Geometry errors come in two types:

1. Visual
2. Hidden

Visual Errors
Can be detected in previews:

• Non-compliance with specifications
• Holes in geometry
• Coplanars (intersecting planes)
• Logical errors (tree in a wall, a submerged car or driving the wrong way, etc.)

Hidden Errors
Can be checked by opening the scene. They affect performance, comfort, and work speed:

• Scene organization (layers, rational use of Xrefs and proxies, absence of groups, naming, ID, system units, etc.)
• "Junk" (excessive) geometry

Achieving clean geometry is only realistic with experienced modelers who understand your regulations.

Modeling and geometry optimization is an integral part of every project. Over my time working in 3D, I can make two main conclusions:

1. There are mistakes and shortcuts in any! scene
2. The fewer errors in your scenes, the larger volumes of work you can handle.
