Wall joins in archicad 17.

[Anonymous]

Im having an issue where my wall joins arent joining on 45 degree angles in 3d like with ac 16. when i try to use custom profiles to make a column, it leaves lines in the sides, it also seems to cause issues with wall coverings. the attachment shows how it looks in 3d in ac 17

turns out this happens when you uncheck legacy connection priorities

[Laszlo Nagy]

With the new Priority Based Connection, one element or element skin always cuts the other element or element skin. This is why they are not joined at 45 degrees.
The Intersection Priority Number of their Building Material will determine which cuts which. The one with the higher Intersection Priority Number cuts the other. If the Intersection Priority Number of the two intersecting element or element skin is exactly the same value, then it will be random which cuts which.
