Finalize Sketch | Shapr3D for Beginners

Over the next few lessons, we’re going to
be creating this bracket design. To get started, I’m going to sketch
out the general base shape for this design. I might start with a sketch
that looks something like this. Let’s take a look at how we can create a
sketch like this from scratch. To create the base sketch of the
bracket, I’m going to start by just sketching out those three circles. I’ll
throw one about here, one about here and one about here. What I’d like to do is tap the center point of the first circle and I’m going to throw that
into some location I like. I’d like to move it right on to my origin point and
I don’t necessarily have to do this, this is just a personal preference of
mine, I like to throw it in a location that makes sense to me and a lot of
times that is the origin point. So, when I’m happy with that, I
could then lock this circle in its location. I could just tap that lock
and now I’ve locked the center point of this first circle onto that origin point. I might also want to give a radius value. I’ll tap on the circle and
change the radius value to be 10mm, and then
I would like the other two circles to be the same size, 10mm as well.
Of course I could throw in those dimensions or I could tap all three
circles here, and use the “Equal” constraint. Now let’s finish off some of
the locations of those circles. I’ll tap on the center point to move this
into place on this X-axis. The upper
circle maybe somewhere here for now. I’m going to finish that off
with some dimensions. From my origin point to the center point of my
bottom circle, I’ll give that a distance dimension of 50mm. Now I have that locked in 50mm away on that X-axis. If I’d
like, I could lock that location in as well if I’m happy with that location, and
do the same with the top circle. I’ll just measure the distance
between these two center points in my circle. Let’s say I am looking for
the absolute, I’ll tap on that distance. I have the ability to give
absolute dimension, horizontal or vertical dimensions. But I am going to
look for an absolute dimension and make it 50mm. Then I’ll tap
the two center points on these two circles here, and give the same 50
mm distance. So now my third circle center point should be locked in
as well, just from the constraints and dimensions. But if I’d like, I could
tap the lock icon to lock that in as well. Now, we’ve fully defined all the
size and locations of these three circles. Next, I might just throw in some
arcs, somewhere about here, somewhere about here and somewhere about here. Notice I might not make the arcs perfect in this case, I’m just going to get them
close to where I’d like them, and now I can throw in some tangent relationships
to help finish it off. For example, this arc and this circle, I’d like to be
tangent, same with that same arc and this bottom circle, tangent. Just the
same with my bottom arc, bottom circle, tangent and bottom arc with the other
bottom circle tangent and so on. Now I can see I’m getting pretty
close to my final sketch. I might just want to throw in some radius values
of these arcs, I can tap on my bottom arc there, and I’m gonna give
this a radius of 50mm again. Finally, perhaps I’d
like the radius of all three arcs to be equal, so I’m gonna tap to select all
three of my arcs and use the equal constraint. Now I’ve pretty much
finished off this bracket base sketch and I might just want to clean it
up a little bit using the trim tool, I can just tap on the trim tool and trim away any of these sketch segments I may no longer need.
Any of these ends of arcs I can be trimmed away to help clean up the
sketch a little bit. Now we can see we have a somewhat complicated sketch,
which will be used to generate our 3D bracket component. And in the next few
lessons we will be learning how we can use this sketch to create 3D designs.
