daw linework in the roof and then apply the fasic to those.

Aaron just further your suggestion about Roof ridges. What I have found out recently from someone else is just copy the roof up and instead of editing the roof just use the opening tool to cut out what you dont need.
