- Planar surfaces are pretty straightforward
and all we really need to do is tell SOLIDWORKS
which edges we want to use to go ahead and create a surface.
To get started let's go up to planar surface up here,
and it's asking me for the bounding entities.
You have a little q here showing you it's looking
for one enclosed boundary.
So I can chose this sketch right here,
I can choose an edge itself
and notice it chooses the automatic boundary,
and just that quickly,
I create a surface just using that little
square or rectangle there.
Then I can also come over here and do it again
under planar surface,
I can choose an interior edge here
and fill in the holes, for instance.
It's only a surface here so you look at the bottom,
you can still see it's an open hole.
Or if you come over here I have a bunch of surfaces here,
I again can go back over to surfaces, planar surface,
and I can choose individual edges here.
As I go around this,
notice it stars filling it in and I just chose those two,
and then with a triangle,
but I can continue my way around
and as soon as I have an enclosed boundary,
it tries to fill it in.
But I can also take islands or remove pieces
from the center of it.
So you see here I've got an enclosed boundary,
but if I go ahead and I add in these edges here,
all the way around,
make sure you're choosing the top edge.
As soon as I've done that it excludes that from the surface.
Same thing over here with this top of the circle,
I can go ahead and do that and then fill it in.
Now I have this one as a solid body here,
this one as a surface body with a clear added top
to the top there.
I also have the option if I wanted to
to go to planar surface,
I can just choose lines, like a line here
and maybe a line right here.
And it will fill in a surface between those two.
And that works just fine as well.
So a lot of cool ways to create surfaces just using
a planar surface.
It's pretty basic,
all you really need to do is tell it
which edges you want to use.
And you don't even need to give it all the edges,
a couple edges works just fine.
In fact, you can even just use a line and a point
if you want to create something like a triangle.
