developable helical sheet (helical slide)

[REDS]

Hi, guys, this is me. I'm red paolo (yes... it's my real name... ) and project machines for agriculture with proengineer wildfire 4....
but I used previously inventor, solidedge, catia v5...and now...unfortunately. ..proe...

I have a problem.... I have to make a sheet (helical slip) that is somehow developable. I managed to achieve it with the surfaces, but I can't convert it into something developable. Can someone give me a hand? I attach a jpg where you can see the sheet in question (the lower part of the cylindrical part)

Thank you.

this is the desired shape...but I can't develop it... someone who can give me some tips? Thank you.

(Parliament adopted the legislative resolution) googular a little and look what features must have a surface to be developable.

Hi.

you can try to copy the lower or upper surface of the sheet in question and use the command
- merge surfaces under the surface menu
that is to select the surface, the starting point for the sanding (also a vertex) and get the development of the surface on the plane.
I'm not sure it's exactly the desired development (previously developing with think 3d, now drawing molds for plastic) but it can be a start.

Hi.
in your first message in our forum you could save it.

...and now...unfortunately... .

Anyway, since today is Friday and I feel like I'm in the mood for advice, I'll give you this straight.
do a search by inserting in the cochlea message, you will find discussions that will probably be useful to you.
Greetings.

I have written unfortunately for the fact that I have known him recently and in some operations it is rather sluggish.... then I highly appreciate the lightness of the management of the assemblies. Unfortunately I looked everywhere on google but if I use helical sweep I can't develop, and I haven't found a solution yet. Thank you all for the straight!!

Hi.
the search you have to do in the special space of our forum, and you will find useful news.

I searched in the forum and found in "splanning a particular piece!" something like that, and it is recommended to use the command "insert/advanced/union flat surfaces", but with my component does not work..... I will be stupid I:-(

 

[DANI-3D]

the piece in question can be realized in two ways:
for deformation, with a mold, in this case you can start from a helical sweep, but it is not possible to develop the sheet on a floor.
by bending, so by doing you have to combine a number of flat surfaces between them, depends on the accuracy you want, by this method, if the part is well built you can have the development of the flat state.

Hi.

you can split the two edges of the propeller with an equal number of points depending on the accuracy you want to get (select the first edge and insert the point with offset 0 for the first point, offset 0.1 for the second point.....). obtained the corresponding points generates a curve passing through the two points, one by side (with a little familiarity you can do it in feature series).
successively generates the limit blend surfaces passing for the curves two to two.
Finally you look at all blend surfing and get the developable surface (I believe).

No. the unspoiled surface union command can also have a sum of distinct surfaces but without edges (if necessary insert a radius of even microscopic connection).

hello reds, try this solution too.
creates a new part, menus "insert",shared data,copy geometry,from the unchecked open command options
"only published geometry" (cubetto con freccine ndr), click on references,in select 1 element open
model from which to copy the geometry,in positioning leaves default,ok, click on surface sets and opens the model
of the cochlea.
select the top surface of the sheet, central mouse key and copied the geometry in the new part.
add a point on the initial edge of the surface, from the menu insert, advanced, union flat surfaces, in
we spy on, union origin surfaces select the surface, at the origin point select the point you created,
Okay.
easily create the part I attach to you.

Hi.


I realized that in order to use the union command flat surfaces I had (in creo 3) first eliminate from the example the face surface (first wall) from the model tree.

Hi.

a feature of union flat surfaces is a single flat surface, which creates parameterization
after which it stretches it maintaining its characteristics.
for this reason I copied only the upper surface of the coclee and extended it.
if you eliminate only the first wall remains the sweep with the trajpar that you cannot
flatten.

Hello jambo,

I meant that in order to be able to apply "flattened surfaces" you must however proceed with the copy of the surface ....
but in order to activate the command "flattened surfaces" you have to delete from the side the face surface feature (first wall) from the model tree (otherwise the command does not activate me for the sanding operation directly on the test file).

 

[JAMBO1970]

That's why I preferred to create a new part only with geometry
necessary to the quiet state.
