Entity Coordinate Systems Video Lecture | TurboCAD: A Complete Course - Design Softwares

hi this is rip with IMSI design and
today I'm going to be talking about
coordinate systems specifically entity
coordinate systems so what we have here
is three circles and they all - all
appear to be on the same work plane
let's say I'm gonna switch to a left
view and you don't see something above
or below everything seems to be one
solid line of going across so it looks
like everything's on the same work plane
but they are not all three of these
circles in fact have different
coordinate systems and we can see this
by activating the grid and then
selecting with the 2d selector tool so
you can see my selector is in 2d mode
and when I select this circle I get this
warning message selecting the object in
2d mode changes the drawings workplane
do you want to continue I'm going to say
yes and since the grid follows the
current coordinate system you can see
the grid has shifted slightly in this it
is rotated so I'm gonna select this
circle same warning message yes to
continue
and this one's rotated a little bit
differently as well then I'm gonna
select this circle which just happens to
be on the world coordinate system and
the grid looks how you'd expect a grid
to look so there's three things
how do objects end up with different
coordinate systems how do we fix this
problem by putting them all giving them
all the same coordinate system and then
how do we prevent it from happening in
the future
so first off this is a feature and
there's there are reasons why you would
want to have different coordinate system
have these entities have different
coordinate systems and use different
coordinate systems in the 2-d selector
for instance if you have if one of these
circles was on the face of a cube and I
just wanted to move it along that face
it would be very useful to have the
coordinate system switch to be that of
the 2d object but that's just one
example for most people it actually is
kind of a huge headache because they do
it inadvertently and they go to trim
something and they've turned off all the
warning messages they're not using the
grid they go to trim something or join a
poly
and they get some error about entities
having different coordinate systems
they're like what are you talking about
I'm just working in 2d this is crazy so
so let's go over kind of how this
happens and how to fix it
so how this happens is I'm going to go
ahead and draw another circle and then
I'm it happens when you edit an entity a
2d entity using the 3d selector so I'm
gonna switch to the 3d selector I'm
gonna rotate this now here we go editing
the selected 2d object in the 3d mode
changes the object's work plane to set
the work plane use the place on work
plane option from the modify menu so
it's basically telling you that it's
changing the object's work plane we use
the word work plane and coordinate
system kind of interchangeably here it's
a little confusing
albeit so now I'm gonna switch I'm gonna
deselect I'll switch to the 2d select
tool now when I select it ah my grid
shifted again so what I want to do is I
want to switch to the 3d select tool
select all modify place on work plane
now I can switch back to the 2d selector
select any of these entities and I can
do anything with them in the coordinate
system does not change so one way of
preventing the this from happening is to
when you're working in 2d to do is have
the 2d selector on you know there's
times when I kind of like to have use
the 3d selector when I want to move
objects left and right if I want to use
all these fancy handles on the 3d
selector so you can do that you just
have to work in safe UCS mode so if you
go to selector 3d properties turn on
safe UCS mode now I can move rotate
moving around used these nice handles I
can stretch it rotate some more and when
I switch to the 2d select tool
everything stays just like it's supposed
to be so to make a long story short if
you use safe UCS you won't run into any
problems with 2d entities thank you very
