elliptical cone with axis on one of the fires

[Joseph]

Let's try to cheat autocad.
As the loft command does not accept as the second and last cross section the point, in the position b (b is not on the vertical of the fire but to a quarter of the axis, but reasoning does not change) we draw a very small radius circle (eg. 0.01), we select as cross sections the base ellipse and the above circle and we complete the loft command with the options that we interest.
in this way you also delete the intermediate cross section.
greetings
Joseph

Who says that? It is not true at all...just the other day at a course I shaped a dodecaedro to my lanes using base pentagons and top points

Tristan, you couldn't get there before we "do it"

It's true, ellipse + point acts!!! :biggrin:


p.s. however we do not yet know that version uses janluca, there is to pay attention to set continuity = g0

oops:biggrin:
Did I interrupt the Mass?

p.s. however we do not know yet that version uses janluca

Since he speaks of loft, I can say with certainty that he uses at least 2007 indi so... :finger:

 

[Joseph]

It seemed strange to me that he rejected the point, but unfortunately today he continued to give me error. tonight I reverified and the procedure works; Who knows what I had set!
Anyway thank you for having me reread the guide better.

Why do you say that? "to pay attention to continuity=g0" ?

I bet an answer, because Monday gp is late playing tressettes in front of a few quarters of the good one.

g0 is the continuity of position, in the sense that you force the passage of the surface through the generating curves.

I use autocad 2008, however not to be pignolo but since the method I used is very simple and it works because to complicate life with very long and complicated procedures, with dissected, inclined and what else? and then tristan simplified it even more, to be honest I had not thought of loft + base + point, so even better...:smile:

 

[AntonioV]

to complicate life with very long and complicated procedures

Because the forum is like a lab, which goes beyond the pedisseous response to the individual user.

you gave us the cue, and of this we thank you, and we experience other: learn every day something new thanks to you users.

a quarter at a time.. .

g0 is the continuity of position, in the sense that you force the passage of the surface through the generating curves.

exact, but in 2008 this problem did not arise. in 2008 it is enough to give the loft "only cross sections" with "regatta" option

 

[AntonioV]

with "regatta" option

Now that you make me think, joseph's makeup could apply in the case of _rulesurf after high surftab1.

He embellished it as a start and the circle there on top as a destination, and he creates an exquisite "cialda" overturned. . .

with 2011 default that figure is built with continuity = g1, there will be some variable to set. . .

 

[Ezio Olivato]

I'm gonna have to play with the cones. Good to know.

ok, I am happy to have given the point :biggrin:, and however it seems a nonsense, for 10 years I use autocad I have created absurd 3d solids and forms of all kinds, but the most difficult thing to draw was this cone with a shifted axis: crazy!
