Hi Lee.

I've not come across any of the 'usual' booleans in Atom - I think you would need to buy the next option up, to get that functionality.

Martin.

Thanks to everyone for providing the solution - special mention to Lee for being first with the answer.

I didn't think to swap those two options because I can't remember changing them in the first place, but maybe I did that inadvertently.

I'll keep playing.

Thanks.

Martin.

I downloaded Atom and have been having a play.

I couldn't make any progress beyond drawing circles and other shapes for quite a while, which was frustrating, but eventually I realised that once you have completed a sketch in Atom, you need to apply some kind of Boss or Cut function, and from what I can presently tell, that function will act on all geometry within that particular sketch. I think this is why keeping a sketch simple is important and you probably shouldn't include geometry that isn't needed at that point.

Anyway, I made a video of where I keep getting stuck on Nigel's cylinder cover - it's the extruded rectangle that's used to slice off part of the flange that throws an error message for some reason. I can't think what I'm doing differently, because previously it just seemed to work.

A Cylinder Cover.

Martin.

It's no good. I'm downloading Atom just to see how hard it is to get my head around.

Buy your Wyvern a big box of chocolates and share them together.

If you won't accept help, then you are beyond help.

At this point, what do you suggest that someone could say to you, that will help you move forward?

Martin.

I thought he was using plastic soil pipe for the enclosure.

Martin.

Dave.

Is the plastic pipe up to the job of not collapsing in on itself under high vacuum?

Martin.

Nicely done, Ady1.

I think I'd be using Kunifer brake pipe (or similar), to keep it more compact, it's easier to bend too.

There are no special tools to do this in MoI, just draw the line and Sweep the profile.

Notice how there's no need to position the profile on the rail - as long as the profile is outside the bounding box of the rail, then MoI will assume you want it rotated & centred along the rail. If you position the profile yourself, then it will be swept accordingly.

By adding Points to the curve, you can see that it's possible to create more complex shapes - the generated solid can be updated by moving the Points, or even by updating the diameter of the profile.

Isn't it just a matter of starting a line/curve in one view (say Front) and then continuing into Top and the Left view etc, until you have the shape you need, then finishing with a Sweep to make the solid?

Martin.

Dave.

What made it difficult to do?

Something like this?

Martin.

Can I remind you that there are about 365.25 days in the year to eat Twix bars?

David Jupp has made it very clear that he is willing to 'waste' his time on you. Has it occured to you that this constant back and forth is 'wasting' the time of those on here offering their help?

If you accept David's offer and you make no progress, then you will have been proved correct in your stated belief that you can not learn Atom and you'll both have lost an hour of your lives. On the other hand, if David can move you on a little, then that is progress, but you first have to accept his offer.

As I said before, stop procrastinating by telling us what you can't do and grab the best chance you're ever going to get to show us what you can do.

Martin.

Nigel.

We know you are finding it difficult to learn 3d CAD.

You have two weeks left on your trial of Atom, so I suggest you stop contemplating, swallow your pride at your lack of progress and grab David Jupp's offer with both hands and see if he can help. Don't procrastinate - investigate!

Martin.

A video of nothing in particular - just doodling some Offsets to lines and solids, which add features that might otherwise take a while to do.

The size of the jump in the graph seems to indicate you had a 'Full English' for breakfast.
