Use case is 3D printing, which often has issues with hollow interiors, especially when scaled down. Miniatures from full size leads to thin walls and failed prints. Make the model solid and the slicer with create infill as desired and the miniature will print well.

Thank You!!! I have just taken up 3D printing again but now with a resin printer. One of the things I have been trying to print is a 12 scale doll using MakeHuman. The problem I had is that the exported file has cavities for eyes and mouth and when I hollow out the model in my slicer it just adds walls around them with no way to drain the resin trapped inside. I'm not very savvy when it comes to Blender and you wouldn't believe the number of different terms I have done searches for trying to find the answer to my problem or the amount of time I've spent searching - I have learnt a few things I didn't know, so the searches were not entirely fruitless :-) So again thank you.
@notverygoodguy Жыл бұрын
I am glad this has helped and I do know the problem you have! If I use a generated model from makehuman, charmorph or mb-lab I usually remove the teeth and tongue at least if the mouth is closed and it isn't always easy. I haven't found eye cavities an issue though. I think makehuman had an option to not include the mouth parts though I might have just mis-remembered that.
@OzTwinmum Жыл бұрын
@@notverygoodguy so unfortunately, your solution didn't work because the cavities are not enclosed cavities at all - they are just caves so to speak from the front of the model, even with a closed mouth, there is a minuscule gap and the eyeballs don't seal off the eye sockets. Back to trying how to add a solid shape into the holes :-( But I still think I need to bookmark this video for future uses.)
@notverygoodguy Жыл бұрын
@@OzTwinmum You might try just going mesh->cleanup->fill holes. This often works for me when there is an open mouth. Alternatively, select faces on the back of the head and hide them with "h". You can then just remove the mouth cavity fairly easily. At this point you either join the top and bottom lip or boolean a ball or somthing in there. Of course you need to unhide the faces you hid with ALT H afterwards. I would say that you can also drill resin draining holes through the entire head and then gluing the hair on top after wards :) With all that said, if you generate your character with charmorph, the mouth will print fine and the resin will drain out if you do nothing at all.

I understand your pain here. It must be quite frustrating. The difficulty here would be that in many cases I don't know what the actual function is and I guess many people are the same. H is easy enough I guess as it hides the selection but I don't know what that is actually called in the key map. Even worse for things like p. Internally I associate that with seParate but I am pretty sure that isn't the correct name. I like your idea but am not sure how I would achieve it.

The use case is for 3D printing models that are hollowed, but are small so adding holes will only cause significant damage to detail without really allowing you to remove the excess resin.

What does the action L do? Hitting L doesn't seem to select anything for me. When I just select the model by clicking on it, it all disappears when I hit H to hide. It's hiding the entire model and I'm not left with anything to delete. I can see shapes inside the model when I turn on X ray and when I slice it there are weird gaps inside that show up as solid on some layers that print but not others so I'm sure there's something odd going on inside this model.
@notverygoodguy10 ай бұрын
L will select everything that is connected to the vertex under the mouse pointer. H will hide everything selected. I would guess that your inside wall is connected to the outside walls somewhere so when you press L, it is also selecting those inside the model. If this is the case, you could try manually selecting all the outside vertices by using the circle select tool by pressing c and then adjusting the size of the tool with your mouse wheel. Then brush all over the outside of the model. Be careful as it is easy to miss some. Then when you have selected everything you can see, you can press H. If you are having problem, post a link to your blend file and I'll have a quick look.

@notverygoodguy9 ай бұрын
This can be a little more difficult but you might be able to do it this way. Making sure X-Ray mode is off you can select everything you can see by using the circle select option, press c and then use the mouse wheel to increase the size of the selection circle and then go round your model selecting everything you can see. Because you don't have X-Ray mode on it shouldn't select any inside vertices. Then invert the selection ( turn on X-ray to check it has now selected the insides) and just delete the selected vertices. I'd be interested to know if this actually works for you.

@@julianopolito You are skilled enough that you diagnosed correctly why the method in this video wasn't working for you. Seems to me your only option is to select as much as you can with the circle select tool as described and then hide what you have selected by pressing h. This will then make it possible to see and select the more difficult to get at vertices. Keep selecting outside vertices and hiding them until you are left with just the inside of your model. Then turn x-ray mode on and select everything remaining which should be the inside of the model until you have selected everything. Delete the vertices and then do alt-h to unhide all the outside vertices you selected earlier. You'll need to be careful and have a copy of your model first and you might need to fill up some small holes afterwards (use Mesh->Clean up->fill holes) but this will work in principle even if it does take a bit of time. Also make sure you have face orientation on as described in the video so you can see a little easier which vertices to select.

Assuming you are not select everything with "a" instead of using "l" you could be very unlucky. If you have a model where the inside touches the outside somewhere this method wont work. What you could try although it would be a bit more annoying is to select all of the vertices manually using the circle select tool or the other selection tools. Then when you are sure you have them all selected, duplicate them with SHIFT D, press the left mouse button and then go p->by selection. This will give you a second but solid version of your model. If your models it complex it could be tough to be sure you have all the outside vertices selected though. Please let em know if you continue to have problems with this.

Firstly are you sure it's actually hollow? A Blender object by default is solid and so you have to actually make it hollow on purpose. There are several ways in which a model may look hollow in other software e.g. a printer slicer with no infill selected but that doesn't mean it actually is. Are you able to share a link to your blend file or model, maybe using wetransfer.com or google drive or similar? I would be interested to have a look at it.

This case is more difficult as you would need to fill in the holes. One suggestion that comes to mind would be to ensure all the parts are put together in object mode so they make up the completed model. Then join them with CTRL J. Next, in edit mode you need to select all the outside vertices. This might be difficult depending on the model but as a last resort you could select them with the circle select (press c and the use the mouse scroll wheel to adjust the size of the circle) and then just go p->by selected. Then you should have an object of just those selected vertices.
