Re: How do you prevent one wall from bleeding into another wall
Thanks for the replies. I didn't even realize I had replies - I didn't receive any notifications.

When you move the 3D view, do the white parts shimmer a little with red through it? If yes than that is proof that there are two walls in the same place. If you already have walls without your red wall than use the existing walls to paint the outside red, don't add an extra wall,


No, I don't notice any shimmering.

The reason I want to add a 'wall' representing siding is so I can quickly change colours of the siding. There are a lot of colour combinations to go through. Especially if I add trim and drainage. If I do it the way you suggest, it will take forever. I only showed you one small section of the house. To have to change colours of multiple items in every section, an unknown number of times, would take forever and be incredibly tedious. There are so many walls to sort through, and windows, and frames, chimneys, etc, finding the item I need to click on can be complicated. I drew those existing walls when I had just installed SH3D for the first time and didn't know what I was doing or what problems I might inadvertently be creating for the future. The way I'm reading your response, it sounds like I might have created a problem by drawing everything wrong. I was just trying to construct a model by entering the measurements I had taken, one by one, by hand, in what seemed like the most logical way. I would do it the same way if constructing a new model because it still seems like the most logical way to gather and enter the data, and I'm continuing to gather and enter data that way when I add something to the model. IDK what other way you could measure things and have it turn out looking remarkably accurate, like my model does... But apparently this means you can't really add a 'wall' to represent siding after you're finished measuring and painstakingly entering all your measurements.

The existence of this problem makes no sense to me. In the 2D screen, I am looking at walls that do not extend into the area occupied by the siding 'wall'. But the 3D model says the opposite. The X-axis & Y-axis coordinates in 'Modify Wall' look accurate.

Your wall is 950 high so it covers multiple levels. In itself no problem but you should consider doing it the right way and keep wall heights to the level.


I agree with Keet. On all points. When starting out, always best to keep walls to the level height or you will get confused later.


What's 'level height'? I measured everything, the walls, to their exact dimensions, and entered them as walls. In most cases there's a floor above them, and then another wall, entered separately. Any wall on a floor higher than the one below, obviously has to start at a higher height - that being above the flooring, which has a thickness, and that flooring is above the wall below, which is how I entered them - is that the wrong way to do this? If a wall is 250cm high, and the ceiling/floor above it is 15cm thick, then the wall above that has to start at 265cm and go to a height of 515cm - and so on. You end up needing the sum of those walls and the extra space such as flooring and ceiling space to cover the exterior of the building. The 950cm was just an estimate I entered to test out my 'siding' wall, but I don't need it to be quite that high. I was thinking "what's the total height of the structure without looking it up" and estimated 950. But I forgot about the basement, which alters how much siding is needed. If the siding wall was working the way I expected it to, I would then edit the height of the siding wall to match the actual above-ground height of the structure.

I do have levels. 3rd floor is on a separate level above 2nd floor which is on a separate level above Main floor which is on a separate level above Basement. The starting heights of the walls reflect which level they're on.

So I made the siding 'wall' 950cm high so it covers that entire section of the house, like siding would IRL. What am I supposed to be doing instead? Drawing separate siding walls for each section of wall I measured and entered? That would defeat the purpose.
