Angled Roof Over Stair

Recommended Posts

So, I had a little commercial remodel where the client wanted something like this (which I am not recommending they do for a number of reasons) but it was just kind of interesting trying to get this to work.  What I can't quite figure out is why the post to beam (rail with Follow Stair checked) rebuilds way above the roof planes.  Raise or lower the roof planes, and the top of the beams follow at the same height.  No roof definition so not based on a ceiling height.  What is determining the height that the tops of the beams rebuild to?

I believe the stairs need to be enclosed in a "room", or the rails adjust to the connected room characteristics.  From memory, haven't tested/used recently.

I copied all of the items to the right.

 

Made a "room" with invisible walls. That way you can control the height of the top beam.

Also changed the roofs so the baseline was parallel to the stair run and adjusted the baseline angle to match the stairs.  Your roof method works i just offered a different option.   

 

The top beam should solely be driven by the ceiling ht. of the room. 

 

Revised plan attached.

I watched a video on this type of covered walkway a while back and they used Mark's method of the Angled/Parallel baseline

 

can't quite remember whether here or ChiefExperts or ???  sorry.

Messed around with it for a bit.  Not sure where it gets those default heights from.  Must be some internal thing within Chief.  If you go into the elevation and make that wall longer and shorter it does some strange things.  Without a defined room, it must be defaulting to some internal algorithm.

Interesting method, thanks Mark.  I never paid a bit of attention to that baseline angle option on the roof dbx. Now I know what you can use it for.  Pitch and pitch direction are also correct for the roof planes, as opposed to the method I used.

      I know this discussion has been discussed before but I am having an issue with the roofs overhangs.  I have not had this issue before as most of the time the Boxed overhangs have worked but not this time.  I have tried everything in the book to make my overhangs boxed and nothing is working.  Any idea why my overhangs will show a boxed overhang?

      I want to add a porch and roof and meet an existing root at specific location. How to I specify the specific location?
      See attach. I've fixed the location of the dormer. The porch roof (shed type) needs to end here and on top of the porch beam.  The pitch is what ever it needs to be. I tried to specify two pitches on the porch wall, but I don't distance from the porch wall to the a point just in front of the dormer.
      I tried to move the baseline up on the main roof thinking Chief would tell me the height and then I could change the ridge height of the porch roof to match. I couldn't get it to work.

      I have designed a pergola and a deck. I cannot get the terrian to show right. It needs to be zero of level at back of deck by pool deck and slowly slope down to a bayou. it needs to be 36" to grade at edge of outer deck Then a stair going down to the end of stair which is around 5 fr lower that top of deck. I have not did much terrian and would appreciate your help. This is just a remodeling and adding a deck from the pool. 
       
      Thank  you,
