So you've got an OBJ file and you want to bring it into AutoCAD for some 3D magic? No problem, I've got you covered with a quick and easy tutorial. First, open up AutoCAD and navigate to the 'Insert' tab. From there, select 'Import' and then choose 'OBJ' from the file types. Once you've located your OBJ file, click 'OK' to begin the import process. AutoCAD will then prompt you to specify the insertion point, scale, and rotation for the OBJ file. Once you've made your selections, click 'OK' and watch as your OBJ file is seamlessly imported into your AutoCAD workspace. Now you can use all of AutoCAD's powerful 3D tools to further manipulate and design with your OBJ model. And there you have it, importing OBJ files into AutoCAD is as easy as that! Happy designing!
