Corner Wall intersection.

Anonymous

Hi guys, traditionally when faced with an intersection like this I have applied a small fill over top... Can anyone recommend an improved way of dealing with this corner join?

(Picture shows an internal wall joining a cavity wall on the corner).

Im thinking perhaps the wallend tool might be usefull in a case like this?

Two jobs, one for a Construction company where I use Autodesk Land Development and Revit 6.1 and I work part-time for an Architect using Archicad 8.1.... So I get to see what both 3D programs can/can't do....

There is no need to patch for the intersection to clean up.
Just put the reference line of the walls as shown by the arrows in the attached picture.
I have never encountered any problems this way. Just remember the reference lines have to connect.

You're absolutely right. However the main problem I have with this solution is, what happens at the other ends of the walls? You change the reference lines here and at the other end of the wall there's another wall made up of other components and that intersection doesn't clean up.

And you're sure turning the wall end off won't solve all your problems right?

Turning off the wall ends does nothing (try it ). How the reference lines come together is everything. In the attached picture the reference lines of walls A and B come together. The remaining wall hits wall A but has no contact with B. Instance 2. shows how the reference lines come together. Instance 3 shows how they clean up (wall ends are set to show).

So these walls will clean up if you get the reference lines right. My point is that you can spend a lot of time trying to get this intersection to look right. If you spend 10 seconds on it and you can't get it right ... use the patch and move on! It has absolutely no effect on the model.

Wall end visibility works a lot of the time. That's why it's there right? And conscientious reference line placement is also key to have walls heal properly (unfortunately) along with deft use of the adjust command and appropriate layer intersection priority numbering.

The patch is a hard sell IMO, simply because it is not live. But that's just me!

Best regards,

Not going to argue with you on that. But at the end of the day, the drawings go out the door. I think people need to look at patch tool differently. In my solution to the problem, even if walls A and B are the same material an elevation won't clean up properly. The same is true if the wall ends are turned off. With Hielke's solution they will but there may be other consequences. How much time does one spend on it?

The patch, by the way, is also great in the section or detail windows (see attached). It's scalable too, so you can use the same patch in the section at one scale and in a detail at another scale

It's already there.
In the TOOLS menu > MODIFY WALL > REFERENCE LINE

As far as I can tell, it doesnt just move the reference line, it flips the whole wall... which is about as usefull as uhm.... something not very usefull...

I want the reference line to be on the other side of the wall, not have the wall flipped around...

Basically, You will find that if you re-create the image above using an UPSIDE DOWN composite, that corner will work perfectly... so basically when I want to flip the reference line, I want it to convert the wall into an upside down composite...

I think this tiny little feature would be really easy to implement into the next release of AC, and would save people hours of work...

Ofcourse you simply cannot work with upside down composites because it is hard to trace around things when the wall is upside down.. (just try it if you dont believe me).

Let me know if Im not making sense...

You're not making sense.

The Modify Wall command does exactly what you describe - no flipping, no flopping. That's why it exists. Otherwise we would be stuck with the reference line options in the info box & wall tool dialogs.

Mine just seems to flip it...

Showing before and after, note I have the left wall selected, I click on EDIT, then MODIFY WALL, then REFERENCE SIDE, then Change to RIGHT..

it has completely "flipped" the entire wall, not just the reference line...
