Is there a way to find the centre of an object?
Trying to find the centre of an object to try and sculpt a wheel with spokes. Guessing the middle is a bit hit and miss. Managed to work around it with the kaleidoscope tool but the effect isn’t right.
Would be good to know the middle of an object when trying to attach strings to floating platforms too.
Not at the moment. However it’s possible to create sculpts which centres are on the grid.
While in Sculpt Mode, tweak the shape with Shift+Square, select the Grabbing Point mode in the palette, and select the central grabbing point of your shape which looks like a 3D cross.
Now the Imp will be grabbing the sculpt from its centre. This will allow you to place it right on a Grid point, therefore letting you find that center again when using the Grid.
