why "Recompute walls" is disabled?

[qinshaolin]

why "Modify rooms"dialog box, "Wall sides around room"->"Recompute walls"check box is disable,how enable "Recompute walls"check box?

[Puybaret]

This check box is disabled when there's no wall to recompute anymore.
But that doesn't mean that you can't change the color or texture of wall sides.

How to make it effective,enabled the checkbox?

[okh]

If I understand this correctly:
Changing the wall colour/texture from the room properties works on walls connected to the room. But as one wall can be connected to several rooms, the "Recompute walls" box will split the walls, so you do not apply the colour/texture on the part of the wall that extends outside the room.

So, it there is no "Recompute walls" box, there is no need to split (recompute) walls. And therefore no need to enable it as it would do nothing anyway.

But maybe you have also moved your room or a wall slightly, so the room doesn't touch all walls. In which case you can delete the room, and then use the Room tool and double-click inside the room to make the room fit exactly.

Hope this helps.

ok

now one wall connected to two rooms,apply the texture in one room,but wall's texture extends outside another room,need to split(recompute) the wall,how to make it?

[okh]

Make sure that there are no openings in the walls of the room, delete the room, and then use the Room-tool (Create room ) and double-click. You now should have a room that fits the walls exactly - and the option of recalculating the room should be available if one wall extends outside the room.

It is also possible to split the wall manually. Select the wall, use Plan>Split wall, and drag the new wall connection to where you want it.

Good luck.
ok
