swept variable on the right path

I found the license "home license" that activates some forms, I forgot because in production I never use it.

However, the workflow is identical:

in nx, to do what you ask, you have to use a certain type of surface and not what improperly has been defined sweep (in creo it is called blend, in sw loft and in nx there is the command through curves that does this thing).
I noticed that with creo and with if the command is 'integrated', that is, they create sections during the execution. with sw, instead, you create the sections before (as with nx).
This means, in my opinion, advantages as it allows you to do other things (see film 2).

Yes, in fact, in my opinion, the working method of creo is wrong, and I also prefer to draw sketches first as an autonomous entity, and then select them within the sweep command (if you can work both as a nx and as a creo, at your choice): The reason is, if the sections to be traced are many and complex, such as a wing profile, you risk having to work an hour and more to draw the sketches without being able to save the work done, so maybe at the 30th sketch you wrap up or crash the software, and you lose all the work done until then.

This means, in my opinion, advantages as it allows you to do other things (see film 2).

This I think you can do even in creo and if, that is, edit the feature to add plans and sketches to cross. I don't know if that procedure would allow you to keep the departure and the arrival perfectly orthogonal to the bases as you show in the video, I guess the two cads would interfere on all sections and not only on the intermediate ones as you do with nx.

what I see in the image is the same command used in your first post? because I see there is a guide and so it would be a sweep on trajectory and not a 'sweep straight'.

Sorry I messed up, but the concept I wanted to explain is that....

do not blaspheme, crashing at the 30th sketch will go your software .

However, in case of crash, the work does not lose it, the generated trail.txt files allow recovery of the session until the last click and keep in mind the feature of the versioned files.

Finally remember that in creo you can use both systems ... this for the famous rumor that it is rigid and has only one way to do things.

Sure? If I didn't understand whistles, Ozzy said otherwise, and that's that in the new versions it's mandatory to draw sketches on the fly.

Now I'll put you on the video

I have never said this hunt, I have placed these two examples on purpose, because in my opinion in these two cases (sweep on straight path and on variabiile path) it is better to make them integrated, otherwise we have to build plans of construction, I have done it especially as an example.. .
in creo always has the two possibilities, or external sketches or internal sketches, it is the user to decide which way to undertake according to his needs, in this case better integrated, in the case of the wing profile I can agree with you.

that you have the integrated sketch or not, even with creo you can define the tangences on the initial or final face, provided that there exists the geometry previously created, as told to hunt in creo you have both possibilities, the exercise however did not contemplate this option, we are in topic thanks.:smile:

You're right, I misunderstood your intervention, but it's about a specific case:

Here is the video:http://www.youtube.com/watch?v=nb3tx9ylkeqas rightly said pat, in most cases the internal management of the sketches is much leaner because you do not need to create the reference plans.

just to point out, you said that in the constant section sweep the sketch you can only do it inside the command.
in both cases, when you did the internal sketch it is then possible to treat it, on the plane level, like any sketch? I mean to have the possibility to rotate the plane in any direction or choose a different plane, for example coincident with a face.
other question: in the example you posted and that more or less we all replicated the middle section you created it on the point of union between line and arch. If you need to put yourself along the arc (or along a spline) can you add reference geometry to the spline or lean to external geometry to accurately define the position of the section?

marco, what I used is a blend function (which can be used in this case because they are sketches made on parallel planes) ... the variable section sweep is another function.
synthesized, the blend and sweep blend also work with external sketches, the variable section sweep only works with internal sketches (which I know).

First question: it is possible, because rightly the plan may not be perpendicular to the trajectory, if instead I want it to coincide with a face clearly also, if the face exists first in the tree of history.

second question: yes the example I did using the existing geometry (end line or end arc in my case) if you wanted to put it on the arc you simply need to create a point or more points to fly inside the function on the path.

yes exact max, the variable section sweep only works with external sketches as instead of drawing the sections (derived trajectories), draw the trajectories (derived sections).

Yes exact max, variable section sweep only works with sketches esterni as instead of drawing the sections (derived trajectories), the trajectories (derived sections) are drawn.

If I were a creo user, I'd start to get confused... :smile:

However, leaving aside the names of the commands with which a bit of confusion has been made, between thread titles and clarifications within the threads themselves, I think I have understood to great lines as in creo sketches are managed in these functions.

Pat wanted to say inside, he's still drawing the christmas chapter:biggrin:
