How do I Construct this shape?

Postby davewong » Tue Jan 21, 2020 10:09 pm

HI All,

May I know if anyone knows how to construct this shape and maybe give me a guide on how to construct it?

It seems easy but I really can't figure out how to achieve this shape. Since the bottom isn't round, it's hard to just draw half and follow me it.


Anyone?

Something like this:

Edges for profiles shown selected. I copied the profiles to give me a better idea of the overall shape. Curviloft to create the skin on the left. Copy and flip the skin to make the other three sections. Explode the resulting groups and soften the edges.

I will try now. But will it be possible to be made into a Solid? As I want to 3d-print it later...

Hi Sorry, may I have a step by step on how to achieve it? I downloaded Curviloft but I am so lost as to how to create the lines to even start using Curviloft to do anything :(

Thanks!

Just select the Surface and Use Joint PushPull by Fredo!
look all the tutorial (but your case is 8.42... minutes )

With the method of the Extrude Tools By Tig

Bezier Splines

Trick is drawing curves on a rectangular surface (here the image) or a simple rectangle then erase the unwanted...or like follow a Copy / Move! ;)

you can use only 3 curves (so make 2 clicks on the second curve - here it's 4 curves)

So after the JPP for thickness etc...
Maybe base must be trimed depending of what do you want...
