Measuring distances in ZBrush

…ZBrush was not made with 3D printing in mind.…It wasn't even originally made with 3D modeling in mind.…For this reason, ZBrush's unit and measurement systems are not well-equipped…to handle the task of making things with precise real-world scale.…However, since real-world scale is paramount to 3D printing.…We need to find a way to make…Z-resh measure things accurately and consistently for us.…Let's take a closer look at some measurement challenges and solutions.…

So we've got a model and we want to measure how big it actually is.…Now for this we can use any of the transpose tools.…These are the move, scale, and rotate.…You can just click on any one of these, or hit W, E, or R on your keyboard.…And you'll get this manipulator and you can…click and drag this out any way you want.…But I want to, put this from top to bottom.…And this is going to snap onto whatever part of the model we click on.…So if we rotate around you can see it snapped to where we touched here and here.…You can make sure it comes out in a straight line, if you hold down Shift.…
