Is this fillet possible?

[helin1234]

Hi,

Just wondering if anybody is willing to try this out.

I have this gear lever I'm making as practice and am sort of stuck on one of the fillets.

I know it's not a crucial part, but crucial or not I am practicing so would like to know the answer.

In the diagram, there are two R2 fillets located where the handle meets the shaft.

Can these two fillets be drawn?

I have added my file as well, if anyone would like to let me know where I went wrong. 

Thanks,

Sean

Welcome to the forum!

From what i can make out in the pdf, the edges of the center shaft are also filleted.
In your file you applied chamfers to them, so change those to fillets and you should get closer to what you want.

On a sidenote, your sketches are not fully constrained.

This can cause problems further down the path, so it's usually better to take the effort to fully constrain them.

Hey thank you for the welcome and response! 🙂

I have some follow up questions to your response.

I changed my chamfers to fillets and was able to apply that R2 fillet by the handle! However I was only able to apply 0.7mm as max fillet for the shaft edges. Is this right?

How were you able to make out that the edges of the center shaft are filleted?

I didn't see any markings for them so I went ahead and chamfered them.

I am still quite new to cadding and do not recongnize a lot of these symbols. Like for instance the big check mark with 3.2 (top left). Or the G8 (+0.03  +0.01) (bottom left).

Thanks!

I wouldn't know honestly, i didn't see a dimension for that fillet on the drawing.

Purely visual, in the isometric view the edges look rounded instead of sharp.

Those markings are for manufacturing, the checkmark is surface roughness and the G8 is fit tolerance.
They aren't critical for modelling the part, but when it gets manufactured they are important.

Ahh I see...

Well you have been very helpful,

Thank you very much! 🙂

Missing R6 dimension in Sketch1 and a Tangent constraint.

The holes are the wrong size for M4 tapped threads.
