development sheet with cutting of revolution

[rikk]

Bye to all,
I haven't written here in the forum for a while, but I've been reading it for a few weeks. I am trying to learn how to use solidworks 2011.

I'm trying to try out all the functions, but what I care about is the plates.

In this regard, I tried to build a liquid tank. those cellars to understand.

for the creation of the stem, the top hat and the bottom, there is no problem. I am also correct.

When I build my legs, the development problem has arisen. . .

How are these legs made?
We imagine that we have an omega profile (so open) that from the bottom of the tank comes to the ground. The bottom is radiated.
so I created the sketch, I extruded it, and then cut with the special function sheet cutting revolution (according to the profile of the bottom tank).
I find myself therefore with the sheet leg perfectly adherent to the curve of the bottom of the tank.
But this development of the leg must be cut with laser.
and here the problem. solidworks doesn't develop it.. .

Now I don't have the file under my hand and I can't post it... I can't do it by night.

Anyway, does anyone have any ideas on a possible solution?

I thank everyone who will respond in advance. :finger:

post an image of what you would like to get. .also an image recovered from the internet.
definitely the cut of revolution created faces that are not orthogonal.
solidworks sheets must always have constant thickness and faces on the side of the orthogonal thickness, otherwise it does not develop anything.

Yes, that's the problem.. .
Some faces are not orthogonal.

I attach a random image taken from the internet. here the bottom is completely bombed. I mean it slowly and with a radius of 100mm. but it changes little.

1) make your foot full and cut it with the revolution.
2) make a thin cut through its height, so that the foot is a separate sheet (low 0.2 mm)
3) use the convertin sheet and use only the external face.

thanks soliduser!! !

I followed your advice, but halfway through the work I tried to do something else.

I created an extruded surface with loft, I put it with the special "filled surface" function and then converted it into sheet metal.

Now it works! !

one thing I didn't say is that the leg has variable section but doesn't change the sense of speech.

Thank you so much!! !

Wow, I just finished modeling and reading your comment. . .
We did the same thing... :smile:
