Fusion 360 takes too long to compute changes

[hateyaall]

Hello, people

I have this issue that i can't work through. I am drawing a honeycomb for 3D printing. It will basically take the full build plate of an Ultimaker S5. In Fusion the drawing of that honeycomb is a terrible experience. The changes i make on my parametric design take too long to be computed by Fusion. I have combined them to become a single body. Also I am working with parts of the honeycomb that after I am done modelling i combine together. The process is very slow since i wait between 2 and 10 minutes for any single change. And some changes crash the whole program. Is there a way to make my design lighter for Fusion to handle or any other way to speed up my work?

Hi,

Did you pattern the sketch or a feature (extrusion).
If you have patterned the sketch, it may look like this, especially if you have many elements.
Note: Sketch only one instance. This will then be extruded and finally patterned.

I did a sketch of only a single cell that is of course slanted at an angle. I have two sketches to loft between them and make the angled cell and then pattern the body. After pattering the body i combine all bodies and have like a section of the honeycomb. Then move on to the next section(part). After that i join them all together and combine. After combining all the sections changes become impossible. Before combining changes can be done but i have to wait a lot.

Hi,

please share the file

what options did you use in the pattern?  Use "Face" pattern, or "Feature", with type set to "Optimized".  If you use "Feature" of type "Adjust", that will be super slow.  But, again, share the design if you want more assistance.

OK this is it don't mind the bottom thing that is not complete and the cells are filled out.

Hi,

In this case, a different procedure is recommended.

Therefore, I did not try to change anything in the existing file.
Take a look at the screencast and file and implement the concept if you like it.

Hi,

sorry about "double post" , edit post does not work for me.

Wow, you teach me something Günther 👍
This is the kind of advanced strategy I'd like to see more often on livestreams. I never thought how to use the face selection on pattern features. Simple and efficient.

Thanks!

The method is alright may be a little bit lighter than my approach. But still when i increase the cell count the way I need it. I experience the same problem as before. Either my computer can't handle it because my CPU is like 99% loaded when making changes or I am coming to the limit of the surface count for Fusion 360 or may be its both. I will try to use Mesh Mixer to conjure something out of it. Thanks for the help.

Only this much.

As soon as I increase cell count and make the walls of the cell 0.4mm. Changes take as long as the other approach on my machine I can barely tell the difference. I can't understand on the fundamental level why is that happening. It's probably because my PC doesn't have enough RAM or the CPU is way too old to make all the calculations. Thanks for the help.
