Roof is unable to join - misses target!

[aliraza124543]

Hey there,

I'm getting this error message "Part of the roof to be joined misses the target face". Here are some of the screenshots attached. If anyone can assist in this regard that would be highly appreciated. Thanks!

Match the slopes

[aliraza124543]

The slope of both roof is similar. Actually the one you labelled as "1" is about 300mm above the other one.

disregard previous post

Lower the plate height of the Roof so that eaves are aligned -- or change the Slope. An offset Roof will need a different pitch to be able to join with the others.

Thanks @kadmonkee for your time. Actually I have tried it with a single roof and it works pretty fine. But as stated earlier this model has certain portion with ceiling above the rest. If you can see in the file attached the Media,WIR & BATH should be 300mm above the rest. And it wont attach as a single roof rather displays error.

Here is the file attached. If you can find solution to it kindly let me know, it would really worth it.

Thanks

Thanks @barthbradley , can you kindly check the file shared above. Actually I have tried a lot over this, if you can suggest over it that would be greatly appreciated!

How could they possibly join?

[kadmonkee · Accepted solution]

if it is all based on ceiling height then raise the roof to be a single roof and lower the ceilings where it applies.

make all your exterior walls the same height regardless of ceiling height.

maintain typical top plate heights and you will save yourself some modeling issues

you are also creating some valleys where you don't really want them

Like this?

You can join a lower roof to a higher one... not vice versa. If you want to keep it higher, edit it and extend the sketch line

[aliraza124543]

@barthbradleyyes I understand it misses the target. Is there something that would work just to make the roof intact...

[aliraza124543]

@ToanDNThanks but it has same elevation as rest of the house. I want it to be elevated around 300mm.

[aliraza124543]

@RDAOUI have tried it now but it didn't work, can you show me how to do it?

Sure. There's been a bunch of suggestions here. All viable.  It's just a matter of what you, as the designer, likes.  This is a design challenge. What we're paid the "big bucks" to solve.  😉

Then you cannot use Roof Join tool because the North plane of porch roof is outside of the main roof plane.  You would need a vertical drop to connect the two roofs.  

Or something like this.

It is a geometry issue, not a Revit issue.  You would need to solve the design of your roofs.

Thanks @kadmonkee , I am amazed with the suggestion, but to be very honest there are two distinct roofs that needs to be intact elsewise your suggestion was worth it...

[barthbradley · Accepted solution]

Personally, I'd align all the eaves (e.g. keep the same plate height).   Why the offset to begin with?  Maybe that's the thing you ought to deal with differently.  For instance, is it more ceiling height you are looking for?  Maybe a vaulted or volume ceiling could be framed with trusses.  You wouldn't need to offset the plate height to do that.

Thanks @barthbradley , will be desperately waiting for its solution 🙂

Solution: One Roof. Scissor Trusses over the portion of the home you want to have a higher ceiling.
