What is Pro/E’s default precision? What is the default precision of UG?

Depending on the particular version and setup, the default tolerance or precision settings in computer-aided design (CAD) software such as Siemens NX (previously known as Unigraphics or UG) and Pro/ENGINEER (now known as Creo Parametric) can change. However, I can provide you with some general information:

1. Pro/ENGINEER (Creo Parametric):
– Pro/ENGINEER typically uses a default precision of three decimal places or 0.001 units. This precision level is commonly used for most design and modeling operations. However, users have the flexibility to adjust the precision settings based on their specific project requirements.

2. Siemens NX (Unigraphics/UG):
– Siemens NX also allows users to define their own precision settings. By default, NX typically uses a precision of four decimal places or 0.0001 units. This level of precision is suitable for most modeling and design operations. However, similar to Pro/ENGINEER, users have the option to customize the precision settings as needed.

Both Pro/ENGINEER (Creo Parametric) and Siemens NX (Unigraphics/UG) offer extensive customization options, allowing users to define their preferred precision settings to match their specific design and manufacturing requirements. It’s important to note that precision settings can have an impact on file sizes, computational resources, and overall performance, so it’s crucial to strike a balance between precision and practicality for each project.
