Excuse me! To set origin which puzzled me . After finishing setting origin,obj should penetrate grid or not? Thanks.

Hi Atpo, that would depend on where you want to set the origin to. For a piece of furniture, I like having the origin point at the center of the bottom of the furniture. If it's something else, for instance, a sword, I would place the origin point in the handle, because that's where your character would be holding it.

With that in mind, for a piece of furniture, I would place it right on top of the grid, and with the 3D Cursor set to 0/0/0, I would set the origin to "3D Cursor". In the case of the sword, I would place the origin at Center of Mass/Volume, and then the sword would penetrate the grid.

That said, it all depends on what type of object you're modeling, and how you would use it in a scene, that would determine where you want to set the origin point.

Hope that helps.

Thanks B.

You're welcome Atpo.

Hello atpo I agree with all Miss B said and also say consider if the item you are modeling is like a door you would want the origin point set to where you want the door to rotate on a particular axis X, Y or Z also if you are considering to import your model in another application like Daz Studio always before exporting apply the scale and rotation or you will have problems when importing into other applications.

Lobo"I agree with all Miss B ",Lobo love Miss B?Come on man,agree is yes! You love her ,speak aloud to her,don't hide.

Ah gee guys, you're making me blush.

That said Lobo, good point about the rotation axis for doors and such. I hadn't thought of that.

Another important point to note regarding origin is its use when using the mirror modifier, since the mirror is opposite the object origin on any axis.

For example, in Object mode if you create a brand new cube that is placed at the default center origin on the grid.. and then you try to use the mirror modifier.. nothing will appear to happen even if you have all three of the axis selected. This is because the origin of the cube defaults to the center of the geometry and therefore the mirrored cube is directly on top of itself, regardless of its actual location. Now move that cube to the left or right a bit... center the 3d cursor (if it has moved... with "Shift+C") and then press "CTRL+ALT+SHIT+C" and select "Origin to 3D Cursor." By moving the origin of the cube, you have just informed Blender from where to mirror from.

If you are ever having an issue with the mirror modifier, it is important to keep this in mind.

Now that's something I don't do very often, so definitely going to make note of it for future reference. Thanks Erock.

Is there a time limit to editing a post, or can you only edit it once? I noticed a simple typo that I fixed through Edit right after I made my last post. I JUST found another typo though, but I don't see the option to edit it now.

Anyway, I meant "SHIFT", with an "F"! LOL!!

erock3d if you are not the original person who started a thread you only have the one edit option but if it is something that really needs editing you can always contact me and I can usually override and edit the post

Thanks for posting this Erock. Making the change in my notes now. That's what I get for copying/pasting without re-reading.

Thanks erock3d's excellent speech. But you love Miss B ,too.
