Hello!
I have a problem with roof.
Trying to modify the roof inclination with Inclination lines but if put values with level can't do it (level 2 to leve 3).
If put insted inclination with degree (60°) and arrived even beyond the roof height go.
Why?
Thank's

How do you want your roof to look like? Are you trying to match both roofs in height?
Yes.
And furthermore isn't there the possibility to create a roof put level base and top?
Is this what you wanted?
Have you checked the slope arrows settings in my previous post? Are they working for you?
I want to arrived at same height the roof for garret (in which are the slope arrow).
And I noticed that if put value in degree (30, 60°) the program go.
If il command "final external height" red square highlithed and put from level 2 to level 3, don't go.
Perhaps I don't understand the question, but going with the settings posted in my first post, I'm getting what you're after, right?
Is this what you are trying to achieve? Go to a side view, click on the roof. You will be able to drag the double-headed arrow that appears.
@Sahay_R thank's for share with me this possibility.
But wanted to maitenice those main height (16.71m).
Is not for resolve the problem because I undrestand that I can revoled modifying enter in the perimeter of the roof, go to the slope arrow and put the values in degree to arrived at the same level 16.71 m (level 5). is just to undrestand if can do the same with the command "height at tail" as @PijPiwo tryed to explain me with the post before, but with the values he said with me don't go.
However thank's. @Sahay_R. Didn't think that I can do also you recommend me if want to reduce the main hieght.
Interesting, but it looks like in the Italian version, slope arrow constraint options are reversed (?) - see picture. Am I right or my Italian needs some polishing
?
Rvt file enclosed.
Here is the reason why...
These two roofs are created by-footprint, and are sloped using slope arrows with the same height-at-head and height-at-tail values. Please note two things about this:
1. The slope arrows define heights UNDER the bottom of the roof structure, and...
2. ...the THICKNESS of the roof structure is NORMAL TO the roof regardless of its slope.
So, geometrically, the result of two roofs defined in all ways the same except for the distance of the slope arrows (and thus the actual slope of the roof) is that they have different top peak heights. Look at the picture above. They line up under the peak, but not on top of it. That is just how geometry works. The real solution, in my opinion, should be as follows:
1. Do the math, or measure after the fact, to determine how much you need to offset one of the roofs to line up the top of the peaks, or most easily in fact, just use the move tool to bring one in line with the other, and then...
2. ...get the eaves aligned by changing the plumb cuts, or just voiding the elongated eave edges of the steeper roof, or using a fascia board sized to cover both properly, as would be done in the real world anyway.
@Anonymous, …and that’s where the offset at head (-0.2413) comes from as explained above by Chris.
If you're solving it by offsetting the slope arrows in the footprint sketch, you need to offset the heads AND the tails down 0.2413 or whatever, because both the peaks AND the edges at the fascia differ between the two roofs.
thank's @chrisplyler for the explanation.
I undrestand. Only a thing:
1. "2. ...the THICKNESS of the roof structure is NORMAL TO the roof regardless of its slope." ==> "normal to" what does it means? "is perpendicular"
2. "shift tool to bring it in line with the Other, " what is? can you do a screenshot plerase?
3. "get the eaves aligned by changing the plumb cuts, or just voiding the elongated eave edges of the steeper roof, or using a fascia board sized to cover both properly, as would be done in the real world anyway. ==> can do an attahcment please?
Thank's very much.
I undrestand the question. Have some problem to undrestand long tecnical sentences for my english..
However if click level base: 2 and level 4 = (level 4 - 0.2413 (thickness roof) don't go. Say me " impossibile to mainteine wall and object jointed"
if put level 4 -0.27 or 0.24 (for example) run correctly.
However though is more normal put the value on the top for the thickness (-0.37 cm), since inclination is so instead is 0.24.
@chrisplyler I reread the notice and undrestand
"So, geometrically, the result of two roofs defined in all ways the same except for the distance of the slope arrows (and thus the actual slope of the roof) is that they have different top peak heights.

About revit works
"1. Do the math, or measure after the fact, to determine how much you need to offset one of the roofs to line up the top of the peaks, or most easily in fact, just use the move tool to bring one in line with the other, and then..."
to alligned the roofs
"2. ...get the eaves aligned by changing the plumb cuts, or just voiding the elongated eave edges of the steeper roof, or using a fascia board sized to cover both properly, as would be done in the real world anyway."
to hide discontinuity for eaves or top of roof.
Sorry,
Only do not undrestand why 0.2413 for me don't go.
Cheers
It looks like revit doesn’t like having two ridges at the exact same height in this case. This is as close as I could get without getting an error - see pic. Use two separate roofs if you want precise match, but 0.12 mm of imperfection would definitely work for me.
Many times in revit, something needs to be tweaked in order to work.
Chris and Pij have both given you great advice and it seems like you understand. Hopefully these videos will clear up how what you are trying to do can be accomplished.

Good Luck!
