are the limits of the axis of which you speak concerning those for lassembly of separate parts making coincidence faces, axes, edges etc. or are also constraints intended as references to the geometry between the parts for which it is possible to make of the top-down modeling where a parent part commands a daughter and there is never possibility of interference by changing one of the two?
the bonds of assemblies concern assembly (in practice when moving a part or creating a mechanism the elements remain bound).
When you move an object or part of it you can select more objects together. es: select with a selection box 2 coaxial holes 1 screw and a nut and move them to the right of 50mm. or extend a beam and move together the last 2 holes and a team. or even increase the height of a locker, moving together the top, handles, stretching sides, back and doors.
you have to see from time to time, so it is clear that in the example of the sheet gronday pass from a profile to omega to a completely different one could interfere with the functions of development, lacerations etc., both with sc and with swx (or if, create etc) but if you create for example a sweep or a loft also complex profiles or paths you can almost always change them also heavyly (using the head eh...) that at the end.
what does not work in fact, is the modification of particular surfaces, for example a ring with bright square section that twists (sweep or loft) I can create it with spaceclaim, but I can no longer change the diameter of the ring according to the size of the fingers, which instead a feature based egregiamente since it is as if it reconstructed everything from the first operation repeating everything.
do the omega then change it in circle (and it is not even necessary to delete the old geometry but just convert it to the flight in construction lines) and when you leave you have instead of the gutter a tube. with sc you delete everything and do it again. with swx you take 5 seconds and with sc you need the 10 minutes you used the first time, and if you want to pass to the square profile as you need the 10 minutes again. I extremized but the concept seems clear to me.
Yes, I agree, you're less, but only if you have clear ideas... Of course if you change from omega to circle maybe you didn't have them quite clear!
I'd have to try a cad like a sc to know, but I've been through these paturnies.
.
But what I don't understand, with regard to creation from scratch (and simplifying), is why you have to do before me to create for example a coil pipe. you have to profile the section, you have to do the helical path, you have to set the profile size and section exactly as I do.
I would be less on certain things, and on others we would be the same time.
reasons why sc takes less time to create certain details/assemblies:
-do not put constraints during design
-usi 2-3 commands, no cascading menu
-you can create a set while modeling a particular (for example you can split a single solid into more details)
- See what you're doing while you do it interactively (no x+ commands, measures, constraints and then send and see what it did! )
-you can use a dxf with 3 views to turn it into solid, in some cases you can take 2-3 minutes to make a fairly complex figure
- has intuitive commands, so it is just faster the "problem-think-action-solution" flow. I mean, for what is my experience, you don't get stuck thinking "ok... and how do I do it? with what function? "
But in my opinion the focus is not on which system is faster (which then to do what? depends!), but:
-modify a 3d (and use a 2d) as if you had done it <-- this is the first fundamental advantage, the reason why it was born
-I would create a prototype faster <---- no assemblies and constraints during modeling, only remains the "lude" and creative part
- a 2-day neophyte is able to create quite complex geometries, so it is particularly suitable for those who are not a full-time designer, and has no time to learn a feature based.
- if I am a third party, I have to open the models of my client, change them slightly and work them (e.g. sheet development for cutting and bending) for a matter of costs and times is by far the optimal solution. other software would be less indicated and more expensive (they do more than necessary)
are then of the idea that hardly the changes require to switch from a centrifugal pump to a conveyor belt, so if the changes are within the same "genre" of product, i.e. larger pump, greater number of palettes etc, rather than longer conveyor belt, less wide etc then changes of a well-made cad model "parametric" twist any contextual.
When a potential client asks me the sc io demonstration first I ask him what the company is doing for. If the answer is "we produce centrifugal pumps and we need a cad to design the different versions of a pump" I reply "to sw, if, proe, ... "
sc would definitely be unsuitable. different speech if you design structures, frames, etc. that are far more suitable for sc
iho the main advantage is the lightness of the models so the ability to manage very large assemblies. on the management of imported models it seems to me that functions of direct modeling of se and nx completely cancel the advantages of contextuals.
do the same thing, but there is a discreet cost advantage from sc! we have customers who import a step geometry of customers and press "develop" a hundred times a day, some of these times are forced to change a fold with a soldering or vice versa, or change a little something. I'm sure there's no better solution at the same price.
