Creating multiple shed-roof sections all sloping up from back to front

Recommended Posts

Attached is my Grande Projecte.

The planned roofing is 3 segments of shed, sloping up from the back, so the back wall is 12ft high, and the front window wall is 20.

 

The 2 wing sections will be separate sheds, also both sloping up back to front, with the break line 35 ft back from the front wall -- yes, I know I have to adjust the rooms on the right.
 

Can anyone give me some pointers on how to talk HDPro16 into doing those 5 shed roofs?  :-)  Is there any video on complex multi-sheds anywhere?

What is the forum doing that is stopping you? No limit that I know of.

That's not quite informative enough, is it?

The left, center and right sections will be independent shed roofs.  Center is a single shed, from back up to front.

The left and right sections will have a shed from the back wall to the wall that's 35ft in from the front, drop down to the ceiling line with a window, and a second shed up to the front.  Some of these elevations, obviously, are subject to some tweaking, once I have the basic shape in place.

The software said so; I tried to set it to 450, and it said "no larger than 150".

It did *not* say "size of the thumbnail", which is what it meant.  Fixed.

Yes, JoAnn, exactly that. 

Well, almost exactly; my original design didn't have the rear halves of the side roofs be part of the rear half of the center one, but that's certainly close enough for government work.

Is this, as I suspect, mostly a creature of properly splitting the cross walls, and marking the proper walls as Shed and Gable?  Or is it more complicated than that?

This is done using manual roof planes.  Start practicing.

Was the center section intended to be raised or lowered from the sides?  Not enough information.

As in your sample, all 3 segments of the roof are intended to be anchored to the back wall, and raise up from there.

Excellent chance your notes are enough hint to get me there, I suspect.  I'll try it tonight, and thanks.

Here is another example.

 

Once you get familiar with the manual planes and how they intersect / react with the walls, it will get easier to modify your roof.

I DO hope that you post a jpg of the finished roof, when you're done.

Oh, of course; I know the rules of free help.  :-)

Now I just have to figure out how those walls in the middle can have a height of both 12 and 16 feet simultaneously.  :-)

They are attic walls, and they usually generate automatically.

Hmmm.

Based on that and something in DJP's video... do I have to put in a fake second floor to make *any* of this work the way I want, then?

Well, stage one: I got a single plane, even though I broke the rear wall.

Clearly, the part that requires manual roof plane setting is that one is not permitted to set the heights of the front walls manually otherwise. 

Off to read the articles in David's search.  Maybe some caffeine first.  ;-)

In Architectural you raise roof planes by setting the Ceiling Height higher in the "Room Specification Dialogs- Structure Tab - Ceiling Height" enough to achieve your target Roof Height (they, Ceiling Height and Roof Height in Architectural are pretty much the same settings for all practical purposes).

 

Adjusting the "pitch" of a roof plane is done in the "Wall Specification Dialog - Roof Tab - Roof Pitch Input box) under the roof plane you wish to control, pitch-wise (its relative height is due to two factors: its pitch and its baseline height which is caused by the Room Dialog Box - Structure Tab - Ceiling height setting
