Complex wall intersects in 2d but not 3d

Anonymous — Wed, 22 Oct 2008 14:16:36 GMT

I built a complex profile wall, and it is intersecting with itself in 2d, but not at all in 3d. The reference lines intersect. They were on one side. I moved them to the center of the wall because I thought that might help, but it didn't.
I've built complex profile walls before without this problem. The major difference is the corrugated siding which uses curves and the cavities formed behind it.
Any ideas how to make this work?

and the 2d view:

I can't quite work out what is happening in the 3d view. Can you post a shot preferably showing the top or bottom edges?

I suspect you have another wall with the same layer intersection number hitting that corner either on a hidden layer, or intersecting it above or below.

Also check for any wall reference lines that are offset from their actual geometry that may not be obviously connected.

Just to make sure I moved the walls 1000' off.

This shows the reference lines centered and intersecting.

the 3d intersections fail when the profile is applied, even though the reference lines are intersecting and the 2d plan view of the wall is as expected.

here's a close up of the top

This looks like an issue with priority levels of the different fills in the custom profile.

1) is enable skin priorities checked in the floor plan and section dialog box of the placed walls?
2) make sure the fills for the corrugated metal have a priority number less than the rest of the wall. The priority numbers will tell ArchiCAD what should/shouldn't merge.

That should solve it. I don't think it matters what is/isn't listed as a core component (though that will be important later for dimensioning).

by the way, nice profile!

thanks, If only I could get it to work

-enable skin priorities is checked on all three walls
-I set the channels and corrugated metal to 2 and checked finish component, the sheathing to 4, and the stud to 8 and core component. Horizontal stretch is located at the faces of the stud wall, the opening line is located 1/16 out from the corrugation.

Do you know if it could be the corrugation? I was thinking I've never used curves in a complex profile, but I just remembered I used one to make a table edge once.

I remember seeing this in the AC10 beta. I can't remember exactly but I think it had to do with the origin (thus reference line) somehow. If you can't sort it out you can clean up the 3D with SEOs.

The origin? You mean a project scale/accuracy limit problem? The curves require more precision than is available with current settings? I've seen something like that but it had to do with rendering shadows and was in a different program.

Do you mind posting the profile, so that people here can examine it to see what might be done?

Go into Options > Attribute Manager

Select the profile tab, then select the profile for this wall on the left, click the >> button to copy it to the right panel, then save it as an AAT file. The file it tiny, but aat files cannot be posted here, so zip it and post that.

Anyone here can then import it by clicking the Open button in the right panel of Attribute manager and then appending it onto their profile list.

Alternatively, zip up a module containing just the two walls. The MOD file will contain the profile also.

Thanks,
Karl

The problem went away when I moved the corrugated fill 1/16th off the sheathing?

I also included some wine bottle profiles I made to tests things and although I didn't encounter a similar error, I noticed some problems. If you examine the image you'll notice that on one bottle the cork is broken and you see through the back of the label. The precedences had no effect on this. What did help was to offset the cork and label so they were not touching the bottle. And besides that the glass looks funny. I think it's not controlling the face normals properly?

dmn, it works fine with me on AC12.
Try to make the corrugated layer with the highest priority!

Yes but... In the profile move the metal channels and corrugation so that it is touching the wall element, and this will cause the error?
