good morning, I must create a threaded stem m20 240mm long.creo extrusion and then as I execute the threads using curves/helical spiral.pass-pass managed to explain it to me?

Look, the subject has been treated a thousand times. I want to give you the benefit of doubt:wink: why the "search" function in the forum is working as crap and you will not have found ninete despite several attempts with keywords such as "filetto, thread, screw..."

therefore the procedure is:
do the stem of the screw
create the propeller (see in the help) on the stem represents the performance of the thread
do a sketch on a perpendicular plane at the beginning of the propeller (see in the help) that represents the thread profile
make a sweep cut (see in thehelp) using the propeller as path and profile as section
 
already done - you tube teaches.thanks again. I look for other sources because the function looks for the forum not from good results indeed.....
 
I'm sorry, but what do you need, right out of curiosity.
as from attached image, you will notice that 80% of the recalculating time uses it for the sweep.
This is a simple object.
If you use these objects in the assemblies... don't complain for the time of reconstruction.
If you want to look good with a rendering... there are some plots on purpose.
I hope you use it in the environment together with a simplified configuration.

a curiosity about the threaded screw.
I was watching this video:
http://www.youtube.com/watch?v=b0npqkpjddi&feature=fvsra 2:34 creates a triangle to be extruded to simulate the thread.
What I ask is this:
the center of my triangle has only fields for x,y coordinates while the beginning of the thread, to which align the center of the triangle, has x,y and z coordinates
I have to edit in the triangle just the z but how do I do it? ?

that then I tried to move the triangle by hand trying to hook it to the beginning of the filettaura but this is not a remarkable point of hooking and I can not even create a relationship between the center of the triangle and the beginning of the thread.
Why is the report menu off?

apart from thinking in terms of co-ordinax,y,z using swx, it makes me creeps (forgots of autocad, pretend that it is never hesitated) but it seems obvious that you cannot change the co-ordinate z of your triangle since this is linked to the plan on which you built it and that, while changing the sketch you can't move it.
if you did the propeller at the beginning of 0° as in the video its origin coincides with the upper plane. to bring the coincidence triangle if you do not hear the end point of the propeller selects the propeller and the point of the triangle and then sets "perforated".
If it doesn't work, you have something not coincidental.

I add that I have the type that uses swx in that video works like a dog!
Place the triangle at the origin of the propeller by typing the coordinates without putting any constraint! :eek: Plus type the size of the sketches from the fields of the property manager of the entities also without putting a quota. fantastic then see it go to select by hand in the appropriate field the value to be overwritten when this is already selected by default and ready to be overwritten while it would be enough to type the new value.
already that you did us a favor, forget besides autocad also the way to manage the size and positions of the geometry in a parametric cad of that video.

I think you got the whole speech.
the difficulty in learning sw is not so much in building the piece, that at the end you do it.
the point is in doing so according to the logic of development of the program that is quite different.

for example, always the same author, in this video,http://www.youtube.com/watch?v=cbcw3twjpvi&feature=relatedHe builds a nut and at 2:34 I don't understand what he does and how he succeeds.
that is, it builds the sweep inside the vine while being the triangle outside the propeller:
I understand that it succeeds because the function digs in the material and when digging in the vacuum obviously does not cut anything but honestly I tried but I did not succeed.
I have to try tomorrow.
cmq if you have a more "correct" video to build lives and I would like to see it.

There's nothing wrong with that video.
the sweep cut must start from "outside" if not leaves a stretch of propeller
not "worked".
If you can't do that, it's just because your
cutting profile does not match the object to be cut.
for a match, instead of the sweep cut, test with sweep extrusion: you will have
the "solid" helix and you can easily check if the object is interwoven
main.

Would you be so kind to tell me why the sweep doesn't make me do it? ?

the sketch is greater than the step of the screw... increase the step and resolve.
I also strongly recommend you to use quotas, as it is a design at risk
chronic error.
use relationships and what else... more useful than knowing how to fill a built dice... to the eye. .

..and with left thread. .

also you advice hotly to use quotas, as it is a design at risk chronic error.
I guess it's a refuso and you want to write "ti Order to use quotas" :tongue:
before even providing solutions or help imho you have to obligate to remake the listed and bound model as you must.:cool:

You know, I'm too good.
