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 solved it wrong to give him the radius...:biggrin:

I would have bet.... (I did not see the file but I have a good imagination..) :biggrin:

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.
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.

the version you have and 2012.r3?

Guest
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.[youtube]H1 embassy[/youtube]

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.
