modeling in the environment together

[mtvonno]

I have to model pipes within a set and as I have to move into space, I was looking for an immediate way of modeling that allows me to take as reference already existing elements in the overall, to draw them a curve and create the solid that begins and ends perfectly aligned with the already shaped references. to understand, I have to connect two ends of a tube that are placed in space and with the modeling in the environment part I can not connect them perfectly, being the rigid tube must be perfectly aligned. Can you?

tube in one part?, or tube consisting of curves and segments of different parts? (so a subaxieme).

pipe built from different parts.
then if you can't like me, then tell me how you would.

There are many ways to do that.
the easiest is to create a set that will be the final tube, put the first piece of the path by default and save.
insert it into the main set, activate the tube set and component mountains (also created from scratch), until the end of the path.
the skill lies in not taking definitive references from the main set.
there is also the way to model it through curves for the path, in absolute (i.e. with the coordinate system of the tube superimposed to that of the main assembly, made the trajectory, complete the axieme tube apart.

the first method does not therefore involve a control with a trajectory in the axieme, but of the attempts to model solid parts in order to arrive at the end? a little by chance or there is a construction system so that the joints are perfectly aligned. I'm sorry, but it's my first time finding me with pipes.
Moreover, I see that you also use catia and for that little that I used it with catia v5 it is very convenient to create support geometries on the together and then model the components directly in the axieme taking as reference the support geometry. It is from the use of catia in this way that I wondered if even in creo could be.

no "in case", models in combination then in top-down, it is clear that if you want a pipe consisting of elements (solded or glued does not matter), you will need a distinct after, which hardly previews measures not whole (at the most they will contemplate the half millimeter); In this case, approximation can involve problems in the manufacturing phase (especially if the pipe is long), that is why it is advisable to control the individual elements and not the pipe in its completeness.

if you mean a method that predicts a trajectory with "n" decimal figures as precision and then coated with elements or with a feature, you can do well.

if again, you want to give a start point and one end and you want the system to preview a path that integrates with "check point" of control to command it, and then to cover it with preloaded libraries that is "bread" for the piping module that obviously is paid aside.

whether you use a cad or another, the roads are all accessible; with catia you create a "gemetrical set" with curves in 3d and then with a body dedicated the cladding, but catia is not at all sympathetic with external references you lose the connection (not that the others are "happy" to lose external references, but it catches on this rhyme a lot against).

but the thing you have to ask yourself is another, that is: how do I want to handle it beyond the mere modeling?; because every road has its pros and cons in this case.
