10/5/2023 0 Comments Sweet home 3d background imageI learned that I need to work with uncombined walls to have a correct value for the length of the wall. Wall with connection to another wall, 90° shifted will reduce the value to 875,9 cm. For example: Wall without connection = 888 cm. But if I create a second wall and combine them the value inside the distance field shrinks. When I create a single wall it fits to the size of the background image. I just noticed that this problem occurs when you connect 2 or more walls. Should I trust the imported background or the wall sizes? I can start from scratch drawing new walls but I'm not sure if the plan will be correct afterwards. The background image is smaller than the manually created walls but the settings of the walls shows me correct size of each wall. Then I changed it to 863 / 845 but nothing is changing. Thanks for the answer: I scaled it again to 888 / 863 because the CAD drawing contains the walls. You should try to rescale again your image in GIMP, probably with a factor equal to 863 / 845 = 1.0213 along y.Įmmanuel Puybaret, Sweet Home 3D developer ![]() Re: Scaling issue for the background image, wrong aspect and sizeĪs you noticed, there's only one scale factor and pixels are considered as squares. ![]() So please give me some tips how to do it that every size fits. When I check the y-size I found out that the wall distance of the background image is 845 but it should be 863. The models surrounded with a green border are available in the default catalog of Sweet Home 3D 7.1 free version. I put start point and end point of a wall to the exact size of my CAD plan, e.g. Click on the images of the models to display them in 3D within your browser or click on the link under each image to download the matching 3D model file. It seems that there is a scaling problem or I'm doing something wrong. The 0-point is perfect but the x-size and the y-size of the bitmap are smaller than the drawn walls. I moved the 0-point to x=12 and y=12 because the walls are 24 cm thick. In import dialog I specified the outer wall = full x size of the bitmap and entered 888 cm. Then I resized the picture by ignoring aspect ratio by entering the values of x and y of the house: 888 x 862 pixels. I tried to modify the image in PDF and cropped it exactly outside the walls to avoid any white area around the floor plan. The result of my import was that the background image differs from the walls I draw and specify manually. I'm missing the possibility to specify x and y of the bitmap to perform an automated resize inside Sweet Home 3D to correct the aspect ratio of such bitmap. png using GIMP.ĭuring import dialog there is just one line which can be used to specify the size of a wall inside the bitmap. I want to use it as background image to draw the walls. I've got a CAD plan which was exported to PDF.

I found the availability of types of doors and windows sort of limited. The company that made each furniture item can be seen if you hover your mouse over each individual item. Added vertical and horizontal constraints when shift key is pressed to the scale line displayed in the second step of the background image import wizard. To add doors, windows and stairs, you simply have to go to each respective folder, click and drag, and then drop the item onto the floor plan. ![]() If you want to create a circular room do two semi circles. It took me a few gos at this to get used to it. Another left click when you've got the arc you want to lock it in.Move the mouse around to create the arc you want (still holding CTRL).Make a left click and another left click along the flat wall (still holding CTRL).Imagine the flat wall from where your curved wall extends from.You can make curved walls with Sweethome3D but it's not obvious how.
