Performance of Simulation

General Questions
1

Hi all, not sure if this is the correct category…

If have a question about Simulation performance.

If i have a simulation running ( little bigger layout), it performes ok.

Than during the run, i make a STEP File visible, which is more or less the Template for the Simulation, means the Layout of the “real” system.

As soon as the Layout is visible, not in the view of the screen, the simulation starts to get extremely slow. After making it unvisible again, it performs as before.

Does anybody of you know the reason for?

Is the size of the STEP file placed large?

If so, it may need to be resolved through layout optimization data.

it is about 80mb, quiet detailed, yes.

I only wonder that this “static” layout has that much influence on the performence…

I’m not sure, but I understand that large STEP files can cause layout degradation. Search the academy for optimization and apply it to the layout.

My guess is that the large geometry may get included in things like raycasting and collision checks when visible. If it is just a single geometry set then worst case scenario is that every triangle in it gets iterated through in some operations because the bounding box spans the whole layout anyway.

Could be just rendering too even if it is not in the camera viewport, does the viewport frame rate drop when you have it set to visible?

yes, as soon as i make it visible it goes down. Generally no problem, because i do not need it for simulation. But would be nicht for making some Videos for the Presentations. I will try to optimize the layout and give some more feedback.
