Autodesk 123D beta 9 Offset -Trim Feature Video Lecture | Autodesk 123D: A Complete Course - Design Softwares

now let's look at some of the other
sketch options we've got let's look at
the offset feature what that does it it
copies your current sketch and you can
scale it either up or down so let's
click on sketch notice it turns blue
notice now how if I go inside my sketch
I've copied that exact same sketch or
shape in words or i can go outwards and
what i'm doing is i'm just scaling up
that sketch it's a really handy tool
because it saves me a lot of time having
to redraw that shape again especially if
you are after an identical scaled up
version of your sketch also notice how
now that I've done that I have this
little pill shape tool by that appears
and some of the things that you can are
quite handy that you can find here you
can cut and copy and you can move rotate
and scale see if i click on move rotate
and scale you can select in a line and
you can move a particular line like so
or you can click on a point and you can
just move a point so it's quite handy so
that's the offset tool let's look at now
the trimmed option so in order for us to
do that let's create a circle and then
let's create a polygon like so now if we
click right click sketch trim what this
does is you can two shapes that are
interceding with one another you can
start to choose to eliminate particular
lines that are intersecting with one
another so in this case we can remove
the line that's going through the
polygon like so or we can remove the
other side of this circle art so now
we've just got a semicircle art you can
do similarly to the polygon so we can
remove and trim all these other lines so
now we've created a totally new shape
just by using circles and polygons it's
quite handy sometimes you've got to be
really smart and how you're going to
create your sketch it's a lot quicker if
you use a trim tool than having to draw
each arc individually and draw this
shape individually it's better just to
use existing shapes and then using the
trim tool
