Hello everyone I should create a v in stainless steel and then cut it laser, how do you recommend doing it? what procedure? ø 219.1 I train you a sample to understand better what I'm talking about.. .

created from structural members turned into sheet metal at a later time.[youtube]p3l1kwt5x8c[/youtube]
 
mike I saw the video, it was very satisfying compliments thanks to you I managed to do so many things...we take care of piping and these things are on the agenda now I miss to understand how to make a curve, I today tried to perform curves but I don't understand how to do it...

Thank you for enjoying my contribution.
with the prg 3d it takes imagination, thinks that the video posted I did it "in real time", I had never designed a pz like that, but the experience counts.
about the curve, take a look at youtube there are a lot of versions of curves, I'll show you some:

I had seen these but they seem a little complicated in my opinion they can do even a little simpler..basta as you say you have some fantasy.. .

bè, but once made a model (I say.. one) others come out for free.
with a model you can get us a variety of diameters corners of curve and rays.
the parametric cad is such precisely for this peculiarity.
 
I tried to make a curve like that of the video, but something strange happens to me, if I need a dn150 I try to set the diameter and gives me a mistake, I don't understand what... I send you the file

I tried to make the development with a diameter of 168.3 and a circumference of 522.39 mm comes, according to you it is right for a thickness of 2 mm it seems to me little circumference. .

you used a k factor of about 0.5, approximately there you are near.
for pieces with bending radius above 100 mm I always try to make a prototype with factor k=1, the calandro and I see that diameter comes out, if it is larger I add the shot.

Excuse me, ehh! But did you draw a curve with ø 20 mm and radius 20 mm??? ? ?
What do you need to draw a pz with those measures?

I also have a lot to say about how you designed the curve, but now I don't have time... As soon as I find a moment, I'll put you a less messed up alternative.
I tried to make the development with a diameter of 168.3 and a circumference of 522.39 mm comes, according to you it is right for a thickness of 2 mm it seems to me little circumference. .
the development of the calandrate sheets (you do only that you should know better than me!) is calculated on the ø medlio, in your case (168.3- once the thickness)x 3.1416= 522,44808 (I considered a thickness do 2 mm), moreover you still have to remove "air" that you gave him in extruding the tube: for this reason I avoid giving it this air in degrees but I prefer to put a linear quota, for example 0.1 mm.
practically the sw gives me this info: tube ø 168.3 mm with thickness 2 mm and a cut in the 0.1 mm joint has a development of 522.34 mm.
I always imposed 0.5 of fk and until now I had no problem.
calculate this: with fk to 1 you have a development that stretches over 6 mm on a diameter of 168.3 compared to a fk to 0.5 ... is not little
 
mike the curve made it following the guide of the video, I never did it with sw then the diameter 20 and radius 20 was a test, I tried to open the file you sent me but as usual does not open it...

If you don't solve the problem, I can't do anything.
 
Some of you can show me how to make a curve like the one that made mike, I can't open it because this version sp0 instead mike has sp3...
Thank you in advance.. .

I arrive (with the help of mike:wink:) and I still make you + confusion. look at the attached videos, I created a welding section with the pipe already opened in a point of 0.1 and at this point you make a normal structural member and add the function of sheet metal.

Good king. the one with the structural elements showed it in the tube ad y, but the disciple does not catch.... :biggrin:
I didn't really use the open profile to not mess it up beyond... often in my work I create profiles to use to extrude various sheet metal... :finger:

in my opinion to make the 90° curve of all sizes is more effective your method, with 2 clicks you have the developments in hand.
when instead you have to make pipes in the space a little complex the method of the already open welded is practical and allows to orient already the junction that could act as an indicator for the orientation (it is a method that already used for time and in production is very appreciated.
