In the attached project; 1-I could not make the columns and beams and walls into a single material on the exterior. I couldn't do what is explained in the building information modeling video 2- I want to put the rafters 90 degrees in the y-direction of the irregular roof. I couldn't do it 3-I couldn't find the transparency rate of the balcony glass. I wanted to reduce it. I couldn't. 4-Is there a video of 3d writing on the facade 5-Is there tiles on the floor plan for the presentation: How can I give a laminate flooring pattern? It doesn't work with scanning, thanks, good work, the file is too big, the maximum given size is 4 mib. I couldn't send it, I compressed it, it didn't work again Ali AVCI
