Performance issues with assembly

b.garrell — Thu, 29 Sep 2022 08:04:56 GMT

Hi everyone,

We have been experiencing bad performance from fusion 360.

Recently we are working with a model made out of STEP files and has been a real headache.

First we had problems managing and assembling the model, we updated our hardware with +32GB RAM memory, modeling 3D was then solved, but this is still not enough to draw the model in 2D. It is completely impossible to set the first model projection in the 2D sheet, the image blurs and the aplication freezes.

We really do not know what is the problem as the computer never uses more than 40% of its RAM, CPU usage stays around 18% and GPU at barely 2% (has 2GB dedicated). Tried to simplify the model by hidding assemblies with many parts, but still got no result. Even tried to reduce the graphics quality thoriugh Fusion & NVIDIA applications but no result was obtianed.

We have recently tried other softwares such as solid edge and we had no problems drawing and managing around the model.

Does anybody can give some insights in how to work with models with several assemblies?

Hi,

Share an appropriate sample file with hints on what should be represented in the drawing.

File > export > save as f3d on local drive > attach it to the next post.

I am sorry but can not attach the file as it is is private intellectual property from our company.

This project will be released in the near future.

I know it would accelerate a solution but it is not an option.

Apologies for the inconvinience, I will do what I can with general tips.

I was talking about a sample file, not the actual project.

Find attached a 10 ft container step file and its 2d drawings.

That is what I am trying to do with my real project.

I can modelate the 3D model but Fusion 360 crashes every time i try to put the first view in the 2D sheet and closes.

Is that the "sample" you are asking for? I am not really understanding your request.

Regards

Hi,

What I see:
Realtime screencast

(view in My Videos)

However, display errors in the projections cannot be overlooked.

What display errors?

I also had no problems creating 2D views in a drawing. Not exactly super speedy, but workable.

1. Visible edges display 00:54 to 01:20

2. In this screencast it becomes clearer

In first video I see clearer what is happening in my model.

As you can see between 00:36 - 00:38 Fusion black outs in the right part of the screen.

I am having this problem permanently and the application stops working.

The model I am using is way bigger than this one, has several assemblies inside.

No idea if this is a Fusion problem or my PC can't perform any better.

Hi,

From my point of view, there are two problem areas:
1. the creation of drawings of too large a number of assemblies.
Tip: The construction should be organized in assemblies and subassemblies in such a way that when creating drawings, only the ones that are to be displayed are activated.
2. the representation of parts in the drawing ( screencast # 😎

The blackouts happen every now and then.

I believe this is an area where Fusion 360 is not very performant. While I work in a number of CAD systems, I usually don't create manufacturing drawings of large assemblies. As such I don't have anything to compare drawing creation with in terms of performance.

I have an assembly with over 6000 components (concept model for manufacturing automation) that I started before writing this post. It's not done yet and I sit on a fairly quick computer wit AMD 5950X.

Just now I was able to place the initial view and it is not bust to create the actual view on the drawing.

Can you do a component count of your assembly?

Open the text window and type component.count into the command line.

Edit: It took about 5 minutes from the start to creating the 1st view on the drawing.
