This section outlines common causes and solutions for slow or heavy performance in IRONCAD.
Causes:
- Opening large-sized files
- Having a large number of duplicated parts with no internal/external links
- Using visual settings that prioritize image quality over performance
- A large number of surface bodies within the data
If any of the above apply, please try the following solutions:
Solution 1: Change Rendering Display Settings
High-level rendering settings can provide realistic part/assembly visuals.
However, during modeling, these settings may degrade performance and affect usability.
If performance issues occur, click [Rendering] in the [Visualization] tab, and set it to Prioritize Performance.
IRONCAD allows you to configure performance settings to maintain operability when working with large files or complex models.
Solution 3: Use Large Assembly Mode
Large Assembly Mode simplifies the display of parts when working with files containing many parts/assemblies, focusing on performance.
You can set the activation threshold for this mode in the Options menu.

Note that certain display and editing limitations apply when using this mode.
Step 4: Use External Links
The external save feature allows you to break large files into separate part/assembly files and display them within the parent file.
To edit parts/assemblies shown as external links, you must open and edit the original file.
Solution 5: Use TriBall Link Copy (Internal)
TriBall offers two duplication options: Copy and Link Copy.
Using Link Copy reduces file size compared to regular copies.
Additionally, editing one instance will update all link-copied instances automatically.
Solution 6: Reduce Surface Smoothness Value
Reducing the Surface Smoothness value may decrease file size and improve performance.
However, lowering the value may result in visible faceting on curved surfaces, so please adjust the value as needed.
