Draw 3D arc point to point

Rich O Brien

Something like this?

My experience here with trying to use TOS inferencing is that the same inference, drawn from the same edge, can lead to seemingly contradictory results, though both can be 'logical'.
3D ARC-TOS-1.JPG
The first segment is drawn, sloping up, and the second is meant to continue this as if tangent. The continue along edge inference is locked and the resulting line slopes up and then down, even though the first was only sloping up. It is as if at some point the tool says OK, this line is sloping down, which of course it is: any up sloping line is also sloping down from the other end.

That sure looks like it, Rich.

Fredo Tools Curvishear. I will go-a-looking.

Thank you.

And thank you, gilles, I will try that.

I wasn't looking for this, however, you demo was impressive. It is hard to keep up with all the plugins and what exactly they will do.

So thanks Rich

Curvishear !!
I forgot this one, yes too much plugins.

jeff hammond

oh wait.. if curvishear is doing it then I guess I didn't actually realize what you wanted.

I was picturing 3 different radius arcs being tangent at the start point then being applied to a curved surface..
(which is possible to do btw.. just not with plugins (yet))

please ignore my post in the thread

Your post was not and will not be ignored. The surface was made from the 2d arcs as something upon which to more easily build the 3d arcs and indeed seemed to get most of the job done: TOS then had a surface upon which to draw and I still think could do it. But CurviShear obviates the need for the surface, and I really wanted the 3d arcs alone, anyway.

Tanks again to all tipsters.

Well, shoot! I forgot about Curvishear, too. How in the world is anyone supposed to remember all these plugins, anyway?

Ditto to that! I have less than 30 plugins installed but have tested everyone and keep them sorted by category so I can easily install when needed.

Every method has merit. Mine was the lazy way.

Does that mean you owe me a pint?

Happy Paddy's Day everyone

Dave R

Yes, I do and if you're on your way, I'll get it poured.

Happy Paddy's Day to you, too.

Hi,

@matt
that's already possible with tools on surface

which tool in TOS are you using? arc on surface?
if so, try using a simple line on surface.. click on the start point then the end point and that's it.
be an arc)

I Have tried it with the line but it does not work. I do not know if I did something wrong.

I'm with you Charly. I've tried this before also and found that drawing an arc on surface with TOS makes the tool get confused especially if the curved face is totally not in view of the user... [ie: having to orbit the model to continue drawing.]

I do like Rich's use of Curvishear though; that could be the way to do it.
