free form using triangle

[marco.bresson]

Hello, 

I would like to create a free form using triangles instead of rectangles (so, a sort of mesh). I can't find how to change this settings.

The goal here is to have flat surface when moving all the points in the 3d space 🙂

[artemSIV]

when creating a sketch, you can select a 3d sketch and arrange the points in space as you need

[TrippyLighting]

Can you be a bit more specific as to what you are trying to model?

An image can speak a thousand words 🙂

[marco.bresson]

thuis is the thing i want to model

the problem with 3d sketch is that i do not have the possibility to create a mesh with rectangular patern ^^'

[TrippyLighting]

I am not exactly sure where you see a rectangular pattern in this object.

[marco.bresson]

I do need a rectangular patern for the 3d sketch to build the "default parallelepiped" and then, moving all the point one by one !

The free form object was really helpful because it was really convenient exept that it uses 4 sided polygones, hence creating not flat surfaces 🙂

here I show only the principle of construction

[marco.bresson]

Wow.

Actually, i am impressed on how much time you spent helping a total stranger ! Thanks a lot ❤️

I will try this out tomorrow morning !

Have a great day (or night, if you are in Europe)

Hello !

I am having a little issue now ... I don't really know how to thicken my model. I mean, the thicken feature is not doing the job correctly because we can see some solid going outside the outter shape ! I hope it makes sense and as a picture worth a thousand words : (All surfaces outlined in red are facing the same direction)

I tried to stitch all the surfaces but it didn t worked either

[TrippyLighting]

That screenshot looks like a mess 😉

Can you export your model as a .f3d and attach it to the next post?

[artemSIV]

STITCH first, then SHELL operation

Here it is :

@artemSIV I already tried this but i have an error :

"the body could not be repaired after deleting faces. Try changing the selection, or use the Delete tool in the Patch Workspace to delete geometry without repairing the gap"

I don't really understand this error by the way ^^'

[artemSIV]

Then let's see the file and write what wall thickness you want

[marco.bresson]

Something about 2mm would be great 😄
Thanks you

[artemSIV]

I did it in netfabb, and it’s much more convenient

[TrippyLighting]

I think "convenient" is not how I'd describe it. This just cannot be done with thickening or shelling in Fusion 360. As the end result is likely to be 3D printed, using Netfabb or Meshixer is a good workaround.

[marco.bresson]

Hello !

Thank you really much @artemSIV ! But the logiciel seems to be a paid software whereas fusion360 is free for student (which i am). Furthermore, it needs 64GB of RAM to run according to https://knowledge.autodesk.com/support/netfabb/learn-explore/caas/sfdcarticles/sfdcarticles/System-r....

But i do have meshmixer, i will try to use this software to do what i want as @TrippyLighting suggested !

Hi, @marco.bresson,

Netfabb runs just fine with less. The 64 GB are a production-typical figure for projects with large amounts of parts, high triangle count (several ten millions and up), large slicing jobs, latticing, and so on.

Also, Netfabb still contains the free (no-cost) unlicensed mode, http://blogs.autodesk.com/netfabb/2016/10/18/netfabb-basic-is-now-just-netfabb/, and there's a free trial available (https://www.autodesk.com/products/netfabb/free-trial) that reverts to that same unlicensed mode when the trial expires. (You can also choose to never start the trial in the first place.)

Best regards,

Steffen
