Bell Roof

-Hi Yusuf,

Here's a question which someone else might be able to answer.

Can a roof be made into a symbol?

If yes, then the solution could be as simple as taking this type of roof, (half a roof as shown) and exporting it as a symbol.

Upon entry into the plan the symbol could squeezed in the front to back dimension.

Then it could sit over the ellipse perfectly.

-Hi Yusuf,

Can a roof be made into a symbol?

The answer is yes. Anything you can display in 3D can be made into a symbol.

The ansewer is yes!! Dear mr hampton even a glass pyramid symbol i created by roof.

Oh joe i would have just be standing if i knew you were righting.
Surprizingly you were lost after the nice talks.
Nice to c you here again.

[yusuf]

Oh joe, come on you came again with the ramsus ¡¡ homes in egypt(pyramids) surprizing.
I didnt know you were righting at the background.

First off thanks everyone for chipping in here. The way I first started trying matches what Val has shown - but like Val I could not then get it to the next level with compound curves. Its also possible that chief CANT do this - and maybe sketchup can but I am not fluent (or even passable) in SU.

So I am thinking the only solution is to spend the time working with a solid and subtracting strategic areas. Hmmm.....

Rich,

If a roof with the correct height, curvature and circumference were generated (as per Yusuf's post) the thing should be able to be made into a symbol.

It could be positioned it over the elipse and squashed in the x y axis until the overhang looks about right.

I've used cones out of the geometric shape library to place on top of round towers. The facets on auto generated roofs are way too busy on the 2D elevations and the cone helps clean all of that mess up once it was assigned the shingle texture. In theory what you'd be doing is very similar.

The problem is I have zero experience in symbol making. Maybe one of the 3D wizards can assist.

Change the design. What you are trying to do would be hard to build. The crew would complain about the designer and in this case the complaint would be justified. This would require warping each segment across multiple axises. Plywood does not like to do this. Look close at the picture from the OP. Check out the far left side of this roof. They couldn't build it either. The left side turns into a totally different roof plane. This is a fun exercise in computer what ifs and I'm enjoying the various ideas but if you want any repeat business from this client, change it to something that can be built more easily. I'm not saying it would be impossible to build, just very impractical. Just my 2 cents. Carry on.

What are the dimensions of this roof or the room below?

Give this a try... it may not look exactly the same, but I tried to get it close. I had to create the ribs manually since there are so many triangles (because of the curve) you couldn't get a texture to generate correctly on it.

I've included the Sketchup file and the .3ds file.

Import it as a exterior fixture. I tried it in CA and it works great. It resizes really nicely too.
Enjoy.

Nice, Aaron. What plug-in did you use to loft the surface? Curviloft? How about the ribs?

And for sure, Chiefers, don't roof this with anything other than a smooth no-texture material. Copper it is, and copper it will be. But just for grins, try roofing it with shingles and watch what the ridge caps do.

[amddrafting]

It wasn't a plug-in it was manually created.

1.First I drew a line at 6' long
2.Second line was from the midpoint of the first line vertical 1/2" the length of the first line
3.Then I set an arch to bulge from the endpoints of the first line 1/2" the length of the vertical line
4. [see first picture] Then I drew an arch from the top of the vertical line to each segment of the original arch. Once connected I drag the mouse down the vertical line until it snaps to "Tangent at Vertex" and set it there. Each arch should be drawn this way. I only do this for 1/2 of the bell curve as I will mirror the whole thing later.
5. I then trim off the top a bit since in the real world nothing would come to that perfect point.
6. [See second picture] Then I go and connect each endpoint in the vertical arches in a horizontal orientation. Once those are connected I draw a line from one corner to the opposite corner and it creates a planar surface.
7. Once I did that for each one I selected the whole object and copied and mirrored it and then connected the whole thing and made it a component so I wouldn't screw it up working on the ribs. Oh and select the whole thing, right click and select smooth normals and it will get rid of all of the vertices.
8. For the ribs I created an arch from each point in the component top to bottom just like step 4.
9. At the base of the arch I drew a vertical line 1/2" high
10. Then with the arched selected I used the offset too and followed the vertical line I drew.
11. then I connected to top of the two arches to close the surface.
12. Then I extruded each side of the surface 1/16" in each direction.
13. Then just create a cap to go on top and place it there.
14. Then I also drew an arch at the bottom but I set the segments to 100 so it looked more round. I offset it, connected it, and extruded it 1" to be the lip at the bottom.

That's pretty much it.

[Dave Pitman]

That's pretty much it.

Easy for you to say, Aaron. Good Job.

[Gene Davis]

Wow, Aaron! You skinned it by hand. The roofers are impressed. Thanks for the feedback.
