How to loft this?

[Anonymous]

Loft doesn't work on this..How can I make the upper case loft to base? Or any other suggestion? Thanks

To get proper answers, I think you'll need to provide some more details, and preferrably (if you can) export a .f3d file of the design and attach it to a post here.

From the picture this looks rather simple, but it is also not entirely clear why you need to loft it. Can't you get away with regular extrusions?

Is the loft supposed to go between the highlighted profiles in your picture?

Thanks for the response!

Okay lets make it clear. I'm trying to make a box for my arduino. The picture below is the lower case of the box. I want to maket he upper case of the box. I can make a rectangle on the top of it and extrude without problem but the question is the organic shapes.

What if I want to make upper case of the box like a dome not a rectangle? How would you start designing it? In Maya, you can reshape your model nurbs points, vertex, vertices etc.. Since I have very little experience in 3D design I don't know where to start and how to draw it.

Well, I think perhaps you'd need to go through some tutorials to get a grip on the basics.

That said, there are many methods you can use to do this. For organic shapes, you can use t-splines in Fusion 360, and combine those with objects created from sketches, but you can (as you mentioned) also use lofts to make organic/flowing shapes.

A dome can be created by sketching a half circle and then revolving it, but to mate that to a rectangular shape like your bottom case, you'd need some transition. You can also create a rounded shape by lofting just a few sketch curves.

The very simplest method to create a dome-like lid for a box is to loft a surface to a point, and then thicken that and combine cut with the bottom half. I've attached a very simple example, it's just a handful of operations on the timeline. The resulting shape has creased edges from the corners of the bottom half, but you could of course loft with rails and more sketches to avoid that. As I said, this is just a very basic example.

Wow thats what I mean.. Still not sure how did you do that though! 😃 Yes I need some tutorials for sure!

Look how stupid did I make it..I cant even use fillet now 😃
