Hey Michael - amazing (in theory! ;) ) yeah it's just to troubleshoot quickly / show clients how interiors of objects are looking and faces are a great way to do that to showcase solids...I am having some trouble though - it seems the tool fails quite early, (video didn't catch) but at the end of the slider a slice will appear again but majority of geo is just skipped?

Excited for this though so cheers as always

Hi Rich, that's probably actually a bug in Shell in the current beta. For a shell with an internal void cavity and no openings set the "Library" option in the Shell command options to Library: Solids++ for right now. Or select the top face to make an opening there.

Try with the attached file. (updated Section with cutaway option almost ready).

Instructions for installing a plugin here.

If you want to use a different plane than world XY / XZ / YZ , set the construction plane (View > CPlane) before running.

Looks like this:

Simply Great !!!

Thank you Michael. This Section plugin is fantastic.

I'm feeling that this Section plugin is such a wicked addition to MoI that it needs some way of snapping to faces and end points ect and/or a way of being able to apply a percentage or exact dimension to the position of the section.
If I had that, then I could produce all sorts of good stuff such as accurate 2D drawings for my CNC machines.

Thanks.
Martin.

Cool !
What is exactely "Keep geometry" ?

Can we have an option for have a "solid section" even the section is empty ?

Like for a tichkness sphere ?

Hi Pilou,

re:
> What is exactely "Keep geometry" ?

It will keep the stuff that you see as a regular object after the command ends.


> Can we have an option for have a "solid section" even the section is empty ?

I'm sorry I'm not understanding this part, can you show an example?

Thanks, - Michael

I think there is a good spot for a percentage control here:



and I'll experiment with showing a point in the viewport maybe if you drag that you can get snaps.

Thanks,

I don't understand why in case it's a solid section, in the other case that is no solid section ?

It's because the object is malformed by a bug in the shell command in the current v5 beta when making a shell with an internal void.

When you use shell set Library = "Solids++" for right now or select a face to make an opening.

The attached file should work ok.

With your file that working fine!

From my personal try the Shell section is working fine with the Solid ++ and no way with the acis ! (for a simple cube)

In the updated version at the top of this thread, you can type in a percentage or
press the small "point" button to pick a point as alternate ways to position the
section in addition to the slider.

What is the use of this Point ?

---

YES! You're a beautiful man, Michael Gibson. Hopefully everyone gets an efficiency kick out of this!

I'm yet to give it some decent hard testing on the job but looks great so far I'll keep on it!

---

Pilou.
Use the point icon to select a snap point from your model. Your section view will then be in perfect alignment with the point selected.

Michael.

Thank you for adding my suggestions to the Section tool.
It's a brilliant implementation and you have it working just as I'd hoped. ;-)

Martin.

Hi Pilou,

re:

When you push that you can then pick a point on the model and the section cutting plane will pass through that point.

Here is an example using that option to make the plane pass directly through a corner on the model:
