Sawtooth shed (skillion) roofs

Recommended Posts

Hello,

 

I'm new to the forum (first post) so I apologise if my unsuccessful searches have missed this.

 

I'm trying to create a sawtooth roof, with each roof being a skillion (shed), so that the middle wall forms the high edge of one roof plane and also the low edge of the next roof plane.  

 

I've read and successfully implemented the excellent Knowledge Base article on multiple shed roofs but can't figure out how to have the middle wall do double duty like this.

 

Thanks for any suggestions.

 

Matt

It helps if we know what title (Suite, Pro etc) and version (2014, 2015 etc) you are using. You can add this info to your signature by clicking on your user name at the top right of the page, click My Settings, then Signature on the left.

If this is an existing structure you are modeling, could you post a picture?

 

My guess is that you will need to build separate buildings with a shed roof on each, then with auto rebuild roofs off, move them together. Deleting the extra common wall.

 

Start by drawing a long space, then break the walls and pull apart to create two spaces. This will insure the walls align when you move them back together.

When the roof is correct, turn off 'auto build roof '.

The interior walls can then be removed, if desired.

Thanks all for your suggestions.  Sorry for my delay in responding - this is a weekends-only thing for me.

No Solver it's not an existing structure but the image shown in Jo-Ann's post is exactly what I'm after.

The Clerestory KBA method is working for me, except that I'm having trouble getting the elevated bit of wall which joins the two roof pitches to work correctly or at all.  (That is, the wall above the left hand one of the two inner temporary walls.)

Jo-Ann, you've solved it but I don't know how.  I may be not using the forum controls correctly but all I can see of your post is the last 2 lines and two thumbnails.  Tantalising!  

How did you get the wall to draw?

I only posted 2 lines.  The details were in the thumbnail.

 

Post a pic showing the problem,  so that somebody can help.

Oh, righto.

Thanks Jo Ann.

I'm leaving the project for a bit because our plans may have changed radically - renovate existing rather than demolish and build afresh - but I'll post an image if/when I come back to it.

Thanks again for your help.

All the best.

In the UK we used to call those types of roofs North Lights.  I worked as an engineer at Austin-Morris in Longbridge and what we referred to as the North Works had the same roof structure.  I believe it was designed to capture as much North light as possible but the roof at Austin-Morris faced west - go figure.
