different wall type intersections

Anonymous — Tue, 09 May 2023 13:48:51 GMT

Hello again from a beginner,

As shown in the attached pictures, the first one is the intersection of two walls of the same material which goes smooth, in contrast to the second picture where the intersection reaches the insulation.
I have tried in vain, to switch the reference line, but the same happens.
Is it possible to have a smooth intersection (like the wallf of the first picture) between the walls of different materials?

thank you

Check the building material priority.
Looks like the other wall has it's priority set too high.

Yes, each building material has a strength.
The stronger ones will cut the through the weaker ones.

You can adjust the building material strengths or you can adjust your wall composites so they use building materials with the correct strengths to achieve the joins you want.

Sometimes this may require duplicating a building material and giving them different strengths.
Then creating 2 wall composites - so each wall can effectively have different strengths.
You can then choose to use the stronger or weaker wall, depending on how you want them to join.

If the same building material is used in the walls, they blend as in your first image.

Thank you very much, it had to do with priorities but i did it as ashown in the first picture.

In the second picture there is an intersection between two composite walls with insulation, and a brick wall. Is there a way to avoid this little gap as shown in the second picture?

Thank you,

In the second image, is the insulation modelled as a separate wall? If it is, just put it on a separate layer with a different Intersection Group.

Either way, is the Intersection Priority of the brick Building Material stronger than that of the insulation? Where are your reference lines?

It looks like you have a situation where 3 walls are trying to join with each other.
Only 2 can trim properly.

The 2 external walls with the cladding should be the ones trimming.
Each wall has a 'Junction Order' in its settings (or info box).

Try making the horizontal internal wall have a lower junction order than the others.
That should force the two external walls to trim.

Or if that doesn't work you can try to reposition the wall reference lines.

Also what version of Archicad are you using?
To me it looks like a version 15 or older or you have the 'Legacy' option turned on to make it behave like an old version.
It looks to me as if the walls are mitring at the corner - which they only did in old versions.
They should overlap based on building material strengths of each composite skin.
