There are several options for inserting 3D geometry into your scenes. You can:
• create primitive shapes: cards, cubes, cylinders, and spheres. See Using Built-in Primitive Geometry
• import models and point clouds created in other 3D applications and exported into OBJ (Wavefront), FBX, or Alembic files. See Importing Geometry and Point Clouds from Other Applications
• create your own geometry and point clouds from scratch. See Creating Point Clouds and Geometry from Scratch
Once you've inserted a 3D geometry object into your scene, you can:
• adjust how the object is displayed in the Viewer. See Object Display Properties.
• select entire objects, as well as vertices or faces on objects. See 3D Selection Tools.
• merge objects together. See Merging Objects.
• modify object shapes. See Modifying Object Shapes.
