Is that possible ??

[budi67]

Hi all,

Sorry for my english, i'm French.

I try to make a Dome of R2-D2, i managed to create the panels of the top, but now I should make a hole on a face of one of these panels, is it possible?

The panels

The hole

As the surface is spherical!! I don't found

A big thanks

Best regards,

Just create a sketch and project the edges of one panels and dimension the circle off of the reference geometry you project into the sketch. Then extrude cut using the circle.

A big thanks for your rapid answer.

I will try this

Here's a picture that might help, the sizes are not correct but should give you an idea how to construct your sketch.

I don't understand all, but I has to redo at first the dome because I had imported it of 123d.

But by making the dome with a revolution, the top is not round, any idéa ?

[HughesTooling]

Make sure you have a vertical\horizontal constraint between the arc centre, arc end and the axis to revolve around.

Screencast demo.

Bonjour, pour votre information nous avons également un forum en français: http://forums.autodesk.com/t5/fusion-360-francais/bd-p/331

[budi67]

Ok, it's all good, it's my fault, the dome is not a circle but a ellipse.

A big thanks

@patrick.emin Merci beaucoup, j'avais vue pour le forum Français, mais généralement quand je suis sur forum anglais avec une section Française, celle-ci ne remporte pas un franc succés !!!

En tout cas merci, vas maintenant falloir que je vois ce truc de projection, car je doit avoué que je nage !!

[budi67]

I have tryed with the projection but It is not what I would like.

Can you File>Export and then Attach your *.f3d file here to a Reply?

[budi67]

I join the file.

I also noticed, by making a cutting in view that my panels are not just, of needs they one the just air, but below it crosses it with the dome.
Seen that I begin, me has to not make the operations correctly.

[I_Forge_KC]

This is one way to do this.

If the dome shape was perfectly round, I would just use a tangent constraint on the line - but because it is ellipsoidal, the tangent constraint does not work. By selecting the two end points of the curve, I can approximate what the slope would be between them.

Note that the distance between the two lines is of no consequence as long as your extrude cut extends far enough.

This method can be adapted to work at a specific angle as well (for example 45 degrees). In that case the floating line would be dimensioned against a vertical or horizontal line to give the degree measurement.

Hi @budi67,

Here you go. Just reverse engineer it to see what I did. Let me know if you have any question.

Cheers / Ben

Hole feature is nice but can't be reposition, here's my way ( I've used Ben's file):

[budi67]

It is really great!!!

A big thanks to all for your answers, i see that thomorrow

In any case fusion is really brilliant !!

I would not miss to hold you informed

[budi67]

Sorry but i have another problem, i have try to make panels at the bottom Dome.

I tried a method which I considered just, but the measures are not correct.

The 2 etching are not parallel

There, I swim !!, it is all the same infuriating not to find.

[budi67]

It is possible, I found this ==> https://gallery.autodesk.com/fusion360/projects/r2-d2-dome

I badly has to resound because of the rounding arghhhhh

[budi67]

What are think about this ?

Ok it's a long procedure, i try what I consider just still by not knowing the tricks

The distances are not still equal.
Do they can beings really parallel?

[budi67]

I have still tried, but it is not still parallel

[budi67]

Hi all,

I realized that it is my ellipse which was not good

I almost ended the dome, still the panels of the top.

But I need your expert help, I have another part to be modelled but I do not arrive there, I have already tried several times, but i don't know how to make.

I does not even know by or to begin

One thank you beforehand
