Modeling question - Using a 3D solid as a sweep tool?

Anonymous — Thu, 29 Mar 2018 13:37:31 GMT

Hi there.

I’m trying to model the machining detail into a cylindrical part.

Basically I need to do a sweep feature, but rather than using a 2D sketch, I need the sweep “tool” to be a 3D shape.

If you skip to 1:38 in this video: https://www.youtube.com/watch?v=o3IQv9mT6JU , that’s very similar to the type of machining I need to model for, but with the tool only going to a certain depth into a solid rod.

I'm (hopefully) attaching a screenshot/explanation, and the part.

Is there a way to do this?

Thanks in advance,

Felix

edit:

(offset, split, then thicken won't work, as the edges of the cut aren't then parallel as they would be in real life)

(standard sweep wont work, as there are no radiuses so the corners go weird)

Welcome to the community!

There is an already accepted idea for this:
https://forums.autodesk.com/t5/inventor-ideas/new-feature-sweep-solid/idi-p/5333169

So i guess it's waiting for it to be implemented.
Hopefully someone else can help with how you could do it now, as i'm at the end of my day.

Thanks for the reply.

That's good to know, but not so good that it was proposed 5 years ago, accepted 3 years ago, and nothing's happened with it yet.

I have now managed to bodge it, but it's a complete mess of a feature tree, if anyone can advise on a better way to do it that'd be great!

Ha ha.. so cute You must be new here..

There is a link at the top of this forum where you can become a beta tester to see new functionality and to have some involvement in that process and to see whats coming in the near future..

It can be done, but the set-up is a bit of work. (But not terribly difficult.)

If I can find the time - I will create solution geometry this weekend.

I would encourage you to join the Beta as mgyvr said. This is something we have been actively working on. It almost made it into 2019 but the quality was not there so we are continuing to improve the algorithm every day. I am personally involved in this project and hope to see its release in the coming year.

Thanks for the help everyone.

I have requested to join the beta, so will report back if/when I get accepted.

Thanks

In which case I won't report back! Thanks.

Hi Felix,

Here is a model for you to have a look at. In IV2018 format. I am sure - there is some room for improvement. But in a meantime - that's all I have got so far. The design presumptions were that the groove is cut with the slot mill cutter and the bar is a solid one. So, the bottom line of the slot in any given section is a straight one.

Best Regards,

Igor.
