Curved Roof

Anonymous
Not applicable
I am trying to help someone else create a curved roof and ran into some difficulties. Any help or suggestions would be apprecicated. I will try to post some images (the part of the roof that is missing is where there is difficulty). The biggest problem is not in creating the roof, but in projecting the segments to the adjoining roofs.

Regards,

Dave

It depends on the particular shape of the roof you plan to use (it would help to see the intended form) but you can probably fit them up by control/command clicking the roof edges to join them. If you don't already know; select one roof and control/command click the edge of any other roof to extend it to the selected one. It is most fun to do this in 3D where you can see the immediate effect.

BTW: It looks like you may have some tricky crickets or a low-pitched or flat section to make those roofs work (i.e. not leak).
Someting like this Dave?

I've pasted the intended roof with a 3:12 pitch. The walls are the same height as adjacent area to left, but 2'4" lower than adjacent space to the right.

Any thoughts Steve or Matthew? My initial thought is to change the pitch or to raise the walls, but this may not be what client wants.

I'm also attaching a plan image and iso with the wall height raised 2'.
you can see how "funky" the roof starts to look.

plan starts to look really bad.

Dave,

You may want to rotate the roofs over the rounded walls so that their ridge will terminate in the valley between the high roof and the low roof. It looks to me like you know how to do it. Remember..."The customer is always right" so what if its butt ugly.

Dave,

For those few times when "Ctrl-Click" won't work to join your roof planes, view the roof in 3D (Internal Engine) Top view, select the Marquee Tool (last choice on the right from the InfoBox) surround the roof, Edit, Copy, and Paste a scaled drawing to the original locaton on your floor plan. The fills will show you where the true intersects are and you can stretch your roof nodes to match. This is also a good way to find the angles created when you are working with multiple pitch roofs or when you need to get the roof edges close enough to use "Ctrl-Click" to clean it up. Good luck with your roof.

I know this is OT but I just can't let it pass.

In professional practice the customer is not always right. Doctors, Lawyers, Architects, Engineers, etc. are hired for their expertise. Would you tell your attorney how to plead your case, or your surgeon how to proceed with an operation?

It is our job to meet the client's needs in a way that is consistent with good practice and quality of design. If the Architect doesn't fight for the integrity of the design it will inevitably be eroded until there is little of quality left in the project. If it becomes impossible to maintain the quality the client should be fired. If the Architect will not fight for his/her own design it's time to look for another line of work.

Please excuse my over-reaction to a lightly sarcastic remark, but I am sick of seeing the endless dreck of bad design all over this country.

Off the soap box now. Maybe I'll go rile things up at the pub later this evening.

Steve,
Nice tip about using the fills to find the intersection of roof planes
with different pitches.
I had been doing it the old pencil and paper way by measuring
the ridge to roof plane intersections in elevation.
THANKS!
