#1095 Two mysterious triangles appear in my model

[Chuck Berg]

As shown in the attached screen shot, highlighted in red, there are two triangles that appear in my model that do not belong. But I can't find out where they are coming from and therefore can't delete them.

How do I get rid of them?

These are some parts of the ceiling which are not computed correctly. It's quite strange because this kind of issue generally happens when a corner of room is at the end of lower wall, but it doesn't seem to be your case.
I would suggest to hide the ceiling of the large room in its modification dialog box, or maybe create smaller rooms.
Note also that the coming version will have also a Ceiling always flat option that will also avoid this issue ;-)

Bonjour,

Pour information, je reproduis le même problème que Chuck, en créant des murs de petite hauteur dans une pièce (1 cm, 50 cm, ....)
Je confirme que le masquage du plafond supprime le bogue.
Merci pour ce post qui m'a permis de m'en sortir.

Bien à vous.

Damien.

Sweet Home 3D 7.0 brought the new option Flat ceiling only in room modification dialog box.
This option is selected by default for new rooms but selecting on existing rooms in your project should fix your issue.
