Dear Mr Gibson,
I tried your method, but nothing happened. The selected inner cylinder still does not move after I follow your instructions. To accomplish this, you must modify the command move. I would appreciate it if you could explain it ?. 3Dmoi has a lot of good features integrated in it, but sometimes I'm not sure how to use them. It would be great if 3Dmoi v5 update had something that would amaze me for my work and you could tell us what you are changing or what new commands you are adding. Thank you so much for your support.

Hi Ray, that's a preview of something that will be new in the next v5 beta release.
I'm almost ready to release it, just a bit more tuning.

this is all really exciting and endlessly useful. Any chance to have a "shrinkwrap" utility in the future?

Hi beanworks,
re:

Shrinkwrap is very difficult to implement with CAD geometry which MoI is focused on using.
It's more feasible to do with a polygon mesh instead.

Ok, almost ready just 1 or 2 more days.

On the subject shelling, Michael.
Is there a way to retain the part that is cut out and discarded from an internal shell action? I'm thinking that Keeping that part might be useful for cores in casting work.
It looks like you've made a good move by integrating ACIS into MoI and I'm looking forward to updating to V5 once you're happy with it.
Many thanks.
Martin.

Hi Martin,

If you want to generate a solid for the inner void, that should be possible either by using the Offset command instead of Shell, or you can also convert a result from Shell with an inner void and convert it into 2 solids by selecting it and then use Edit > Separate to break it into individual surfaces followed by Edit > Join.
Join does not try to generate inner void cavities.
To go back the other way if you have 2 solids and you want one to be a void cavity, you can use Boolean difference to make that. Select the outer solid as the base object and the inner one as the cutting object.

Rotation hooked up now too.
It is fitting in seamlessly, no new commands or even any new UI needed!

Nice, I was secretly hoping for this, but I didn't want to put pressure :) ... super handy for shape exploration !

Very nice indeed!

The new tool is extremely useful. The way it fits in the current toolset...beautiful.
From: Michael Gibson
Ok, building new beta release now.

New Sep-17-2025 v5 beta version now available at
https://moi3d.com/beta.htm
Will be working on full release notes a bit later, there are more functions integrated from the ACIS geometry kernel.
Selected faces can now be manipulated with the Transform > Move, Transform > Rotate and Transform > Rotate Axis
commands. This uses the ACIS direct model editing component to extend and intersect surrounding faces to
accommodate the change.
Enables dynamic editing of solids like this:
New RemoveAndFill command - use Shift+Delete keyboard shortcut or Shift+click or right click on Delete button to invoke ACIS Remove component that deletes faces and then heals the resulting openings by extending and intersecting surrounding faces:
ACIS Shell function is now used by the MoI Construct > Offset > Shell command.
Also lots of fixes for ACIS filleting.

Very cool, thanks Michael. Going to install it right away.

Hi Michael.
Thanks for the advice on using the Offset tool - it worked beautifully.
With the new Delete Face tool I'm able to discard any superfluous parts to get the cores as I want them.
All the new features are working great with only the occasional 'phantom surface' when I Shell fairly complex parts. I could send a file if you need one.
As I only have a slow laptop, I can get a significant lag when using the new Move Face tool as MoI updates whilst trying to keep up with mouse movement, so I wondered if the live update could somehow be suspended until Moi had locked onto an intersection point or maybe turned off if necessary?
Thanks again.
Martin.
