Wall textures not matching

[Liam]

For some reason, I cannot get the exterior walls in my house to match.
Some walls have the correct external siding appearance; others show as drywall.
This is even though the walls are the same type and (as far as I can see) have appearance settings that are exactly the same.
Anyone have any insights?
Many thanks. Liam.

Hi Liam,

Looking at your plan it appears that the two walls that meet the timber post on the corner, do not actually join to each other.  This would mean that they are not viewed as Exterior walls, so do not pick up the Exterior texture.  The exterior surface is only added if 4 walls make up the outer edges of an enclosed space - this this case they are not part of an enclosed space but stick out from it. If you look inside the small room that has the timber post on the corner, you will probably find the siding continues along that wall and the two walls that join to the post are just viewed as 'protrusions' from the exterior wall.

To fix the problem, drag (lengthen) the horizontal wall to the left so that it intersects with the other wall and the texture will continue around the corner. If necessary, move the timber post slightly so that it is still visible from outside.

I have assumed that these walls are supposed to form a 'room' but if these walls are NOT supposed to connect, (ie the corner 'room' is actually not a room) then you can force these walls to be Exterior but ticking the 'Force Surface to be Exterior' box on the wall Properties. Whether it is the right or left surface is determined by the green and red markers at the ends of the wall. Green is where you started to draw the wall, so with your back to the green marker and facing the red one, the wall surface to make exterior, in this case, is the left hand side.

Hope that makes sense and solves the problem.

It would also appear that the walls are at angles and not orthographic or "square" (90 degrees) to each other.

If that was the intent, then all is well.

But you can get straight/ortho walls that intersect at the corners by using snap and ortho "on" (look at bottom right of TFP window)...there are several useful on/off switches located there to make drawing easier....and handy to turn on and off.

Doug. Allan.
Thank you very much for your help.

I am trying to create a porch for the front entrance to the house.
The column in the corner is the roof support for an otherwise open area.

Following Alan's input on walls needing to connect, I extended exterior walls over the porch boundaries and then used cut outs in the walls to define the porch.
This fixed the siding issue in that area. Thanks.

As you can see (attached) the problem persists beyond the porch (going to the garage and the central seam of the house).
The garage wall is on a different location to the porch but seems to have connected OK with the porchway wall, so I don't see why it doesn't pick up the texture as an enclosed space.

Furthermore, along the side of the house, some areas exhibits the same problem. The side of the garage is untextured, however the texture picks up in the middle of the house.

One final thing When I set the cut out heights, any extra height above about 6 feet is added "underground".
The column shows the correct height that the cut outs should be.
It took me a long time to figure out why the cutouts weren't getting taller, whatever the height number I entered into the properties....
Unlike walls where there is a control to specify the bottom height, cut outs don't seem to offer this.
Any advice appreciated.

Liam.

Hi Liam,

The garage wall is on a different location to the porch but seems to have connected OK with the porchway wall, so I don't see why it doesn't pick up the texture as an enclosed space.

The Exterior surface will only continure if there is an unbroken enclosed area. If you have rooms on another Location, while they might overlap each other in the plan they do not connect with each other although in 3D they appear to. The enclosed area still needs to be continuous on each location. This can be achieved by using the Room Divide tool, which is virtually an invisible wall. If you use that to connect the 'open' edges of the rooms on that location, the exterior texture will continue right around.

Remember too that you can force a wall to be Exterior by using the two check boxes on the Wall Properties.

Openings, Windows and Doors heights are all controlled by the Building Location's Head Height. The tops of each of these elements will always be at the Head Height and if you make them taller they will extend down as you have found.  To move individual Doors, Windows or Openings higher or lower than the Head Height, right click it and use the Elevate option.

It is OK to use openings to make the porch but if there is actually no wall there then you can just delete them and extend the roof over the area to the post.
