Learning & Understand the marks on FUSION360 exercices

[Anonymous]

Hi all !

I'm starting using FUsion360 for my own project using a Prusa MK3 printer.

Well this tool is incredible !

Here are my questions if someone can help me.

* What are the best way to start with Fusion360 and learn step by step.  My intention are to use it for 3D printing only.  I'm ready to pay for video tutorials or so.  I have followed some tutorial on Youtube and can sketch and use conception basically.

* I found a book with exercices to be able to learn sketching and modelizing but I don't often understand the marks on the exercices. (see attachement)  Is anyone can hemp me on how I can understand toe marks to be able to calculate the distances and so for my sketches ?  In this example how can I calculate the total length of the piece and the height ?

I understand R is the rounded percentage

0 is the diameter or the circle 

here I don't understand how to make the design to be able to calculate the right space between the top of the big circle and the edge of the piece.

Thank you !

On a good drawing - you never need to calculate ANYTHING.

Simply sketch with the dimensions given and the total length and height of the piece will work itself out.

Can you File>Export your *.f3d file to your local drive and then Attach it here to a Reply?

Sorry double posts 🙂

Thank for your quick reply !

Well it's more to understand how can I draw this piece in the right way so I look like this piece.

Right now I have 4 circles whohc is great but  I can't see how to make the curve and the space needed between the edge of the big circle and the edge of the piece.

Any tip on this piece on how you would design it ? (using rectangle, circle, etc) so it can be like the idea of it ?

here my piece at the moment

Attach your *.f3d file with the 4 circles here.

Hi, it's attached on the previous post TheCadWhisperer

Thank you !

I will be back in a  few minutes with a video.

@TheCADWhisperer  I'm racing you. Your previous message was eight minutes old when I started recording my screencast. It's eleven minutes long and is uploading now.

I experienced a weird issue that I could not sketch a horizontal line while Screencast was recording???

I had to go to Camtasia to record.

It is good that the OP will get a couple of different perspectives.

@TheCADWhisperer  beat me again!

Anyway, here is my video. It is substantially the same, although has several little differences in methodology.

Kind of hard to model with a 🖱 in one 🖐 and a 🍵 in the other 👈 and a 🍩 between your 👄.

Thank you again !

Just watched the video and learned a lot about sketches constraints.

I already used mirroring in sketches, I saw you made it after.

Is there any advantages of extruding both part of the design (once up and once down of 10mm) instead of extruding 20mm up ?

@TheCADWhisperer Thank you too ! it's not the same methodology but I learned too ! 🙂

Mirroring a Body after the fact supposedly uses less computational resources. Plus it saves your sketches having to be more complex. But there are times to mirror in a sketch...for example when the entire desired result is not symmetrical, but some feature is.

No advantage. You could have just as easily extruded the whole thing 20mm in a single direction, and then extrude/cut the counter-bore 10mm out of the whole thing. I just felt that doing it the way I did might be helpful for your visual understanding while you watched it.
