Roof Challenge

[Alexis]

Hi, each and all,
Herewith attached is some curved lower end of roof that i cannot seem to figure out.
Is this really CHEAPLY obtainable in chief? [Note the capital letters]
And what is the right procedure?

[Gene Davis]

Of course it is possible. May we have some information from you, as in the version of Chief Architect you use, maybe a little about your PC system, and most importantly, whether you have ever watched a training video.

[Alexis]

Davis, thanks for the bother.
Your reply makes it seem like i asked something so obvious.
Anyway, i've used chief since x1 and am currently using x4.
As per whether i've ever watched any training video, hm ...... yes sir and i have over 10GB of videos from chieftutor.com
Anyway, i've tried to make arcs then turned them into moulding plines but this makes the moulding protrude beyond the slanting roof surface.
In the picture, the mould kinda slants with the roof. and thats my problem sir.

Alexis,
Maybe Gene stubbed his toe this morning... ? (though, in addition to your computer specifics we'll need your ssn # and credit card info...)

I'm having trouble figuring out if that roof form is geometrically possible. If it is one of two things must be happening - the roof is curved along with each arch or the overhang must project further at the low points of each arch. It does not appear that either of these are occurring in the rendering.

[Joe Carrick]

It would appear by looking at your pic that the Arches are just built in front of the roof planes. It's likely that the roof planes actually terminate at the exterior wall (no overhang) and that the arches are either like parapet walls or their tops continue back to the roof surface.

Maybe those observations will give you some ideas.

You're correct. It's two roof sections.

A barrel shaped dormer (with no pitch) which ties into the sloped facet of the cone shaped roof.

Somebody with skills could make a 3d molding for each barrel and position a section right in front of each roof plane on the tower.

[David J. Potter]

I agree with Joe, in that roof baselines cannot be curved or broken, rather they are straight in Chief. Your Roof plane's baselines in the image are curved in the "z" axis. So if it were my modeling problem, I would make the roof planes straight at the bottom and then fill in with poly-line solids, 3-D molding poly-lines to get a near appearance to what your image shows.

I suppose you could get a Chief roof plane close, export to Sketch Up, alter to suit in Sketch Up and re-import into X4, whether or not that is "Easy" or not, you would have to decide.

I don't think it can be dormers. You'd see the top of the vault in the image (unless plan book renderings tell lies...)
I had to resort to sketchup to mess with this geometry.

[Gene Davis]

Chief cannot do a warped roof, like the picture might seem to depict, but it can certainly do a curved roof, as in a barrel-type, then join that curved roof to a planar segment. I see that building as being emulated with witches-hat segments, easily done, and at the bottom of each segment, a short barrel does an intersect. The front edge of the barrel is dressed with a 3D molding polyline.

Sorry to have offended you, Alexis, but with 26 posts and no signature line, and no way to know your package, you seemed like a newbie.

From an old practice file that does not translate well when I open it in X5 ('twas begun in V10), here is a pair of curved roofs, one a small fillet, intersecting a planar section. A 3D molding is at the edge. Chief can do your roof for you. Grab your mouse, and start, now.

I think it's what you're looking for.

[yusuf]

Intersect it with curved poly line, and convert curve to poly line, this is the way we can do in ca.
Plan too large to attach ,but clear i hope.

[Gene Davis]

Methinks you want the lookouts, i.e., the little barrel sections sticking out. It was quicker for me to doodle it in Sketchup, but here it is. More involved in Chief, but hey, you can do it.

[VHampton]

You can fake it with a molding poly-line.

You can fake it with a molding poly-line.

like it!
Really verry nice immitation. what works works

[VHampton]

Thanks Yusuf.

The real life photo is a slight trick of the eye because it appears as if the roof only had slices taken out of it and then the elliptical medallion was set into place. The medallion needs a roof as well. A barrel shaped one.

When I say "fake it" what I mean is that the barrel roof section wasn't made with a roof.
