progetto 2stroke engine

[Gnomas]

as from title, I am mobilizing to create in inventor, a project of a 2tempi engine.. .

I want to point out that I am self-taught and that therefore many tricks and various robes do not know them, that is why I come to ask you help!

Now I don't know if any of you are experienced also of engines, I cmq will try to make me better understand:finger:

I have various problems I couldn't solve, like:
1) in creating the headboard, I need to polish in mirror the zone of the blast chamber (it would be a job to do post-production of the piece), but I can only mirror the whole full head instead of mirroring what I need.. .

2) in creating the side beams (they are simple windows that "look" inside the cylinder), I can only create them so that their axis is in line with the horizontal axis of the circumference....while I should make sure that lancino towards the exact center of the cylinder, in any position on the rectangular circumference I put them... I tried with the "face" command but I can only tilt the line that corresponds to the whole window .

3) in creating the discharge, drawing the sketch in the horizontal axis of the cylinder, and then extruding it by cutting it up to the diameter....however being circular, a portion of the extrusion goes also beyond the cylinder, while I would like to succeed in making sure that the extrusion is limited only to the circumference of the cylinder

4) the discharge piece where you will go to insert the muffler I should do it tilted down to the cylinder, while I can only do it perpendicular to its axis....I should therefore tilt the whole face, I think it is similar if not equal to point 2

I hope I've explained so and that someone knows how to help me:biggrin:

I hope I've explained so and that someone knows how to help me:biggrin:

1) in part : click on the area you want to have " mirror" --> button dx --> properties --> choose the "face color style "

3) in the extrusion curtain you have two folders " shape " and " other ", choose this last and check " minimum solution "

2 & 4 ) unclear, I abstain.

Bye.

 

[Gnomas]

Thank you very much, point at 1 ok!:finger:

for the solution to point 3 I cannot select "minimum solution", is transparent and there is no possibility to tick it.. . .

I have another problem:

Is it possible to "duplicate" a sketch? ie I should do an extrusion and an identical at another point of the part, but it turns out difficult to remake the same sketch by hand... is it possible to duplicate it?

edit:
found to duplicate the sketch

"minimum solution " you must select premium to indicate the termination area.
because you do not understand, but so it is.

mi dà questo errore....forse sbaglio qualcosa io ma non riesco a capire:frown:

"the feature as specified did not change the number of faces (and may not have affected the part). accept the feature that resulted, or use edit sketch or edit feature to change the feature definition."

 

[diegus]

I think you should look at the use of the working geometries you find in the guide.

"the feature as specified did not change the number of faces (and may not have affected the part). accept the feature that resulted, or use edit sketch or edit feature to change the feature definition."

The extrusion you did didn't change the solid.
on these occasions it can be useful to attach the file with the problem, so we can evaluate and give you more targeted advice.

Bye.

 

[Gnomas]

I attached the cylinder file.. .

then the unloading would be the one with cross (look at the project, not the photo), divided then into two wounds similar to a triangle....as you see the extrusion continues for a few mm while it would be to limit to the circumference of the cylinder itself. . .

of the side beams (the famous window on the cylinder) I drew only one, and if you set the view from the top of the piece, with the visible hidden lines, it is evident that perpendicular launches regarding the axis of the cylinder, while it should launch towards the center of the circumference....
I have attached a photo in which you understand well what I should get, as you see if you follow the conduit profile to the light on the cylinder, you will notice that they point more or less towards the center of the cylinder

by inventor use the 2009 version

 

[stefanobruno]

I attached the cylinder file.. .

Look, I figured out what you wanted to do.

Bye.

 

[Gnomas]

Thank you so much stefano you did me a perfect job! :finger:

only you have to explain how you can put the radial work plan: I need to do the other travase too and I can't always do it to you!:36_1_13:

for the discharge I think I understand!:biggrin:

 

[stefanobruno]

How do you put the radial work plan

"work plan " --> select the axis y --> select the yz plan.
opens a curtain where you propose the default angle of 90°, perpendicular to what you selected ( yz )--> type the angle you want ( writing the value you will see vary the angle position of the new plane ).
on this plane, radial and angled, trace your sketch.

I am doubtful that your initial settling does not allow you to "change share to creation ".
if so, go to the menu " tools " --> " application options " --> " sketch " --> put the check on " change share to creation ".

another thing, better bind the sketches.
Your lines are almost all substantiated, if you have to change anything you might have problems.

Bye.

 

[Gnomas]

Thank you so much for the help, to better bind you intend to put constraints of position type perpendicular, parallel and similar things? cmq I saw that you modified my sketches, and you also listed the distance of the center of the arches from the axis of the cylinder or similar robe, you mean so?

now I should move from the profile of triangular discharge light, to the actual discharge that is circular d32....super problem since you have to tighten horizontally and widen vertically. What idea?

ah then I think I have changed something in the sketch settings: Now when I make a series of lines in succession it no longer delimits me an area but I have to use the sketch doctor that displays me "open loops" and manually close the area otherwise I can't do any extrusion or revolution work! !

Sorry for the many questions:

Yes, the sketch must change color (with black screen, from cyan to magenta )
when all segments are bound, with quotas or geometric relationships, you can do your work without fear of unwanted changes.

now I should move from the profile of triangular discharge light, to the actual discharge that is circular d32....super problem since you have to tighten horizontally and widen vertically. What idea?

make a "loft" work between two sketches.
on one side the circular section d. 32, on the other an elliptical section with the characteristics that most hold you. (good fun:biggrin: )

boh, I'll get you my setting.

in the sketch, dx key, constraint options, put the check at least on "the accident", then you evaluate the rest. The situation should improve:

 

[Gnomas]

I did the exhaust loft and other small things, now I have as usual other problems:smile:

I wanted to know if there was a way to group the various fittings that you make, for needs I had to make many of them and now I have a list of kilometric processing....

now after the discharge loft I should make a traversine loft, that is what divides the triangular discharge into two symmetric sections: this must go as it advances to tighten up until it becomes 1mm wide rectangular section....I tried again with loft but gives problems
