Ah... I found out what I did. I had changed the material for the 8" foundation wall to drywall (for the look of it) not realizing CA needs to know it's made of concrete to trigger it to create a sill plate. Interesting.

Not sure what is happening, but the sill plate doesn't show up on the BC cross section. I am pretty sure I checked all the boxes correctly... any idea? Thanks!

@Kbird1Got it. Save directly and don't make into a symbol. Thank you!

@Kbird1Interesting for sure... but does that mean I can or cannot turn the symbol back into a 3D solid... or, and, are you suggesting this Layer the symbol is stored on can somehow affect it's look in section view... and that its state can be changed to make the view better?

@Kbird1 yes, I made these objects into symbols. Does CA treat symbols differently than 3D solids? I guess so... and wonder why. Can I turn the symbol back into a 3D object then? @DBCooper I did this experiment from a new plan with no other objects but those, just to see. @MPDesign It does seem to work if you extend the view past the objects... but then, when I have it included in the rest of the plan I don't want to extend the view in order to make other things work out....

Not sure why this is happening, but when I place a 3D object on the plan and Back Clip a cross section I get only partially constructed lines showing in the section view. Any ideas?

I am wondering if CA(x15) has a more automatic way to create a notch in the stairway wall similar to this: (see red line for shape) Thanks! (Also wondering if there is a way to change the width of the stringers when choosing the 2 end stringers option?)

@Renerabbitt True. I did want it to align with the sheathing layer. I think I found a work-around (at least until I can discover a better way) If I leave 'outer surface' checked (as @DBCooper has suggested) and create an additional outer layer at thick as the main outer layer, and call it an air gap, and check it off as so, then things line up with the sheathing.

I'm sure there must be an easy answer to this but it escapes me. When I create a simple pony wall with Siding-6 upper and 8" conc lower it produces this: But I am wanting the face of the concrete to be flush with the face of the sheathing layer. I think I tried all the settings I could see but nothing seems to affect the relationship between the upper and lower walls.

@GeneDavis I think I have it. I did go back to an original template, unmodified, as you suggested, and tried again. This time it mostly worked. I realized I needed to check the box for 'air gap' for the air gap layer to keep the little vertical line to the left from going up past the top of the foundation, and to only set the stud wall as a framing wall. I left it the wall with 2 top plates. When I build the foundation with the combination concrete and furring wall it works well if the ceiling sheetrock is not present. Once I turn on the basement ceiling sheetrock the top plates stay up against the bottom of the floor trusses correctly but the sheetrock line goes behind the studs and reshows itself in the air gap, stopping at the concrete foundation. Interesting. Maybe it was the way I cutting the cross section. What I did then was to not have the foundation wall definition include any furring wall, but instead just created a definition for furring wall only. (the video also showed that as well). When I place the furring wall up against the foundation and build the framing it all looks proper, even with the ceiling sheetrock, so I think that's a good answer, and more flexible. Thanks again for the suggestion to make a fresh start.

@GeneDavis Thanks for helping on this. Here's what it shows:

I have been following the video titled "Creating Basements with Furring Walls and when I get to the point where he shows a cross section it looks like this: But when I follow the same pattern he is using (CA 15) I get this: For some reason my furring wall does not go all the way up to the underside of the floor trusses, but stops at the ceiling sheetrock. I'm using a wall definition that includes the furring wall as part of the wall. Any ideas? Thanks!

@GeneDavis Thank you. I had not realized that the framing check box was independent for each material. I take your point well on watching videos, and have have a whole list of them favorited. Hopefully they will all mesh together as time goes by.

@GeneDavis That makes sense.... but I'm not sure where to find the dialog to change those settings?

I am seeing that when I build framing the floor trusses show a multiple top chord layers. I'm not sure what's happening here?

I am a bit new to CA (x15) and am finding that I seem pretty comfortable with most aspects of the program except cross sections. Coming from 2D drafting I can make the cross sections look exactly like the way they are constructed, along with the best way to delineate that for clarity (at 1/4 scale). After creating a plan in CA, when I cut a cross section (back clipped) I am finding CA does not show intersections of floors and walls and roofs that well. At least as far as I can figure at this time in my learning. I am wondering what steps any of you use to get the most accurate looking cross sections so that it doesn't require much extra enlarged details and manual cleanup and the like. Do I need to build framing? Use the Add extra detail button? Be more careful about which layers show and don't show? Or....? Thanks!

@Gawdzira Do you (or anyone) have an idea for concrete poured stoops+steps so it looks in section like the way they pour it?

I am new to CA(x15) and coming from 2D CAD. I am wanting to make a concrete front stoop with steps that shows up properly when the back clipped cross section is created. I haven't found a way to make it look like the way it is actually poured. I tried making it out of 3D objects and saving as symbols but then stretching symbols to get them to the right size causes deformities, and even still I don't see the lines properly in the BCsection method, though it does look okay with the elevation cross section (but I'd like to not have all that color for the final print out). How is this best done so it shows well in sections and looks like the way it's poured? Thanks!

@para-CAD I would do as you suggest... make the truss shallow and fur down, but then the exterior plate heights have to go up and vary room to room and the carpenters like it when all the plates are the same height so it's easier for them in the field.

@ValleyGuyThat's an excellent solution. Thank you! I sure wish CA would incorporate a tray ceiling option into a floor truss. That way the cross sections would be more accurate to the way residential builders actually build here.

I'd like to create a flat roof truss with 0 degree slope, but CAx15 automatically seems to force 1/4"per12" slope. Is there a way to override this and make it no slope? On our low slope roofs we use either tapered rigid insulation or sloped sleepers as it's easier for the field guys to shape the slope without being limited by the trusses.

Can you fellas think of any creative way to get a tray ceiling into a floor truss? I do this all the time with great rooms. (now where's the cross my fingers emoji?)

Can CAx15 allow somehow for a raised, or boxed up ceiling into a floor truss? I have tried buy the error message said it wasn't allowed. We get the truss manufacturer to make them this way for our homes.

@robdyck Got it. Thanks!

Joey; I think I am reading your mind I am wondering if I reset the order of the materials and put the main layer only as fir framing, then it gives me the option to pick 1,2 or 3. I will try that. Thanks!
