Plaster, horizontal lath - Yes, house was built in the 30's and originally is plaster and lath. Since one of the most common wall types on the planet are left out of this program and I really could not get a suitable material made for lath, the scratch coat includes the thickness of the lath. There is no brown coat since the scratch is a gypsum/concrete mix with plaster over it. I do not believe the scratch has any lime in it. The thickness of  It has had a few renovations where they added drywall over the plaster in several rooms, paneling over plaster and where the plaster and lath were removed and drywall was put back. So each wall type has to be defined several times with the fixed interior/exterior motif in order to get the proper material on the interior of a room.

DJP-

Automation is the frustrating part of this software. They just seem to leave simple key aspects of control out. I used AutoCAD throughout most of the 90's and you would just define a wall as exterior or interior and then automation would take over or you could override automation. I was wondering if the material definition was causing the issue since CA seems to put a scratch more in exterior finishes associated with stucco. I am dumbfounded that I have to build one of the most common material sequences in housing and that plaster and lath are not just a part of the materials selection of a wall. To be redundant, there are just simple, basic fundamentals that this program lacks and it shouldn't.

Here, I built the outside perimeter and started adding interior walls. I did not think you could name a room (ygmn response) until you defined the space either by enclosing walls or using a room divider, which is done here.

Back to DJP, I am concerned on what automation is going to do since this is a support wall. Normally, I would not care, except for the way CA aligns the walls. I have a second floor, basement, and crawl space. So it is my understanding that the wall thickness needs to be relatively precise since CA aligns each wall level off of the center of the wall and I have a wide variety of wall thickness that can add up to a couple of inches variance. My house is a 1930's budget, midwestern, gothic farmhouse, originally shaped like a T, with a porch added to the front (now a cross shape). The framing is balloon and this wall stops at the second floor (support 2nd floor) and goes down to the basement foundation. I do not know the impact of CA thinking this is an exterior vs interior wall. I've already had to deal with CA popping an exterior vertical triangle wall segment on top of this wall (turned off roof for this wall). I thought it odd that I can delete the wall segment, use just a default straight interior wall tool and it still calls it an exterior wall. I get handles in the correct location for an independent wall segment. For now, I will just ignore msg.

I have a half dozen wall types in my house so I am creating each one. I was updating the interior/exterior series on a wall type and got the following error msg. This is an interior wall. Help says no help on this topic. I deleted the wall, created a new one sans door and opening as an interior wall, applied my wall type defn and got the same error msg. I'm confused. Does CAP think this is an exterior wall. How do you change the wall type, delete and draw a new wall?

Represent how? Well as lath, instead of making something up to account for the thickness. I guess I don't understand the thrust of the clarification request. Lath in my house is typically 3/8" x 1" x 36" or 54" slats space horizontally roughly 1/2' apart. In either regard, I have a house built in 1936 that has plaster and lath on the walls and ceilings. The walls are roughly 3/8" lath, 1/2" scratch coat and 1/32" finish plaster. I have some remodeled areas that are lath and drywall, some that are just drywall and some that lath, plaster and drywall. I would have thought there would be an editable material choice for lath along with the balloon framing since drywall was not around during the main period of this framing type. Some parts of the country, the lath is 2-3" by 1/2" thick. Depending on the period of construction, they can be 36"/54" for 18" on center studs or 48" for 16"/24" on center studs. I upgraded to handle balloon framing and plaster lath wall systems are an integral part of this construction method. Having balloon framing with no lath material is kind of like having a car body with no frame. That 3/4" thickness adds up when you are trying to get the walls aligned on interior dimensions. So it would be nice to have the proper representation. I'm not sure of the possible views with framing and wall construction. If you can see the layers, it would be nice to see the base as lath.

Are we talking wood-strip lath, as in days of yore?  Yes. Interesting idea. Seemed odd until I read the help on how to use. I'll have to give it a whirl.

So at this point the answer seems to be no there is no plaster and lath material or wall type and one must employ some gimmick to represent or draw in the lath as part of a wall definition.

Is there a Plaster and Lath wall type? I can simulate this construction but it leaves out the lath. There is wire lath, of all things odd. I've found scratch coat and the plaster finish coat, but would still like to represent the lath. This is a fairly basic and common wall type in the US.
