Hi Michael,

Say : for sure this helps a lot ! :-D

Thank you very much for your time taken to work on my file and to answer me.
This helps me a lot also with my understanding of MoI. (How to use Rebuild function with shortcuts or tab&typing, re-make point curves etc.)

Strange : yesterday I was sure to have checked the lack of this small surface on the top of the half-cylinder without seeing any kind of surface...
Anyway maybe I was too tired, so today is a very good day with its good news :-)

Again thank you very much for your excellent help.

Best Regards,

< That will fill in an end cap in that planar opening of the object, sealing it off and making it into a solid now

!!!
Never seen seen that!!! I was selecting each edges of a future face! :)
here a simple click on one face of the object make the trick :)

So in fact Planar is an automatic close volume engine !

Hi Pilou,

But yes you have! :) Because didn't you translate the reference for Planar here which describes it and shows an example too? :

:)

But yes, it's a shortcut - if you select an entire surface object instead of selecting curves you can then run Planar and it will find sets of open edges that make planes, then construct the planes there and join them in to seal them off, so it combines a few steps doing it that way.

Yes i did indeed :)

but don't realised that for one simple rectangular face in a box no need to select the "4 sides" of the hole against just click an adjacent face one!

Now that is fixed in my mind ! :)

Hi Pilou - you don't need to select any individual faces at all actually, you just select the whole object with just one click so the whole thing is selected and then run Construct > Planar. Any planar openings will get sealed up.

- Michael

Yes only one click on one face if the object is boolean unioned like the model of this thread ;)

And the "4 sides" if by hasard you want in your model just one hole face planed ;)

So many possible combinaisons
