Hi there, my name is An, i'm with Creaform, and in this feature video, I shall demonstrate
how to properly use the Fill Holes function
in VXmodel. It is located under the Improve
section of the toolbar, in the top middle
of the screen. So let's begin with a little
definition. What is a hole? A hole is characterized by an open boundary, like the pink highlights you
see here. Most likely, we were not able to
penetrate these areas with our scanner due
to a number of reasons. As you may know, 3D printing requires that you have a watertight stl
for the best results, meaning there should
not be any leaking holes in your scan data. And
that's why the Fill Holes function is probably the most used tool in VXmodel. So let's dive
right in because there are a few things that I would like to show you. There are three main
modes inside of Fill Holes. There's Whole,
Partial and Bridge. I will start with the
default mode called Whole. It is a point-and-shoot operation. Simply highlight the boundary which
you like to fill and click on it. Or, you
also have the option for multi-select. Here,
I'm selecting the first 20 boundaries and
I can fill them all in with a single click
of a button. They are listed based on increasing boundary length.
smallest, followed by the next one, and the next one. In the last one will be
the largest. There are three filling methods that we can play with here. Experiment and
see which one gives better results. Low and high curvatures are used for shapes with a
natural curve. Flat is generally used for a
flat feature like the bottom of this block. The
option for smooth boundary layers will go back and potentially change the mesh prior to the
boundary. Leaving it at zero will maintain
the integrity of the boundary, whereas any
other values will result in a different shape. 
Now, let's move on to the second Fill Hole mode:
Partial. Sometimes an open boundary may run in multiple different directions making it
impossible to fill in just one go. This is
where Partial comes in handy. Simply click
on the first point, the last point, and the
point in the middle shall determine the direction.
Lastly there's Bridge. It is used to connect
two separate boundaries together. Or it can
also be done on the same boundary. Click on the first point, last point, and middle point
on the first side followed by the first point, last point, and middle points on the other
side. Then we have a bridge that connects the two sides together. And there you have it. Thanks
for watching. And if you find this video helpful, please remember to Like and Subscribe for future videos
