revolution with offset line

[pizzaf40]

Hello, everyone!

I have a problem with proe wf3.

I have a sketch drawn (an open curve, not closed). I do the offset of this and it creates my offset line.

Now I should create the solid of revolution (or the surface of revolution I love the same) of the offset line. The problem is she doesn't.

the only way I found is to recalculate the line with a sketch, but this is very uncomfortable because it is not a constant but variable offset sketch. ..this creates curves that aren't exactly geometric so I can't recalculate exactly. and anyway, in general, if I do the offset of an arc (for example), the line I get as a result is no longer identifiable as an arc...I think it makes a spline to the desired offset distance, so also sketching and using the arc as a reference, I do not mathematically refer to an arc

possible that there is no way to use my offset line for a revolution?

thank you for any answer.

Hi.

the correct method is to perform the revolution of the initial sketch line (magari surface) and then perform the offset of that surface.

if what you mean instead is a translation of the revolution creates the revolution on the initial sketch lie and then perform a special copy/paste with the activated rotation options.

I hope I've been useful and if I've understood something, send me an example.

the idea is that it is equivalent to the offset of a surface.
about this I have a question though:

Can I do the offset of a surface using the variable offset option? the offset of the line I made imposing the distances turned on certain points...the offset variable distance for a surface works the same way?

Hi.

Sorry, but I didn't see it was variable.

the alternative solution I propose is a variable section sweep with trajectory of origin the hypothetical axis of revolution and as a curve guide your variable offset line.

I'll give you an example.

otherwise following what you did previously you could remove the references of "ricalco" from the second sketch and with double click on the spline of turns out to redefine the accuracy with the smooth commands, add points or edit with excel the points by chart.

Okay, I'm coming home tonight, I'm unloading your attachment and trying to apply your advice! Meanwhile thank you so much for the help...in any case I give you news!

I did it!

compared to a revolution has the flaw that cannot be used lines that end on the axis itself (my ones are actually also normal to the axis), but fortunately in my case the extremes were sufficiently simple to be able to do them in sketches with good references....so I made the revolution to the extremes and the sez sweep variable in the middle!

Thank you so much!

Hi.

if the extremes are closing plates you can use the option to close the ends (if you use the surface vss) and then solidify or thicken.

alternative is as you did but all of surfaces (without references but intersecting each other) a couple of merges and solidify and thicken.

Anyway, I'm glad you were useful at the first shot.
