Help with fusion 360

[Ian Skeldon 2Participant @ianskeldon2]

Hi,

I have completed a drawing with fusion 360 and mostly it went very well. However there are two ordinary plain holes on one of the faces that I wish to extend (imagine a U) so that the hole becomes a slot up to the adjacent face.

I just cannot get it to work, I will upload the image (STEP) for gurus to take a look. Also I have very limited options for exporting the drawing and cannot get it to export as a 'STL' file, is this normal and if so how can I print it off?

Many thanks,

Ian

Ahh slight problem, I can't upload image as it isn't in jpeg format.

can’t finish a part off.

If you do a sketch, two lines joining the holes top and bottom, and two semi-circles going around the circumference of the holes, and then do push/pull, would that not do what you require ?

Hi Ronan,

I will give it a go, will let you know how it pans out.

Thanks for the suggestion.

For us to see a picture of what you are drawing, you could do a "Print Screen" and save that as a JPEG. In the absence of that my approach would be to draw a rectangle representing the plan view of the slot on the adjacent surface and press/pull that down to the diameter of the hole.

To save as STL, right click on the drawing title at the top of the drawing menu and select save as STL about half way down.

HTH,

Rod

Draw a circle where the hole is, add two tangental lines and a third across the top

Trim out the top half of the circle to leave the outline of the shape you want to remove

Then Extrude-cut out the shape you have just drawn

I think you should be able to share the F-360 drawing buy clicking File then Share, try this link for my sketch above. If you share your drawing and then open the link yourself it can be downloaded as an STL file and quite a few more than if you just use Export

Many thanks both Rod and Jason,

I haven't had the time to try anything yet but I can already see that I made the mistake of adding a hole, rather than drawing a circle….Doh.

I will follow this up once I have had the chance to try the suggestions.

Once again many thanks for the help.

While having a quick play tonight I discovered 'SLOT ' what a muppet !

I simply drew a slot to the required dimension and even though the top half of it was in free space, I went on to extrude with a negative figure and bingo, worked straight away.

Anyway many thanks for offering help chaps, I now have several ways to achieve what I was after.

I just cannot get it to work…

Word of comfort to Fusion beginners, at first I had similar mysterious problems with stuff that didn't work as expected. At one point I thought the software was faulty and/or stupid.

The problem was me. Early on my understanding of how to drive Fusion was hazy and often plain wrong. My mental model was flawed and I was forcing Fusion to match my view rather than letting the tool do the work. (This is particularly likely to happen if you already know another 3D package and have it firmly fixed in your bonehead as the one and only correct way to do business. It's not – you are wrong!)

Though Fusion is logical, it is possible to create internally inconsistent 3D models. These look OK on screen but cannot exist in the real world due to their impossible geometry. Sooner or later asking Fusion to change a flawed model fails because the operation makes no sense to the model. Simple edits that don't work as expected often indicate an earlier mistake.

What you see on screen isn't the model, it's but one representation of the 3D objects, themselves nothing but numbers, that represent your design. There are various other views of the model where Fusion indicates concerns; it doesn't list them for you in one place. However, quite a few inconsistencies show up on the edit timeline at screen bottom. Make sure the timeline has no steps highlighted in yellow(warning). Although Fusion is good at correcting early structural errors, it may be necessary to start again. Another newbie mistake is to persist with models riddled with mistooks. Sometimes it pays learners to start again.

The good news is that learning Fusion is rather like learning to ride a bicycle. Once you've tuned in to how it works, it becomes intuitive and you're off. Now I've got used to Fusion, it's hard to replicate the issues that baffled me so much when I started.

Keep practising. The more you use it the easier it gets.

A situation that is certainly not unique to Fusion! I spent ages trying to clip a cylindrical hole out of a large rounded part without success, until I eventually realised my solid part was actually an open-ended shell of zero thickness!

This is what I was trying to achieve, it seems so simple now I have done it. Thanks to everyone for the help and encouragement.
