Subdividing spline drawing

Anonymous

I do a sketch with splines

Snap18.jpgSnap20.jpgSnap19.jpg

I extrude it

I mirror it as a duplicate

I fill hole on the bottom and top of the Body

I subdivide it

 

The Question can it be divided like the sculpture primitives?

I'm trying to make organic style forms for 3D printing.  I am new to this so don't know much about much.

Hi,

 

No, to close a hole in such way, you will have to make it manually, and it's going to be such a pain with no guarantee that it will work

Could you share a picture of what you're trying to  achieve by this so that we might offer a better approach

Well.....

I'm learning Fusion 360 because a maker's space for hobbies has lasers, cad, and 3D machines that all are using Fusion.  I did these in Blender quite a while ago and it looks like I'm going to have to refresh/learn Blender again along with Fusion 360 for the cad/cam.  I could kick myself for forgetting Blender cause it has a much higher learning curve.

I see that there is great help on this forum and a great product.  I just suspect Fusion 360 has a long ways to go in the sculpture mode unless I'm missing a lot.

Thanks.

These shapes can be easily done in Fusion, you just need to figure out what the right approach is

Which part of these shapes do you have a problem with?

I'll make a screencast on how to make it

If @Anonymous did these in Blender then I can tell you from over 15 years of using Blender that these are much easier and faster to do in Blender than in Fusion 360.

Blender has a vastly improved workflow and toolset for polygon models. There is really no comparison!

 

@Anonymous Try to re-learn Blender for these organic models. If you still want to use Fusion 360 then you can export your quad mesh from Blender into Fusion 360 and convert it into a T-Spline and then into a solid without loss of fidelity!

The question is then what you want to do with it in Fusion 360. If you want to 3D print these then Blender also has a much better 3D printing toolset than Fusion 360. You can check wall thickness etc. Also the .stl is created from the subdivided mesh, meaning it really follows the topology of the control mesh. If theres any faceting left this makes much nicer prints with lower poly contused than than what you get from a solid in Fusion 360.

 

If on the other hand you want to decorate a wooden surface with these ornaments and want to machine these then the Blender->.obj->Fusion 360->T-Spline->BRep(NURBS)->CAM workflow is pretty sweet.

Here is a screencast that I believe it's final result to pretty good

I hope it helps

This is a very cool way to do this except I've run into a problem that you don't seem to have.

 

To do the 2nd. Sketch after I unfold the sheet I need to have it aligned with the view otherwise I either can't get it to join with the first sketch or it doesn't join right.

 

Snap35.jpgSnap36.jpgSnap37.jpgSnap38.jpg

So the question is how to get that parallel to the screen so the 2nd. Sketch will join?

I may should have put this in another message but it seems like you would know my problem here.

There is no need to make it parallel to the screen, because you only have to create a 2D sketch on the surface of the unfolded flange, and then extrude it, and set the operation in the dialog box to join
