sweep 3d

[africagia]

Good morning.
I wanted to get out of curiosity. in case, there is a sweep where the trajectory does not lie only on a plane but in 3d, there is only one command that does this? I attach an image for more clarity! Thank you.

with autocad you were poly3d!

You can do it in two ways. the first is to place appropriate points and the second to use a dedicated module.

first method:
1 place corners or curve points
2 I create the linear segments in pairs between the corners or between the terminals of the curves, obtaining in both cases a continuous line
3 I use the sweep by defining as a trajectory the first tracked curve and making at the moment the definition of the section. In this case, I'll place you an orthogonal plan where you put the origin of the line.

The section can be what you want. the only thing a bit boring in this process is to calculate the exact point for the curves. but you have the creation of many different curves.

the second method instead is to use the efx module that is dedicated just for the kind of work you want to do. in this way you will create so many parts as the pieces that make up the structure.

I would say that if you have to do something a little more important than the design you posted, then the efx module becomes fundamental, even because it manages the joints and what else. If you have to limit yourself to things with a couple of curves, then put a couple of points and you solved.

depends on what you need to draw, if it is a pipe, as in the image you post, you just need the steps and use the pipe command.


If you need to use a section other than a circumference and do not have specialized modules, just draw a reference curve through the points and then use it for a variable section sweep.

or always use the pipe command with "no geometry" option (to track the curve) and then realize the variable section sweep.

Hi.

Thank you. What I care about is the first method. It's just a curiosity that came to me, in the end, in some way, I managed to realize but I used extrusions and revolutions to realize the design posted before. I don't understand one thing in the first method. I realized the 3d curve as you indicated me. now I go in sweep in the definition of the trajectory select the curve realized previously, but then I can not go further, asks me chain: one by one, chain tan, chain curves, chain surface, chain I mean.

Thank you. That's what I was wrong: the variable section sweep. Now I'm trying the pipe command.

It's not that he asks, but you have to choose the type of selection to do. In the example I posted I used one by one. holding ctrl I selected the various curves, click ok and then it makes you draw the section, which can have any shape you want.

but I realized a single curve, so using one to one I selected the only curve, but then it doesn't make me end.
Anyway, I did it with variable section sweeps and pipes.

Excuse me, but the piping command where I find it?

Thank you.

hi maxopus,
I tried the command, it looks like it goes well but I don't see a tube:biggrin:

How come?

[blubossa]

Sorry, I solved...:biggrin:

Hi.

method 3:
drawings on two orthogonal planes (front and side) the two sketches represent the projection of the 3d curve on the planes themselves.
intersect the two curves and get the 3d curve

I usually do 3d sketches, creating plans in the different angles I need. I didn't know the piping function. I'll try!
