Roof Fascia clean up

Anonymous — Tue, 23 May 2023 12:40:28 GMT

i noticed that when I'm using the Geometry Method: Polygonal and I've selected the Perpendicular roof edge. The fascias do not clean up. If I use the vertical edge it works fine. Is there a work around for this or am I missing something. See attachment

What's shown in your screenshot usually indicates some other modeling error - roofs not properly joined, fascia angles different, etc...

Use the pet palette in edge offset mode to pull the hip ridge back for each of the two roof planes.

Verify that each plane is set to the desired edge condition.

Select one roof and control (cmd Mac) click on the hip edge of the the other roof. Reverse the process to complete the healing / join. Should be fine now.

Cheers,
Karl

Hi Karl,
Thanks for your response. The snap shot I sent was of a simple square with a hip roof. All four corners have the exact same characteristics. I zoomed in to each corner and they all match perfectly. The pitch 6:12 with the degree, minutes and seconds exactly the same. All four roof plans are of the same thickness and elevation. If there was a modeling error wouldn't it effect the fascias for a vertical edge as well which shows correctly when set to that edge configuration???

You'd think it would clean itself up, but what you show is what often happens when changing the roof edge angle after the first clean-up, in versions (such as yours) before the new roof tool that arrived in 15.

Thanks for the update. I guess it's live with it or update.

No need to live with it... it cleans up easily in your version ... you just have to either model it right the first time, or do the steps I gave for re-cleaning the roofs. Takes 10 seconds per corner.

If I wasn't clear about how to fix it, please ask again - and maybe attach an MOD file of your roof and one of us will clean it up for you.

Cheers,
Karl

Just reset the roof edge Angle. If it is set to the angle you want but shows incorrectly, then set it to another angle choice and then put it back to the one you want.
Toggling settings like this often rights Archicad.

Tried Erika's suggustion of changing eave angle and then change back with no success. I'm trying to send a .mod file and I'm not having much success with that either.

You need to zip the mod file to attach it... should contain only your roofs to keep the size small... select the roofs, save-selection-as...

here's the roofs in zip format. Hope you can do something with them

Thanks

Got your mod file.
Karl's original solution resolves the problem. Move the roof hip edges away from each other and the re-adjust them to meet.

Robert,

The steps in my original suggestion work just fine as Erika says. See attached steps. Screenshots from AC 12, since that's what you're using - but the steps are the same in all versions since at least 6.5 when I first started using AC.

Cheers,
Karl

PS I've seen this kind of thing happen a lot prior to 15 when the roof pitch is changed after modeling the roofs. Any time the pitch is changed, every roof that joins another roof must be readjusted with the steps shown in the attached screenshot so that the roof planes clean up properly in sections and elevations. With 15 and above's multiplane roofs, you can change the pitch and the entire assembly adjusts itself.

Here's a section through your hip, showing what I meant in my "PS": the roof planes were not properly joined in the first place, hence the sections would all be incorrect and you got the fascia problem also.

With gable roofs, you'll see these bad 'joints' in elevation, too. Just requires deligence to keep them clean after any modifications (by the steps given in the last post)... or an upgrade to 15 or 16.

Cheers,
Karl

PS Off topic: Haven't opened 12 in a while - was really surprised how slow it is on my Mac compared to 15 and 16. GS has really done some performance tuning.

Karl and Erika,
I'm grateful for all your help. I'll rework the roofs as you suggested.

Thanks again.
Robert
