Is there a way to hollow a cube to segments so it would be grid aligned and have it still look like a cube as if I hollowed it by percentage?
Or is there a way to hollow it by percentage and have it grid aligned?
Ofcourse I can then edit the cube and have the result I want but do I really need to edit every room I make like that?

This is not what I want:


I want something like this just grid aligned:


Thanks !

hollow it with merged and the the percentage = 0

Do you mean segemented or merged hollowing? If segmented, ou can set the segment depth to the grid size you're using.

Also, the word is "hollow"

first create the outer cube, then create an cube and move it in the other cube as you want the walls of your room, then select all the face's of the inner cube and click on flip, now merge the both cube's but if you don't want them to be one object then don't merge.

OK here is how you do it.

1. With snapping on (double click the word snap to make dark on bottom indicator if not already)

2. Create your box, all corner vertexes will be snapped to grid.

3. Click on hollow in Low Polygon Editing box.

4. Click radio button Merged and enter your percentage in box e.g 80

5. Click OK

6. Inner surface created. But not snapped to grid ( dont't worry )

7. Make sure object still selected, should be at this stage still unless you click any where on screen. Click Object Tab on Right panel.

8. Look down list to where it says Snap method on left , word on right will be 'none' click this.

9. Click little arrow to drop down selection box and click on the word vertex

10 . click in active screen.

11. Smile as now inner box has snapped to grid .

Always looks a lot more comlicated when wrote down than when you actually do it. takes just a second.

This is bad geometry. You shouldn't ever have surfaces touching like that. If you want a proper hollow room. Make a cube and reverse the normals. Then you have an inward pointing room.

DeleD is not a brush editor.

It would be possible to write a plug-in that did just what you want, which is often known as "thicken walls" or "hollow inset." However, it would be even easier for the DeleD folks to write that as a command, because they already have CSG functions built.

The process could be made much simpler if someone wrote a plug-in that duplicated the selection, flipped the faces, then moved the faces in the direction of the face normal by one quantum. Keep track of which direction each face wants to push each vertex, and push each vertex by the sum of all movements. This would create the inside. You could then just use this as the inside, or you could merge the objects.

Note that the above algorithm is not robust in the case of very narrow shapes (smaller than 3 units).
