Round Roof - how to make "radial ridge lines" not show up?

rob2218 — Tue, 23 May 2023 12:27:17 GMT

see attached.
basically been asked to make the "radial ridges" of the rounded roof portion disappear....how do I do that?

Lots of white lines.

Or cut out that section of the roof and use a SHELL in its place.
You can get a smooth curve with a shell.

Or if your roof is not going to change convert it to a MORPH and you can hide those edges.

geez....really?
hubboy....lots of "white" lines meaning...do I have to draw a "2D line" on top of those "ridge" lines? you're kidding me right.....

A morph? no way...this is a remodel (meaning existing, new, demo) so the roof will get very very messy very very quick if I create this thing into a morph.

A shell huh.....hum.....wonder what I can do there?
I haven't used the shell command that much and quite frankly I'm a bit lost with how to use the shell tool to create a smoothed, rounded roof like this.
particularly when this roof intersects into a normal "ridge and gable" roof...

Or possibly the best is to split the roof into single roof planes.
Select just the curved portion and convert that to morphs.
Union them together into one morph and then hide the ridges.

Or turn the roof layer off in plan and just draw lines exactly where you want them.

GEEZ.....I think 2D autocad is looking better and better again.
Really guys....turn the roof off and "draw" 2D lines where you want them?
come on......there's got to be a better solution than 2D white lines, morphed 1/2 baked shapes, and 2d roof lines....please.

but if I morph the two roofs and "turn off (hidden edges)" the ridges...then ALL the roof ridges including the correct ones..will disappear...won't they?

With a morph you can select the individual edges so long as you use the alternate selection method (white selection arrow) - CTRL+SHIFT (CMD+SHIFT?) is the keyboard shortcut.

If you select the entire morph then yes all edges will be hidden - you will still see the perimeter in plan.

is there a "step by step" on how best to use the "shell tool" to create a 'revolved surface'?
I'd like to test the shell tool on this roof.

go to the Help Centre. search shell and then navigate through the tree on the right hand side. there are several that would be helpful.

There are a lot of short movies on the shell tool in the Archicad YouTube channel.
Link is in the HELP menu.

Create a simple 'Revolved' shell using your roof to set the radius.
This will create a dome but then in 3D select the shell and click on the curve profile line of the dome shape to bring up the pet palette.
Choose the 'Add node' option and the curve will become a straight edge.
Now all you need to do is elevate the shell to match the height of your roof eaves and adjust the apex to match the height of your ridge.

You can use the same composite as your roof - just make sure in the composite settings that the button is set to allow it to be used in a shell otherwise you won't find that composite.

for some reason beyond me knowledge base....I can't seem to get the hang of the shell tool for making this "simple" radius curved roof.

It'd be nice to be able to use a "composite" which I see you can do but...for some reason I'm not getting the right steps on quite how to make this simple slanted, curved roof.

First step is to make sure your roof composite is available to the shell tool.
Press the shell button in the composites settings for the roof composite you want to use.

Now model a revolved shell with your roof composite.
Don't worry about the height yet and use the roof to set the radius and start and end points of the shell revolve.

Select the shell in 3D and make the curved profile straight by adding a node to it.

Barry.

Barry Kelly — Fri, 13 Mar 2015 02:31:29 GMT

Now elevate the shell to match the roof and drag the op apex down to match the roof ridge.

Barry...your explanation make it sound "so" simple sir....I hope you are an Archicad instructor where ever you reside.
I'll give it a whirl.

Split the roof into single roof planes and delete bits you don't need now.
You will still have joining lines in plan and elevation but that is because you can't turn of the end lines of the roof or the shell.
That is where the morph comes in handy.

Barry.
