Roof Tool - Barrel Vault

Vitruvius — Tue, 23 May 2023 13:29:41 GMT

I've just started on AC 10 and am creating a barrel vaulted roof.

I was kind of hoping Graphisoft would get their act together and allow us to eliminate the interior lines - this tool still behaves like something out of 1996. Is there a way to turn off those lines?

you are right mate, it still sucks in AC10...

You mean like Maxonform?

No, not like Maxonform.

I'd like a smooth barrel vault which displays like an ArchiCAD curved wall - ie. its not rendered like a bunch of segments.

It should be sooooo easy for GS to fix this longstanding LAME implementation.

Please GS...

Still lame but here is how I did it on a huge house with 10 barrel dormers recently:

1) use very small segments (magic wand settings)
2) set the internal segments to a white pen.
3) set the outer most segments to a printing pen
4) use a ring-like part from the basic shapes in the Library for the facia.

This way it is possible to get something that looks OK in plan and section/3d

Total hack........

Lots of people will tell you that SEO's are the way to go but then you never get it right in plan.

One option is to not use the roof tool and build it using profiler and solid element operations...

Can you use the V10 profiler of the wall tool?

Okay, try this:

Draw a curved wall. Save as a GDL object, carefully selecting your viewpoint so that it is created from a "plan view" of the future roof.

Place object. It will be nice and stretchy and take maybe 30 sec. to create, once you understand the process.

I posted this thought somewhere else today: Any reason why you could not make a Profile out of that, then draw it with the beam or wall tools?

Or what about the parametric primitive "Conoid?"

Great name.

I just tried this. Only issue is that top & bottom materials are hard to control. (I don't know if it's a bug, or what, but I could only get the end materials to change.)

Doesn't that require the consumption of mass quantities? But I don't think they'd like being called primitive.

Using complex profiles doesn't eliminate the problem. You'll still get a segmented profile [Edit: in shading mode], even if it does have less segments.

We all hear what Cameron is saying though, and what the common wish is - GS give us true curves for all the tools in ArchiCAD!

Yes please. Been trying to build a curved walkway with a sloping roof butting up to a curved wall. Ended up just doing it with lots of small controllable roof facets. Not perfect but good enough for now.

The Mesh to Roof add-on wasn't suited to the task? Still nowhere near as good as true curves though!

Hadn't thought of that. But this is my result - about 12 facets between each pair of columns, and reasonably easy to edit at junctions with other roofs......

S t u a r t,
Why didn't you use the mesh tool to make this kind of roof ?
(see attachment)
Also, how did you hide the edges of each of the 12 rooflets ?

If you don't mind me asking.

Oh I see the shape you were trying to create now. Yes, Mesh to Roof is probably not the best solution there - too many planes.

A simple mesh would have done the job, like Peter said, although I doubt it would have given you very good material texture control.

If only it were easier!

Thanks for the input - seems the consensus is that this tool doesn't work!!

I experimented with the various fiddles and I think the 'wall fudge' suggested by Aussie John wins. Attached is a complex profile wall with an opening inserted. I'll still have to create a custom opening with sill/head perpendicular to the ground rather than parallel to it but as a fudge it works.

Note that on the AC Barrel Vault the segment lines don't appear on the fascia - so GS has halfway addressed the problem. How about taking this one over the finish line GS?

Cheers.

Peter,

I hadn't thought to use the mesh tool as I have found it difficult to manipulate in the past (although I am getting more familiar with it), and hadn't realised I could curve the edges to get the shape I wanted. Now I know, I'll give it a go!

Thanks for the heads-up.

EDIT: Ah, but as Link points out, texture control will be an issue (asphaltic shingles, really need to have them follow the roof plane).

(And I had simply shown contours "off" in the OpenGL 3D window)
