Once the object is loaded it should appear in the view screen. Warning! it make take some time to load if the model is large (you may consider decimating the model in the program used to create it or by using Blender itself). Select the following from the menu: File→Import→Wavefront (.obj). The next step is to import the 3D model (this tutorial uses OBJ, but is similar for other file types). Then, with the mouse inside the 3D View window (keyboard shortcuts only work if the mouse is hovering in the right area), press X or the delete key. Right click on the cube and it will be outlined in orange. This is done by first selecting the object. If you have the default setup for Blender, then the first step is to remove the default cube. This tutorial is designed for the Blender beginner, but I generally will only cover Blender basics related to this process. Blender has a large community and many free tutorials if you would like to become more familiar with the basics or expand your knowledge. The software can be used to create an animated movie from scratch orĭesign a 3D game, but it can be overwhelming at first. I’ve chosen Blender as it is free and comes with no restrictions. Whatever the reason you need a 3D object scaled to the right size, this tutorial will show you a simple method using Blender. Many laser scanners or structured-light scanners automatically scale the object, but often models created using photogrammetry lack a true scale. Once you become familiar with this process it will only take a couple minutes to complete.ģD models are great for measurements that are difficult to obtain from physical objects, but first the 3D model itself must be the right size.
You will need a 3D model in a common file format (I use OBJs) and the measurement of the longest axis of the object.
