Aid for building item 3d

[criV]

Hello!
I hope I'm in the right section. I use autocad 2012 and I have to do this design
but I have 2 problems:

1-in the vertical part, I did in 2d the vertical arc profile only that when I extrude it turns out empty and not full! how can I do? ?

2-in the lower wall then there is that "s"-shaped fitting but I just can't connect the two solids. How can I do that? ?

Thank you so much!

build the solid with parallelepipeds, join and then use fitting on the edges.

 

[Cristallo]

the streets are so many.
build the profile (closed polyline) of the bracket view on the side (the one in shape si s) and then extrude it.
build the triangular part and extrude it.
join the two solids and then remove the extra parts (holes and round part of the upper arch)

but there can be many other ways. you just need to work with closed polylines (which extruded generate solids) and not with open elements (which extruded generate surfaces)

quoting crystal

p.s. how nice to read

...build in the plant the triangular part and extrude it. . .

even with presspull it already extrudes laundry.. .

It is true that there are countless ways to build that model, but for the high part I find it useless to build the 2d to extrude, besides with the breaking of constantly changing ucs, better to draw directly in 3d.

I would do as in this example (with catsum measures).

You know what?

You're my savior! :biggrin: thank you! after I try to follow your method!
is that I have recently learned (the basic things) of the 3d and therefore with this model (for me a little complex) I did not know well what way to undertake!
thanks to all for the advice... very kind as always! :smile:

:biggrin: te la cavicchi con il 3d :biggrin:
this is a way with construction for extrusion

(so buttons with my hand that I am also learning the prog. for animated gifs! :tongue

 

[GP.]

But "paint" uses it very well...

I'm just a good paintsmith. :tongue:

...grazie!...

Please. :smile:
as you see the ways are endless, everyone has their preferences.
Good job.. .

...to also learn the prog. for the animated gifs!...

see, however, to increase the resolution, 250x156 is a little lean.
I did not become blind at the time when there could be the underlying reason and I would not like to become it now. :biggrin:

 

[criV]

At the end I did it: ...you were right to do it directly in 3d was much easier...in fact I would say at all difficult! It's just a week I took cad 3d so I think I still have to learn some basic things:
Thanks again to everyone!

 

[criV]

I'm back! Obviously autocad takes out the worst of me..to doing the cad3d and I am at a point "dead"
That's what I should do
I created two solids but I don't understand how the hell I have to tell them to get that kind of connection!
Thank you

Bye!

It is not that from that design you understand the problem...however. . . once drawn the base that seems to me to the eye a parallelepiped then the solid perpendicular on the shape "facemo" triangular :smile: and moved into "advanced" of 2 mm (as drawing, it seems to me to understand) you have to do nothing other than to combine the 2 solids and to connect of 5 mm "davanti" and 2 mm "back"



I hope I've been helpful

:smile:

 

[GP.]

I don't see what can change compared to the solid beginning of the discussion, in the present case you have to clearly join the two you created to be able to perform the fittings.

rather I see the problem of the connection of the shifted part of 2 mm, if the connection should start accurately from the base solid edge the radius could not be 2 mm as the walls of the above are not vertical.

If so you see the example (measures are always at spans):

sleep makesa...

We didn't realize you were an engineer.

hi gp.I am new to the forum and I intrufolate myself in the discussion. . .
I'm also trying to take some confidence with the site in the meantime.

I think he didn't join the solids, and that's why he can't tell :wink:

However, I think the solid in question is something like this:mixed:

 

[GP.]

...comunque credo che il solido in questione sia una cosa del genere...

Um... Maybe you're right, I should have magnified the image. :tongue:

I think the beautiful cri didn't join the solids, too.



p.s.: Welcome to the forum. :smile:

the limit is given by the upload limit of cad3d. I managed to contain the file size only by lowering the resolution
I should have captured a window and not the screen, but I thought you could cut out later (which I couldn't do)
