Clymbing the learning curve

Fonzis — Thu, 28 Jul 2016 15:09:39 GMT

Good day to everybody

Hi @Anonymous

I am back in Inventor coming from this bad gone experiment in fusion 360 where i have try to find a fast solution. To make readers know.... i wanted to avoid remake a work that has revealed to be anyway necessary be remade from scratch if i wanna obtain that perfect continuity i look for. After @PhiProcarioJr 's suggestions, and the intervention of @Anonymous, here i am, climbyng the learning curve to expand my know how and come more near to the professional 3d creation methods i look for.

I gonna use this discussion to ask my questions when i will encounter difficultys in my learning steps, specially then when it will become harder to find specific answers on some functions that are not mentioned or listed in conventional information manuals or webinars

I think the best as first, is start answering to JDMather, going on from his intervention
---------------------------------------------------------------------------------------------------------

"Having followed your progress - I suspect that you are looking for an "Easy Button" solution.

Keep in mind that Inventor is a professional tool and deserves (requires?) a professional level of preparation.

If I were walking through this with you, I would -

1. set aside this immediate project for about 6 months (maybe longer)

2. concentrate on basic 2D and 3D parametric sketching

3. concentrate on basic (robust) parametric solids modeling

4. move into parametric surface modeling

5. look at the Form tools (T-splines) in Inventor.

I assume you also want to manufacture this (injection molding?) so perhaps a bit of time in the Inventor Tooling environment.

(should keep the Design for Manufacturability in mind right from the first feature)"

---------------------------------------------------------------------------------------------------------

Yes you are right, i was looking for the easy button way, but i realized it, is not possible have a drunken wife whyle the wiskey bottle still is full 🙂

I see that now yes, i am learning tru webinars and i feel a lot more secure and all seems more stable, i am also discoveryng the importance of referenced parametrics and that the tools have so many possibilitys.Forget something can only be own fault and not software fault like it often happened to me in the last times as i was in Fusion or am in acad.

1. Project is set aside, will be just used as mesh for experimental purpose. New will be made here.

2. Parametric in 2d sketch ok this is not hard stuff, 3d parametrics are more tricky, i am learning and atm i am digging exactly in 3d parametrics encountering problems in understanding the behave between planes.

3. You mean simple extrusions from planar sketches 2d? i have learn make extrusions from parametric sketch and sketches on the solid directly. Atm i cant tell you more, just that i love the extrusion tool, so many stuff in it. But i must go deeper. I feel that soon i will need more complicated stuff to be confronted with and learn correctly, because in webinars is very basic.

4. you mean after set parameters use it like the associativity after made the surfaces in acad? I am on webinar, 120 lessons, i am at lesson 30 actually, perhaps is to early and i didnt understand what you mean.

5. Did it already, not big difference to fusion except some functions.

Yes, or mold injection or cnc assembly parts kit. It will depend of the costs: materials and the additive components, resistance to UV and Saltwater, mechanical resistance to rupture at the fixing points of mechanic parts when under load... etc etc.
Or a 3 split mould with different top side for different trigger box mechanisms production without make new molds for each mechanism but only topside of mould that can be changed, or cnc made assembly consisting of 3 to maximal 5 parts (will depend of the propulsion system.

I agree and it is what i try to do, both methods cnc and injection, tryng to respect the Manufacturability together with the needed flexibility for the different versions of accessories and parts that will be possible to mount.

If you would be able to give me some links or info sources that bring me deeper in 3d parametric sketching as basic stuff from webinars it would be great help.
Also explain me better point 4 what you mean, i am sure i did not understand it as i should

Thank you in advance

Start with these videos. (turn on your sound)

Go through the built - ins....

Curtis will be along with some links you should follow....

Then we can start on something simple.

Say the Spear for your assembly....

Thanks a lot, i am on the way

See you soon

JDMather — Thu, 28 Jul 2016 15:48:47 GMT

I forgot to mention - any information you find on 3D Sketching (which you are not ready for yet) is almost certainly wrong (IMO).

So don't get suckered into developing bad habits.

Hi a.risole,

I only skimmed this discussion for now and will have to come back and read it again, but have a look at the link above, and then you'll see that Inventor likes a nice simple wine most of the time.

I hope this helps.
Best of luck to you in all of your Inventor pursuits,
Curtis

Bad habits you say it, but this is one of the most hardest things to understand if is a good one or a bad one when you dont know where you are at and you dont know of what keep fingers away...
I have start watch your videos, already the first minutes have give me more informations about relevant and necessary things that was unclear to me before.
Learning by using serious and competent informacion sources like i am becoming, will keep the illness of bad habits far in future.
The spear is ok i have 2 innovative systems, perfect to start exercising.

Hi Curtis, i thank you very much for your attention

Unfortuntely all the wine in a range of 5 km turned into Vinegar, its the curse of that project
I saved the bible link you gave me, its exayctly what is needed now for a serious exorcism

Thank you again, i am happy to know have available people like you around there

I hope your true meaning was simply lost in translation.

yikes, I was worried there for a second that the Italians thought I was disposable and were going to send me to "sleep with the fishes" or something.

Re: Clymbing the learning curve

Fonzis — Thu, 28 Jul 2016 20:05:02 GMT

I talk 5 languages, this time i have think in italian:

grazie di nuovo, sono contento di sapere che c è gente disponibile come te nei paraggi

lol no no, but it has something, in calabria where i come from you must only worry when a stranger brings some of it to your home, it means someone of your family is sleeping with them. i recommend you to give me good informations hahahah

I started read in the link, unbeliavable the stuff i missed in all this years i must recuperate a lot to be up to date...

Hi all,

operation successful, patient alive 🙂

http://a360.co/2ajy3MS

The first steps was easy, i encountered only problems as i wanted revolve along the construction line that i made as middle line, he refused give me solid in all ways keeping say he need closed profile, i sayd ok then i go to the concurrence, my old friend Loft command. The construction lines helped place all together there where i wanted, the rule of no eat, no sleep if no put constrains is more as right, because it means do 1 time the job and can unleash creativity without care anymore of precision. The fact to not overcostrain or do such things as fillets in the sketch if not needed, was also good to understand how start sketching in a logic and productive way.
For the rest all went ok, now it becomes warmer, i must make first assembly because the flopper is another part..

For some reason I cannot download the file from A360.

Can you attach it directly here?

Re: Clymbing the learning curve

Fonzis — Sat, 30 Jul 2016 11:36:45 GMT

Sure but how?

Re: Clymbing the learning curve

i apologize for my ignorance

Re: Clymbing the learning curve

JDMather — Sat, 30 Jul 2016 12:31:39 GMT

Start a new part file.

Create the sketch exactly as shown below.

(Use the Rectangle tool. Right click on the horizontal line at the origin and change to Centerline. Add the Ø7.5 diametral dimension.)

To the left side of the rectangle - add these two lines and 3 dimensions as shown.

Exit sketching mode and save the file.

Re: Clymbing the learning curve

JDMather — Sat, 30 Jul 2016 12:37:56 GMT

Right click on Sketch1 in the browser and unselect Dimension Visibility. This will clean up the screen for Sketch2.

Start a new Sketch on the XY plane.

Project Geometry the point on the rectangle shown (I project only the geometry that I need).

Re: Clymbing the learning curve

JDMather — Sat, 30 Jul 2016 12:46:46 GMT

In Sketch2 add the Rectangle dimensioned as shown.

Finish Sketch2 by adding the two circles with the dimensions shown.

Re: Clymbing the learning curve

JDMather — Sat, 30 Jul 2016 12:55:21 GMT

Drag the red End of Part marker above Sketch2.

We can move back and forth through history by dragging the red EOP marker.

Revolve the appropriate selected contour of Sketch1.

Drag the red EOP below Sketch2 and Extrude-Cut through all Symmetrically the Rectangle and two Circles.
