Bye to all,
as mentioned in the presentation, for the major I used solidworks to design. in that cad I created a part that kept the different sketches to make the project skeleton (mainly were the 3 floors, the origin and a 3d sketch).
I’m following several videos but you know, top-down design is always a painful point to touch. . .
I want to know:
Is there 3d sketches? I mean, how do I do a sketch like this?

good morning, in creo there is the skeleton that e5 a special part that encloses the reports of a x set design in top down. you can do whatever you want, planes, axes, csys, surfaces or solids. in the specific case you have to make a curve that equals your 3d sketch of solidworks.

Hello and thank you for the answer.
I take advantage again, to understand how you work on creo unlike how I worked on the sw.
I tracked all the lines and points in my sketch and then gave it the odds. after which I used them to anchor plans and axes. In this way I had a complete picture of the skeleton in a sketch (if I hid plans and axes) and all the "parameters" to bind the various parts. I create, therefore, straight segments, I feel like I can't do them right? Can I just bend?

Hi.
what you posted as an image you can do in different ways.
create points in space and then tie them with curves through points(2 points at a time othermeti becomes a curve that passes you for the points you defined but not composed of straight lines)
then, if you need it, make a copy of the curves and get the 3d curve.
or
You make lines sketches up, and then, if you need it, make a copy of the lines and get the 3d curve.

with I create you will do everything you did before but you will probably have to use a different method.

 

[Max-C]

I'm convinced. there will be things that I will put more twmpo to do or use more functions and others that I will do more smoothly. I am well aware of this.
Thank you very much

ciao @max-c , as they told you above there are more methods to get the result you want, I personally would opt for the composition of more sketches enclosed in the axieme that will give you the "skeleton" with all the necessary positions, as well as serve as support for plans and anchor points.
considering the sketch you show in your question you can:

1 - place on the top floor and make a sketch of the three lines 15 - 240 - 15,
2 - create a reference plan parallel to the right floor (or you have called the top orthogonal plan and which is crossed along the direction of the 240 line) and coincides with the 15 line,
3 - realize a new sketch with the two lines 15 - 135 taking as reference the final point of the previous line length 15,
4 - mirror this sketch from the opposite side or repeat the operation if the two sides are not symmetrical.

I don't know if I interpreted your intention.
if instead you need a skeleton that allows you to cinematic movements things change (personally I have never done it ;-))

Thank you very much.
my intention is to understand how to reason with creo and if there are points in common with sw. the mobile skeleton never used it even with sw. I always used a skeleton only with axes, plans and sketches to give me the origins and bound the parts to that. then (called brutally) dragging the component (for example by turning a gear) I saw how the other organs behaved.

with I create I see that if the movements are simple (for example 2 gears with ratio 1:1) I can do the same thing I did with sw. but (and here correct me if I'm wrong) if I have 2 gear with ratio 1:2 I have to switch to gear couplings and then to the right kinematic module?

Good afternoon @max-c , in reality with creo there is a special set of constraints to do what you want to do, you use instead of the classic constraints and you can give maximum and minimum position for the various components and relative movements. other software do something more immediate, since they have only one set of constraints and the components move dynamically if free in some movement and moved in by simple moves.

in creo you can convert costrains (classical vines) into connection (dynamic vines) which as indicated by @shotfree allows you to give restrictions on travel, both liner and angle, and default positions.
