2 composite Walls and Slab intersection

Anonymous — Fri, 19 May 2023 20:34:20 GMT

Hi Guys!
Doing some interior construction I faced an issue with the intersection of three elements: ~~[list=]~~

SLAB (composite)

~~[list=]~~

WALL1 (composite)

~~[list=]~~

WALL2 (composite)

The problem is shown on the picture above in the red ellipse: Plaster from the WALL1 should go further to the WALL2, but it is not happened because intersection priority of Concrete is more then of Plaster.
Intersection priorities of the building materials in this case is the following: ~~[list=]~~

Concrete - 900

~~[list=]~~

Gypsum Concrete - 600

~~[list=]~~

Screed - 500

~~[list=]~~

Plaster - 210

If you make intersection priority of the Plaster more than of the Concrete, Plaster from the WALL1 will go further to the WALL2, but another problem will appear between intersection of the WALL1 (Plaster skin) and the SLAB (Screed skin):

In this case Plaster goes to the Screed that should not be.
Intersection priorities of the building materials in this case is the following: ~~[list=]~~

Concrete - 900

~~[list=]~~

Gypsum Concrete - 600

~~[list=]~~

Screed - 500

~~[list=]~~

Plaster - 950

Is there any way to solve this problem? In the end Plaster from the WALL1 should go further to the WALL2 and souldn'g to the Screed of the SLAB.
Thank you!

Just create another plaster material with a higher priority than concrete, and assign each plaster to each composite depending on what you want...

Does swapping your reference line to the opposite edge help?

It doesn't work.

Actually it doesn't work.
If you set intersection priority of the Plaster is more than of the Concrete, intersection priority of the Plaster will be automatically more than of the Screed and the Plaster will penetrate to the Screed which is not correct:

If you try to solve it and set intersection priority of the Screed more than of the Plaster than Screed will penetrate to the Gypsum Concrete which is not correct also:

If you try to solve this either and set intersection priority of the Gypsum Concrete more than of the Screed than Gypsum Concrete will penetrate to the Concrete (which is not correct either) because eventually intersection priority of the Gypsum Concrete will be more than of the Concrete:

So this is like vicious circle. Don't know what to do(

Is there any issue with creating a second Concrete for your wall with the same Intersection Priority as the gypsum Concrete? In that way they will join to each other and the intersection can be controlled with the Junction Order.

OMG it works! You're a god of Archicad! Thank you!
