[inventor beginner] remove solid from another solid

[mir]

Hi.
I am struggling with the bases of the inventor and while knowing discreetly the cad3d I have some problem with the basics to design in inventor. understood the logic of the sketch (and the fantastic functionality of the parameters) I find myself unable to solve simple problems like the one attached.

I created a mouthpiece and I would like to take away the pin that crosses it to create a hole passing the mouth itself.... but how do I do?!? ! !


Thank you.

in the bushing you have to use the working plan command, then select the plan you made visible and then the circular face at the top of the bushing. you will appear a new work plan parallel to the first and tangent to the circular face. create them over a new sketch, use the point command and quote it so that it is in the position of the center of the hole. Get out of the sketch and use the hole command. at this point impose the diameter and as termination select all faces. the passing hole is made.
Hi.

You should use the hole command or, if you want to do it with an extrusion (as I think you did) in the command window you must specify it as "negative" by acting on the coloured icons more or less in the middle of the extrusion window itself.

hole or extrusion (negative). No need to create a new plan. You must directly wax a new sketch on the superore face of the pin you want to eliminate.
then draw a circle of the same circumference of the pin (so that it is superimposed). Shut up. extrusion, with cutting option. set the length of the pin in the length of the extrusion. and you should have done it.

It depends. by the method you describe you definitely have to create a plan, otherwise I sketch it as you do on a curved surface?
the only case in which you do not have to create the bribe plan is if you create the sketch in an existing plan that passes through the section to be removed, otherwise you are obliged.

the upper (or lower) face of the cylinder is not curved but already has its own plane. Just create a sketch on it.

or at most use the visible plan in the center and make an extrusion "cut" in both directions.

I think you haven't seen his pdf attachment. . .

See. Sorry, isn't that a plan in the middle of the highlighted piece?

 

[mir]

the solution of the Ilario is great (it must not have even seen it) ... in fact I also tried with hole but I could not identify the surface of the cylinder ... and I could not create a tangent plan to a specific point.

If you want to make a hole is not the best solution, if you want to do a negative extrusion depends on the cases... for that I said, I know that it is feasible, but it is better, in my opinion, to make the plan tangent and to leave from there... then you evaluate case by case and in the specific case I would do the plan tangent.

 

[Daniele_69]

I agree with the Ilario. in the first answer I started from the tangent plan.

Yes, I had taken it for granted because seeing the pdf I thought it had already managed to create a tangent plan (but seeing it I was probably wrong), but I did not comment your answer because it did not turn:smile:

I apologized but I tried to create a tangent plan... but I couldn't do it without having to create another sketch... so I thought it was more agile to create an extrusion (perhaps because more directed to the subtraction of solids like cad )

se vuoi fare un foro

If, in the model, a hole and a negative extrusion of a circle can generate the same result, when you go to make the table you will have two processing with different characteristics that could create difficulties in the quotation.
as in all cad 3d, things you can do in so many wrong ways and one just right, the problem is that you find out after which it was.

Bye.

I didn't know if you were right or not, I was basically what I meant for this kind of experience.

-> select the plan which will then be parallel to the tangent plane that you will create -> select the curved face to which the plan will be tangent. :wink:

p.s.: do the basic inventor tutorials and you will see that they will come back very useful. (menu "?" and there somewhere you will find the voice "exercises"

 

[Daniele_69]

I am of the idea that a hole should be done with the hole command, while a processing for removal of material (also circular form) should be done with the extrusion command.
in addition to the tutorial, I recommend the " animations show" > parts - working geometry > work plan.

 

[Daniele_69]

for the tangent plane and parallel to a face/plane look here:http://wikihelp.autodesk.com/invent...66_work_planeanimatio/1773tangentandfaceparal

and why, the hole is not a workmanship with material removal?

 

[Daniele_69]

Okay, you're right about that. then let's say that if I use the drill I make a hole, if I use a milling machine I do an extrusion.
