Custom Fascia Profile Issues

[Anonymous]

So I created a custom roof drip edge, applied as fascia - thx to @ToanDN for the initial screencast on how to do this. You can find it here: https://forums.autodesk.com/t5/revit-architecture-forum/custom-fascia-profiles/m-p/6794027/highlight...

I have a couple of issues:

1. The fascia is applied to a roof that has a slight slope. It applies fine on 3 sides but on the backside (low side of the slope) it is applied flat in line with the roof plane rather than applied to the fascia side and I cannot seem to edit it. Any ideas why this is happening and how I can work around it? Tried to make it editable and rotate it with no luck.
   
   
   
   
   
2. Is there a way to get a clean joint at the corners for a profile like this? I tried the "join" function but that does not get a good result.

You should able to create one continuous fascia by picking the 4 edges.  Do that and it should answer both of your questions.

OK. I got that figured out now but have another related problem, so I'll continue this post...

This small sauna building has metal cladding, so I have added a fascia board on top of the siding so the custom drip edge can be applied to a solid underlayment. The fascia is a closed loop. I now try to add the Drip edge to the fascia and have a similar issue. I can apply it as another "fascia" with the custom profile but now again (even when selecting continue fascia,) I get the corner connection issues again. My other issue is that I need to create a second roof for my TPO layer but for some reason I can't do a roof by footprint or a roof by face, only a roof by extrusion which makes me pick a level and create a roof as shown below. I can't seem to modify that. What is the correct way to apply a "second" roof to a sloped roof?

I forgot to mention that I never really figured out how to select all four edges, I used the "continue fascia" command. I watched your video again sveral times and it appreared you used the TAB button to select all edges, but that does not work for me.

Can you share the file?

PM'ed you the download link.

Now I see a fascia with a custom profile can't quite miter nicely.  You may want to use a model in place sweep.  Since the sweep path is not flat you need a small trick to keep the sweep from twisted when it turns.  I cannot do it now since I am re-installing Revit to my laptop at the moment but I can show you sometime tomorrow.

Regarding the thin roof atop, I don't understand why you can't draw it by boundary?  Or, simply copy paste the main roof in place, move the copy a but up, change the roof type, and edit and offset the boundary to size.

@Anonymous hello, here is the screencast, you can modify the sweep profile for your design of fascia. thanks

[ToanDN]

@ennujozlagam

Try it with a sloped roof.

[ennujozlagam]

@ToanDN hello, here the screencast. is this you wanted it to be with slanted roof? thanks

[ennujozlagam]

@ToanDN hello, It will not work on a slope roof following the sloped. thanks 

[ToanDN]

Yes. Do you see the profile got deformed? Cut 2 sections thru the roof you can see more clear.

So the weird thing is that the T-drip joins fine if there's no fascia board underneath it. As soon as I place the fascia board first, the T-drip will not join in the corners.

@ToanDN - your suggestion of copying the original roof and then changing it worked - thx for that. Did not think of that workaround. The create roof by footprint for some reason does not work. I'm gonna try a few other things on the fascia issue. Let me know if you guys come up with something.

@ennujozlagam Thx for the screencasts.

I would suggest draw the fascia board as a model in place sweep.  The reasons are (1) the profile is simple rectangle so if it is deformed it is not noticeable, (2) it is behind the T-drip so some imperfection shouldn't be an issue, (3) you can even create 4 separate sweeps for the 4 edges and that guarantee no deform occurs.  

(If it was me I wouldn't even bother model these invisible boards)

Then model the T-drip using fascia tool and pick 4 edges the corners will join nicely.

So I ended up not modeling the fascia board, just pulling the roof surface out flush with the metal panels and then attaching the T-Drip to that. This worked fine and got the job done. Out of curiosity, I tried to follow your advice and modeled the fascia board as a sweep and then tried to attach the T-Drip to that. For some reason it will not let me attach to the outside edge of the sweep profile. Could it be that a fascia can only attach to a roof or another fascia and not to custom sweep profile?

Your assumption is correct. Fascia can only host by roofs and subcategories of roofs. What I meant was you using the edges of the main roof to host the t drip, but offset the profile 1" out.

Ahhh - got it. That works beautifully. Thx again @ToanDN.

Btw - for anyone else following this... the fascia offset has to be set in properties. Cannot be done with offset command. See screenshots below.
