Problems with Wall trimming

mukster — Tue, 23 May 2023 13:12:48 GMT

I am having problems trimming a wall to a roof. The wall is a complex profile, shows up fine on the floor plan, but when I trim it to the roof, in 3D it disappears. The windows are still there, but the wall is gone. Shows up fine in plan view, but not 3D.

Please show us an image of the 3D window before the roof trim
and after the roof trim.
I have never seen windows without a host wall.
Could you also tell us your version number and platform.
Thank you,
Peter Devlin

Are there two separate roofs at different levels and its trimming to the wrong one? If so select the appropriate roof and the wall before doing the Trim operation.

Alternatively, use Solid Element Operation with roof as operator and wall as target (more common since AC9, maybe even 8 ? ) as it gets updated automatically if the operator moves, whereas Trim to Roof does not.

Archicad 11, Mac platform. I'm not sure how to capture a picture, I'm new to Mac and have been using Archicad only a few months. There are 2 roofs coming together at the ridge, and the wall on either side of the wall section in question (there are 3 sections to this wall - it's a timber home) have no problem trimming to the roof. It's just that when the trim to roof command is executed, the center section (where the roofs come together) disappears in 3D, but the windows are still there.

New to Mac too, Apple+Shift+4 and use the cursor to select the area you want captured.

okay - Picture 1 = before
picture 2 = After

Also, it's taking a VERY long time to perform the trim function

Picture 2 = after

There are many Keyboard Functions in Mac.

New users should review:

System Preferences> Keyboard and Mouse>Keyboard Shortcuts

I see Picture 1 but I do not see Picture 2.
Does anyone see Picture 2 ?

I've seen this happen and coincidentally it was with logs walls also. However it wasn't the log walls that were the issue, it was because the architect had used the wall as an operator and a target, so it was cancelling itself out. Are you using Solid Element Operations to trim your wall?

If so, I would use the Maintain Operations panel of that dialog to cancel the operators and targets, then be careful when re-trimming. Make sure only the wall is selected as a target and the two roofs are only selected as operators bfore doing your Subtraction with Upwards Extrusion.

Cheers,

Hello Link,
I tried selecting a wall, making it the target, selecting the same wall
and making it the operator, then tried all four SEO operations but all
I get is an error saying "no valid targets stored" and the wall
did not disappear. I would like to see what Mukster says he sees
which is apparently some roofs and other elements but windows
floating in air where a wall should be but is not. You say you have
seen this before and it was because the wall was used as an operator
and a target. Where there windows left floating in air ? How do you
get the wall to disappear without getting the error message I get ?
Thanks,
Peter Devlin

I may be doing something wrong on my end but I can't see the coursing lines in elevation view using the complex profiles. Which is one reason why we rarely use it. You can just as easily get what you are after using the Log Details settings in the wall tool and maybe composite walls. I don't think it would have any effect on your current issues, just an observation.

I have also seen this happen using SEOs (but not the Trim to Roof function). I don't know exactly what caused it, but I knew it was SEO related because the wall was visible in the Story Window, and invisible in all other Viewpoints (and, yes, the windows were there in 3D, floating in space). I canceled the SEOs and the wall reappeared.

Not much help, but I have witnessed the phenomenon...

Hello Laura,
That is amazing .
Floating windows and all.
Do you happen to remember which version of AC
you were using when you saw this effect ?
Thanks,
Peter Devlin

Re: Problems with Wall trimming

Laura Yanoviak — Fri, 29 Feb 2008 16:17:10 GMT

This was AC11, about 2 months ago...

Hello Laura,
Maybe that is why I can't reproduce this effect.
I am still in AC 10. Perhaps someone using AC 11
can confirm that making the same wall both
target and operator will cause the wall to disappear
leaving doors and windows behind.
I am reminded of an ancient Chinese saying which goes
The eye cannot see it's self, the sword cannot cut it's self.
But in AC 11.....
Thanks,

I have no idea what solid element operations are - our walls are a complex profile, and I'm using the trim to roof command. All the other walls are fine, just this one is causing a problem. When I move the wall 5' out from the building, it shows up just fine (properly trimmed and everything). When I move it back, it disappears. And, I can't get picture 2 to load up. What are the steps to loading a picture? Do I click on the filename, then add attachment button?

Click "Browse", select file, and then click the "Add Attachment" button -- only certain file types under a certain size will attach (but you'll be notified if this is the case).

I would suggest giving Solid Element Operations a try. Search the Help file. It is pretty simple and can be done in Section and 3D views. It's advantage is that you don't need to undo/trim again if a wall moves.

I had noticed a while ago that if an ordinary wall is drawn between
the ends of a "U" shaped polywall then the ordinary wall disappears in 3D.
If the ordinary wall is dragged away slightly from the polywall it appears again.
If there are windows in the ordinary wall they still show in 3D.
Please see attachment. Maybe something like this is what is happening.
