How do I make a house 3D model faster from 2D plans in SketchUp?
The fastest and most accurate way is Sketchup Pro, which can convert 2D .dwgs into .skp at scale. If that’s not an option, though, you can still do it with vanilla Sketchup:
In Sketchup, draw a flat 2D surface somewhat larger than the out to out dimensions of the house, so that all of the footprint fits in the shape in real units;
Convert your floor plan into an image (.jpg, .png, .tiff, .bmp). Then go to File > Import. Import the image as a texture.
Now, the traced shapes are likely not to scale. Find a known length on the plans and the corresponding line on the 2D shape. You’ll have to scale the drawing correctly by doing some math. Sketchup works with [cool font generator for discord](https://discord-fonts.org/) decimal units, so if you determine that your reference line is 10 units long but it should be 12, then 12/10 = 1.2. So you would select the shapes, type S (scale), then key in 1.2 and hit enter to scale the 1
