hello to all I am again here to propose my gap... recently I am creating sheets with the "loft" function and now I would like to make an extruded "normal" cut to the thickness but I can't do it. the sheet in question is curved and its curvature is different between high and low... now I was wondering: the normal extruded cut to the profile will be possible or do I have to do the stretch-cut-fill?

Thank you all.

in order to make the normal cut from the bent (called in this case) the two curvatures even if of different radius must be concentric. in practice that piece of sheet metal must be a "branch" of rectum cone. and if you think about it is right because it is the only way to really get normal in all the infinite points of thickness.
otherwise yes, with distendi-ripiega you can do this but the difficulty of determining how the shape of the cut should be when folded and therefore draw the correct sketch on the development.

I use little loft sheet just because it often gives me problems with later cuts. I usually prefer to build with the surfaces already correctly squared (folded) the detail and then trim it.
If you have no experience and you don't understand what I mean by posting the file I show you what I mean.

in your case it does not make you normal cut probably because both areas have no material behind. I did some evidence on a sheet loft, straight piece with different curve. the rectangular window makes me like normal cut, while the upper bevels do not and I have to do them as passing cut.

I imagined it! clearly they are not equal curves nor with the usual radiation....I managed to realize them but with the cut as if it was a solid milled and not normal to the profile.

Now I also try the window on my example then I tell you...the thing is a little curious in some ways.... !

Thank you.

Right... milled on the floor where you put yourself and the sheet instead of having the normal hair at the curvature become a knife because it enters a fixed plane... even to me where by mistake it does so, while the window is ok.

In this case it makes me the normal cut does it but look how it combines the sheet!
Go to the crazy! :biggrin::biggrin:

Saddled makes some shark teeth. Of course I'm in charge. I always said that the inventor sheet module will never beat him swx. :biggrin:

great mecc.. Maybe that's better!
Give me an eye!

Thank you.

...if you want to try with inventor, by curiosity!

the round hole is ok and also the bevel, but still that toothed crap:tongue:
but take away another doubt, please: is it orthodox to use the bevel that is under "functions" in the sheet metal parts without creating mess? or is it better to use only spigolo treatment that is under "lamiera"?

...no because that under "functions" is much more versatile having more possibilities of variation!

Thank you.

you can use it, just look how the final processing results. Let's say it's a swx mental saw. Why do two commands where often in the sheets does not work the treatment of edge?

sure that with the last file I posted with the bevels everything works but if you increase the bevel, example 120x20mm or even less, it works goes wrong.. .
We say that with loft and extruded cut there are limits!

Mechanicalmg if you have time and chance could you do a test on inventor?

Hello and thank you.

I answer to all readers of this topic that is not a problem of solidworks but parasolid.
ne solid edge, ne nx or other cad that use parasolid as a solid modeler, will succeed in correctly cutting your piece.
allego solution.
This is a case to report to the assistance to make an implementation on the algorithm that in this case does not take into account this geometry.

I would like to know according to which cases or commands consider superior inventor.

I always modeled years ago with inventor quietly what with swx you can do now. has always had the very developed sheet metal tool. swx has late and now we are finally there....with some kiss here and there but we are. It's like the concept of multilamiera ie multibody sheet... He wasn't there before. but it is so difficult to understand that if we do the parts and we put them in a set we do not manage anything if we cannot put the sheets in correlation? And yet with inventor, even if working together, it was not so difficult to exploit the lines and curves of the other plates. the treatment of edges and other processes that are now in swx were present 2 or 3 years before inv.

Then, with time, things have changed. I live almost only by swx so... or so or so, so much so that I now struggle to use inv. with years I enjoyed swx.

pssss.... attach the solution grz:biggrin: You've escaped the ditino...:tongue:

What makes me look like you write caxxate.
write without being sure or aware of the subject.
Do you know why these two commands exist?
I'll tell you.
that in the modeling toolbar, it performs only topologic controls, while that in the sheet toolbar also performs controls so that the geometry that turns out is always compatible with the rules of the sheet, that is constant thickness and no bevel on the edges of the thickness.
therefore they are not mental saws, but controls against designers who of sheet metal know little.

You said nothing to justify what you write.
Do some examples of the type, with iv9 doing this while sw2008 no.
the sheet metal loft in iv arrived or the year after or 2.
This is just an example.
I have never heard of strong iv in the sheet, if yes, then it did not detect such.

in fact I have the doubt and I said to try to see the differences. since some edges cannot be treated by the advanced command of the plates to make a bevel. the loft model placed is not possible to smooth it on the curved side with the treatment of edges straight sides at 90° si. the piece calandrato (variable ray) has its problems, such as the serrated cutting of parasolid technology.
I'll tell you.
that in the modeling toolbar, it performs only topologic controls, while that in the sheet toolbar also performs controls so that the geometry that turns out is always compatible with the rules of the sheet, that is constant thickness and no bevel on the edges of the thickness.
therefore they are not mental saws, but controls against designers who of sheet metal know little.
now I am sure, translated loses geometric texture the bevel made with the bevel of solids.

remains the problem of how to smooth certain edges. or there are alternative solutions, or you quote differently with the error of 0.01 or you do not bevel the piece because swx does not.
 
Of course this question seemed like a crap, but it's a big problem! I still did not understand how you could smooth the corners properly. ....
