propongo un benchmark, if you go and without any controversy.
you must realize a semi-box, as in the attached figure, explaining with what features.

I find the exercise interesting, it was nothing else to assess the approach to modeling.
then maybe every system has its own features that characterize the executive technique, but in my experience I have seen that maybe there are techniques somehow transferable.
p.s.: I with solidworks did so

I didn't understand the usefulness of the exercise because it seems trivial, maybe I miss something:
I, with solid edge, did this:
1) extrusion with strip corner
2) External connection r6
3) emptying sp.3
4) Sketch creation for exhaust
5) excavation guided by curve, using as curve the existing edge obtained by emptying.

personally I have already found interesting the difference in the modeling of the exhaust. However, they can be used in both software.
I think our two objects are different...

you are right, I had made the two big r110 rays instead of r160, and the height 10 instead of 15 (maybe I was thinking about the coffee break!!!)

two answers and already two different approaches. .
I with nx have adopted a further approach, typical of nx, perhaps a little more complex but absolutely bomb proof:
Extrusion
draft (the profile has maximum dimensions, those of drawing 2d, on top)
solid extract>offset faces (which I used to create exhaust)
emptying
subtraction
with nx I could have done both the solutions shown but for reasons I will show you then I followed a different road and, again, typical of nx.
I ask you to show me the initial sketch because in nx I did so
cacciatorino
Guest
here is the sketch in itself

is it necessary to trim the curves?
cacciatorino
Guest
I didn't understand the question well. I designed 4 arches and the system automatically places the bonds of coincidence between the end of one and the beginning of the adjacent one, then I gave him the bonds of tangency and quotated the rays and centers of the two extremes. .

as you see my sketch is different, there are two circumferences, two arches and a line, all 'active' and intersect.
nx is very flexible, if you want, for example extruding edges, lines or other entities, you don't have to 'copy' them in sketches. in the attached image I am making an extrusion of a part of a line (it is not a sketch), part of a edge and so on... and it's all parametric!
cacciatorino
Guest
Yeah, it's a available mode, though, I only use in special cases.
LaboratorioDieci

Also in solidworks it is not necessary to trim the circles, but in this way the sketch will include 5 areas that will be selected one by one to make extrusion.
with respect to the use of entities other than a sketch (faces to capture the boundary, edges, ...) also with sw it is possible

also 'mixed'? a piece of one piece of the other? Is there a difference between edges and edges of the face?

You take us slowly into the trap until you find that application case that happens once every 500 years when the 15000 euro cad is better than the 5000? :
It's obvious that there's a point where the high-end cad has more mid-range functions, otherwise it would have already been out of the market for a lifetime.
ceschi1959

absolutely not, sincerely. I'm not going to race to see who has it anymore...
I just want to say that some functions that has nx, if used in a 'creative' way make the job faster and more robust.
In my work I often have to overwhelm what I did and if I had no proper tools I should start from scratch every time.
If instead of the form proposed to 'egg' the customer at a time asked for any form, with the features proposed, I refer particularly to the extrusions of scroll or sweep, would you succeed in changing the detail quickly?
look at the attached file. . .
I modified the extension, it's actually a 7z.

I think it's something I can't do in those terms. I am still puzzled about the ends of the discussion you are proposing. :unsures:

the spirit of my intervention caught him in full @shirokko, and it was aimed at making it clear that many passages to different cads create, at best, discontent or even fail because they tend to transfer concepts and techniques not suitable for the instrument.
That's all.
LaboratorioDieci

regarding the selection of faces to capture the edges I said a nonsense, at least for the basic extrusions. the replacement of a curve inside the sketch is possible, of a contour composed of several curves instead not.

The thing that indisposes me a little is that you propose us a seemingly trivial exercise without making us understand where you want to finish. then after making us spend time following you completely change the cards at the table and the goal.
If you had been clear from the beginning I would not have committed twenty minutes of my time to recreate that form, I would have dedicated myself to something else. That's what I find irritating in this discussion.
