Unnecessary ridge added to roof

Nora — Mon, 19 Sep 2022 03:04:04 GMT

Hi there,

I've been having some problems with my roof

It keeps adding a ridge when it isn't necessary

I've deleted it and redid the roof just to be sure it wasn't a one-time thing but it didn't solve anything. The ridge is still there.

And it's really messing up with the roof covering

Has anyone ever had this problem?

Is it a multi-plane roof or single roof planes?

I am guessing something is not quite square?

What happens if you remove just the roof over the stairs?

Does that front surface become just one plane or is there still some kind of break.

In the elevation, the ridge to the right seems a little lower?

It is hard to say with the accessories showing.

Barry.

Hi, I noticed that the valley line on the RHS over the stairs, goes all the way up to other ridge for some reason ?

Have you tried deleting the whole roof and then use the magic wand to create a new one yet ?

Otherwise you can just edit that roof plane that has the out of place valley and make sure it stops at the point where the LHS valley intersects over the middle wall between the stairs.

Hi Barry,

Yes, the walls were 0.1+mm off from each other that's why it was creating the ridge.

Wow ! Archicad is quite precise but in the real world those walls can be out by allowable tolerances and it would not affect how the roof framer would build it.

Thankfully Barry has lots of experience with the program for him to pick that up.

I will remember this if my roofs don’t build correctly in the future.

But I always set my buildings out with active dimensions while drawing them up so that I can avoid those types of errors.
