VariCAD 2016 English - Lesson 40/49 - Constraints in Solid Creation Video Lecture | VariCAD: A Fundamental Training - Design Softwares

hello all we are here for one more
lesson of this body card 2016 training
course and the topic for this lesson is
constraints in solid creation basically
I want to show you how to constraint
profiles in 2d and that way how can we
influence and constrain the solids so I
will start to make a very easy solid as
usual so just making a rectangle and a
hundred in X 15 y very easy shape and
I'll make some feelings for example 5 5
and I would make a radius somewhere
around here 10 something like this now
this is a very normal profile and normal
to the entities no constraints so now I
will extrude it can be printed that it
really does not matter I will select the
profile and say the insertion point is
around here so extrusion done so I have
my solid I have no constraints the
profile was perfectly normal and it is
now when I go to the function to edit
the solid that I can insert my
constrains in terms of that to the
entities so indeed the system recognizes
that this solid was made from a 2d
profile so confirm and when I have this
toolbar here I
this function that says define
constraints or parameters okay and now I
enter in these it's not a special mode
but it's this look where I get this
toolbar that's solid profile constraints
where I can insert the constraints in
terms of the points so I have a couple
of possibilities I will show you the
main concepts and these four start icons
2 for X and 2 for y represent these
constraining something in X Direction
relative to the center of coordinates
and this regarding an object and the
same for the other axis so for example
constraining to the center of
coordinates I will open a selection
window so I get these two points the
vertices just say the okay and I can
select one of the vertices to say that
one and okay he knows that I'm a hundred
millimeters away in X from the center of
coordinates and as before when we see
the constraining in the last lesson I
already mentioned for a couple of times
that the interesting part of the
constraining is to connect this with
parameters okay because this will allow
you to change your model very easily and
you can connect these with mathematical
expression that besides the idea of just
changing your model you can have these
relations that change your model on a
way that you can predict okay so I'll
say for example linked
and just save you okay and he
understands that I have I have not this
parameter
so created and the parameter is done
okay I can go back and now I can say the
other option constraining an object
regarding an object so I can constrain
this vertex here and I can say regarding
this point here for example and okay you
understand that is this distance I can
say length a for example okay sorry I
cannot sorry linty I cannot put that
symbol I have this value I can change it
and say for example 30 and go back and I
could do the same on the other direction
it's the same no need to do it just do
the okay confirm and rebuild my model so
the interesting part of this now is if
you come in this parameter table
now you can come and say I want to
change this I want to put for example 80
millimeters and apply the changes and
your model reacts as you expect okay
but we can do other kinds of
constraining and I can constrain also
beside the Shaffers m and the art and so
on
I can constrain for example radius and I
can do something like saying I want to
constrain this radio here and I can say
or let us start for this first sorry and
I can say radius and he knows that has
10 on the value created and I can
constraint also this one and say radius
divided by two and saying for example
this one and Ray years divided by three
for example okay and just apply the
changes and again if you go to the
parameters now you have some relations
on these entities basically if you
change this value for example let us put
a bigger value I hope it allows you this
really okay this okay and you see the
complete model was changed with this
addition so this is very easy to work
with and if you see here you can have a
couple of more addition possibilities
which are radial constraints regarding
the center of coordinates or regarding
an object it is the same concept that we
use here for example for a quick example
I can do something like this
the vertex regarding the center of
coordinates for example let us say a
bigger value and go back and just to the
okay and it will make this kind of thing
okay I could put a parameter also the
the possibilities are very are quite
open to to do this
and we can have these also regarding a
redefinition of the coordinate system I
will not show you this this is a little
more confusing so I will not share this
information with you at this moment and
for the ones that think this may be
interesting for them please contact us
or check our theoretical part because
it's a little confusing at this moment
to to show you here we can also edit an
existing constraint for example I could
edit this and change the conditions and
here I can delete the constraints
display the constrains what we have so
basically these are informations check
the dimensions of the profile and these
are display modes identical to functions
we've seen in one of the previous
lessons for the sketch mode ok shaded or
by frame and have these contours or
profiles thick or thin so a couple of
things addition of the profile set these
extrusion height without changing the
constraining and go back and change ok
this is quite easy to understand and
there is any more topics to understand
regarding the constraints in 2d
basically and I will finish this lesson
with one strong idea which is if you
compare this kind of constraining that
you have in Barakat it's very different
from the majority of the other softwares
in the market because you see that you
can constrain what you want you don't
have the obligation to consider
everything to have a very rigid profile
so you can just constraint one element
half of the half of your profile
whatever you want so this is very easy
very open and very flexible which in my
personal opinion it is one of the big
advantages of Vericut regarding other
systems and in most of the case much
more powerful and expensive system so
this is very easy the idea and if you
understand the concept of this you can
take this very far away and having your
profiles and in consequence your solids
also very flexible in every stage of
your design process
