STEP BY STEP
SCALE ON AN IPAD FOR 3D PRINTING
01 OPEN A DEFAULT CUBE
To start the process, go to the Scene menu and add a cube. A cube will be created in the centre of the scene and if you look down the menu to the Box Geometry option, you will see that it starts with a dimension of 1,1,1. This means that if you exported it now, you would get a 1mm-sized cube. You can check or uncheck the Same-size-cube option to change the size proportionally.
02 SCALE THE SHAPE
If you are making a miniature figure, you may want to have a 50mm base and the figure might need to be 70mm high. Type 50, 50 and 70 into the relevant boxes and the cube will scale to that size. You can then validate it to make it editable, although you won't be working on the cube again; it is simply a reference tool.
03 SCULPT YOUR MODEL TO SIZE
Set the material on the cube to Blending and lower the opacity so it becomes a reference model only. Now you can make your sculpt inside those defined parameters. Turn off the visibility as you need if it is getting in the way. I imported a model I had already made and scaled it to the 70mm height. The hand sticks out of the sides so you can really see how this can help when designing a character.
04 EXPORT TO SLICER AT SCALE
Export the model either as an OBJ or STL and then go to your slicing software of choice. I used Pikaslice on the ipad here. Import the model and you will see it is scaled perfectly, and in most cases it will be in the correct orientation. If not, simply use the rotation tools before you move to supporting and slicing.
