multisection command

[marcoevolution]

I have to use the multisection command but catia warns me that the spline I created is not closed: to be able to close it (under a screen of the situation) I tried in all the ways I know:
1)concidence between the control point and the sketch I created
2) Command position point with coordinates (playing on the tenths of millimeter)
3)Inflating the casket to see if it coincided with my needs
wandering the internet I read that it is possible to overlay two points: did I mean wrong? How can you do that?
thanks in advance

Hello, Marco.

I imagine you are working with solids in part design (otherwise with shape design surfaces spline in multisection you can also use open. . . )

I also imagine that you created the spline in the sketch and then try to close it in 3d environment...

if you have created the spline in the sketch, it is in the same sketch that you have to close it, otherwise then it recognizes them as unified curves (and you should join them but you can only do it in shape environment)

falls into the sketch and generates the closing geometry (using simply the snap), to be sure that the menu/instruments/state analysis is closed: closed.

when you exit the geometry created in the sketch will be considered closed.

Let me know.

I don't do as you perfectly described: what I can't get is the result that I hope because I am joining thorns and sketches without mesh points that I can use for contact with snap

 

[marcoevolution]

Here's the situation

 

[gianni55]

if the entities I see are all in the same sketch should not happen, or better when you create the line, the snap should recognize the final point of the entity already generated and hook the first point of the line (coloring orange the entity and viewing a blue circle and identifying the point filling it with blue)

Let me know.

Excuse me, but for multisection, you don't need 3 sketches? ?
1st for the first geometry
2nd for other geometry
3rd for lòa spline
screen plan is that (spline sketch) of spline design

 

[gianni55]

the entities to close the spline must be all in the same sketch... At first you wrote that the spline you created is not closed, I'm answering you to close the spline, although it seems to me that it's not what you need.

Tell me:

1) is the first geometry closed? (and is the first section)
2) is the second geometry closed? (and is the second section)
3) the spline sketch will you use it as a guide curve?

If so, to create the spline that you will use as a guide curve you have to use points that coincide with the sections, to do this you have to project the point into the sketch ( icon on the top right in your screen), careful to use the construction mode for the point and standard for the spline

Let me know.

I wrote to this forum because I am a student, I have no experience with parametric software (catea is my first interface with this world) and I was asked (though with gross approximations) to design a solid model of an airplane
now
who wants to help me is always well accepted but no one is obliged to do so: therefore respect and patience
but unfortunately I did not understand the procedure that explained to me: Finding me in the spline sketch, if I go to click "project element in 3d" does not make me select the control points of the spline, but I can select only the profiles (shown in orthogonal view on their drawing plan) which as it says are colored in orange and from there I can move with the spline in standard mode, while with the profiles of the sketches in construction mode...but to what I understood it is not the procedure
after a couple of attempts at zonzonzo I managed to bind it graphically but nevertheless it signals that the profile is not closed: Can someone help me by describing a procedure for simple steps by specifying where I have to start (environment 3d or what sketch 2d? )
thanks to all

This is another angle

so, only by curiosity (but considering the fact that I responded only to you), in which my sentence you saw lack of respect and/or little patience?

among other things just to help you better I sent you a private message proposing to use skype (not receiving any response)

All right, let's go ahead: project element in 3d should not be applied on the spline, but on the profiles... Now that you have sent a more understandable image, I see that the profiles are closed, so you have to use intersection 3d elements.

Step by step:

enter the sketch
Construction
intersection 3d
selections first profile
create the intersected point
intersection 3d
selections according to profile
create the intersected point
standard mode
create the spline: first point of the spline, the first intersected point (which will be recognized by the snap), intermediate points, last point of the spline the second intersected point (which will be recognized by the snap)

the spline used as a guide curve should not be closed, but must intersect the profiles.

Let me know.

It worked! !

to find me to do things (although of my interest) to me unknown without explanations that satisfy me and that therefore lead me to look for "traverse streets" in order to be able to find information that I consider essential for the success of the tasks that are assigned to me... since I take the role of the designer very seriously (aspiro to do this one day) is frustrated for me to have to "put the face" with problems, find it wrong Your private message I haven't even seen so much that I was focused on caia, video tutorials on you tube etc.... (check if you care and don't believe me). All this doesn't want and shouldn't be an excuse: my behavior was unacceptable to a person who sincerely tried to help me...I apologize and believe me when I tell you that I'm really bitter about how I responded
