found the problem "auto rebuild terrain" must be checked, or user must manually build the terrain. elevation of building is irrelevant. The user doc is silent that this affects driveways, unless one is to know that driveways is "elevation data" Building the Terrain When terrain is generated, Chief Architect gathers all elevation data that has been added to the model and creates a terrain surface. The program interpolates the data to produce smooth contours. A terrain perimeter with no additional elevation data drawn within it generates terrain that is flat at the elevation 0' - 0", or sea level. Select Terrain> Driveway> Straight Driveway, then click and drag a line within the Terrain Perimeter. Multiple driveway sections can be connected together.

I can draw a driveway on the terrain in 3d overview but it does not show up in 3D. I can see it on the plan view. I then created a brand new house with foundation, and i could draw the driveway and see it in 3d. But once I adjusted the building elevations to the ones I had in the other plan (top of main floor is at 33") , and set the terrain to manual, I cant see a new driveway once I draw a new one in 3d (although I can see the original). I then moved the main floor back to 0" and then drew a new driveway in 3d, but I cannot see that one either, only the original Anyone seen this issue? you can see the many times i tried below. but the 3d only shows the original. if i look "under" the terrain, it is not there either. demo plan attached driveway.plan

well some more information. it only frames like if i have it as "Boxed" and only until I put the top of window at 93.25. 93.25+3+3+9.25+0.5(R0)=109, which is what my wall height is. once I set to 93.5, CA removes the top and bottom members from the header. So I suppose that is consistent for a boxed header, just not what i want. ...wait for X13 maybe. but for those that are not 2x10, i should change the window default to boxed, as then at least they will show correctly

thanks, found mine by dong this

well, you picked up on it I think. The reason it shows as it did in mine is there was insufficent space. 109" wall, 96 to top of window. 96+1/2+9.25+3+1.5=110.5. 1.5" too tall. but in testing this, it still does not show up at 94.5 and instead puts in cripples. BUT if Iower the window even more if does show up.(see sceenshots below) Bizzare? This explains why I saw this same "missing member" in some of the videos @genedavis: so are you having to add in this horiziontal member for every plan that there is a 2x10 header (or other size as the 2x6 on the window below shows no member) and the window heights match the door height?

"Check out the video starting at 4:40 https://www.chiefarchitect.com/videos/watch/10231/wall-framing-what-s-coming-next.html?playlist=171" looks like they have added it by giving the ability to specify "top of wall" for the header location On a side note, some framers here will frame the header at the top of tall walls as well. helps with insulation as the header is effectively in the attic Thanks for providing the video

so if I lower the roof, I can get the wall to 60", but I cannot get the heel of the truss to be tall enoguh then. It looks like the software does some sort of math, that if the roof is x inches higher than the wall it builds another wall on top of the wall. but if it is more than x+y it does not. For instance if I change my roof baseline height to 280, the wall build to 60", but the truss heel is only about 13", If I change to 290, no wall change and the truss height is 23". When I change the roof height to 283, i get the goofy wall on wall again with the truss drawn through it this is totally repeatable behaviour. I did some more testing. the "top up" wall starts when I increase the roof baseline to 281 and stops when I increase the roof baseline past 289. In summary, if the roof baseline is greater than 280 or less than 290, I get the top up wall effect. This means I can only get a truss heel height of 13" or less, or 23" or higher, without having a top up wall being auto built(and my truss being shown as through the top up wall) Bizarre

Been working on this for two weeks now, Even recreated my plan as a simple box. and followed the instructions. had to deviate on the ceiling plane because it was creating a gable wall instead of a tall wall. the ceiling plane extends to the outside of the gable wall. The tall wall is now drawing correctly I need essentially a siccor truss with a different height at the top than height at the wall. I tried using an energy heel without much luck so I went with specifying the roof plane higher than the ceiling plane and specifying two different pitches The problem is the end walls keep drawing higher than I have stipulated in the room specification under "structure". I have rough ceiling hight as 60: and ceiling ( as 266 1/2"(as this is the third floor). but the section keeps showing a higher wall. when I play with the ceiling plane baseline it just lowers the truss and it builds it into the wall. I tried rebuilding the wall And my one wall has another wall auto built on top of it. Its like its trying to build a wall to part way to the roof. Its not all the way Does someone have a simple plan with a parallel chord type of setup and where the room structure absolute ceiling height(I assume this is the top plate) matches the section drawing? I'm trying to use a siccor truss and I have the ceiling plane ay 6 5/8 pitch and roof at 7". Cieling plane outside bottom height is 270 1/2. Roof baseline is 282. So I'm expecting either a 12" truss or 12" plus perhaps the depth or something. And it does look like it builds the proper height of the truss. only problem is the wall. It's being drawn 13" too tall. I tried lower my celing but the trusses just get built through the wall. at my wits end
