Best practices for increasing performance when working on large assemblies and large assembly drawings in Pro/ENGINEER Wildfire and Creo Parametric
Modified: 11-Dec-2025
Applies To
- Pro/ENGINEER and Creo Elements/Pro Wildfire to Wildfire 5.0
- Creo Parametric 1.0 to 12.4
- Windchill PDMLink 12.0 to 13.1
- Creo+
Description
- Pan, Zoom and Detail entity move operations are extremely slow for large drawings
- How to increase performance when working on large assemblies and large assembly drawings
- Assembly regeneration takes a long time after a simple model change
- Completing a View definition takes long time
- Creating a new drawing from an assembly takes disproportionately long
- Long retrieval time for large assembly drawing
- Very slow while opening or switching windows or sheets to a drawing
- Switching View Display Style from Shading to No Hidden takes long time
- Creo becomes very slow after opening a large drawing file including many (e.g. 13) sheets. It takes a long time to move. Where is this problem mainly caused, is this due to network speed, hard disk speed, memory size? How to optimize the system to increase the speed? Will replacing the computer with more memory completely solve the problem?
- Projection is very slow after cable thickening in Creo Parametric and takes a lot of time to export PDF
- A slightly larger model always has the problem of crashing and freezing of the large model. At present, lightweight is a better solution. Is it possible to use lightweight processing? What lightweight methods does Creo have?
- After the 3D assembly model is adjusted, the automatic update of the 2D engineering drawing is slow (about 20 minutes)
- It is slow to open the assembly model. The model is about 2G and has many features (20-40 minutes to open). After the model is simplified, it is 500MB, and it is still very slow to open, and it takes 20 minutes.
- Slow opening of large assembly component files directly from Windchill PDMLink commonspace
- Creo displays Not Responding when trying to create new drawing from a large assembly
- How to check that Creo is configured properly to maximize hardware resource utilization for large assemblies (i.e. RAM, graphics, cores, etc.)?
- When opening a very large assembly file, for example, containing 30,000-40,000 PRTs, the physical file of the entire assembly is nearly 10Gb, it takes a very long time, more than 3-4 hours. Please provide some suggestions for opening very large assembly files
- Not able to display thick cables in drawing after 4.5 hours of regeneration time
- It needs to regenerate top level assembly file if edit definition parts or open sub-assembly files.
- Slow performance observed when executing tasks in Creo Parametric 11.
- When open an assembly model .asm and modify the model size, Creo responds very slowly. What can I do? (Windows 11, i7-11800H 2.3 Ghz NVIDIA RTX A2000)
