MicroStation Lesson-26 Video Lecture - Microstation Tutorials Beginner

let us quickly continue and finish off
this exercise over here we are trying to
draw this particular line from here to
here so the line is tangent at this arc
and over here it is maintaining some
perpendicularity with this particular
line so first let us draw the line being
tangent to this line and to this circle
so you draw a tangent line right click
after which I will select this and I
will extend this over here and this way
extended arbitrarily randomly choose any
point and you extended it after which
you will select the line again from here
you are going to start that you are
going to maintain tangency and then for
this line for this inclined line you
have the condition over here that it is
perpendicular you need to start from
tangency and you need to end it off at
this inclined line with perpendicularity
condition so if you go here
perpendicular option and I will click
over here in this way zoom in and you
can see it clearly
in this way you have created this
portion the only thing remaining is to
trim this off you need to trim this
inner portion that is between this line
press on your control button and this
line after which I'll choose my trim
option select them and click on the
circle you have trimmed it you can also
trim this line as well left click in
order to accept it I can select this
control button select this line as well
trim this arc in this one okay and again
you need to start over here I will come
back to my key points directly got here
from this till here
and till the end point of this line and
see this end point over here
select this line shrim and click on this
circle in this way you have created this
half of the portion you can delete this
okay after creating this next go with
the mirroring option the mirror option
as you have already seen in your
manipulate toolbar is present over here
I'll select this entire figure after
selecting it go with the mirror option
click on mirror and right now it's
coming in this way so I need to choose
vertical about the vertical I want to
mirror it and I'll select it over here
make sure that you check that as you
enable make the option because if you do
not enable this this mirror will be
behaving like your symmetry come out
that is it will delete the right side
portion and only the left side portion
will be created enable make copy and I'm
going to place it over here then left
click in order to accept it or inform it
in this way you have created this figure
the next you can go with the
dimensioning as usual according to the
given figure you can dimension it ok so
that completes this figure in this way
you can proceed along with all these
figures oh here usually whenever you are
given an arc it's better to either use a
fill it
since fill let's are more convenient you
in this draw the arc using the fill
adoption over here here here here
similarly we saw in the previous example
we created fill it's everywhere around
here if at all the filler is not
satisfying the circumstances then you
can go with the circle or the arc option
ok
now after seeing all these toolbars next
we'll go for the hatching the hatching
option the hatch over here is referred
to as the patterns option you have the
patterns toolbar over here and in which
you are going to specify or you are
going to create hatches now I'll draw a
rectangle over here after drawing the
rectangle in the patterns toolbar the
first option over here is hatch area
select the hatch area option and then go
with the selection different methods of
selection element intersection Union
difference flood points etc so I select
the element option and right now you can
see the spacing angle tolerance values
I'll select this rectangle after
selecting that left click to accept the
pattern now you can see the hatch has
been created but the spacing is too huge
the spacing has to reduce in order to
delete the existing hatch I'll close
this you have this option over here
delete pattern select this and click on
this option the pattern gets deleted
select this and this time I'm going to
reduce the spacing to some say 5 the
angle is set to 45 degrees and tolerance
is set to zero now I click on this
rectangle and left click again you can
just click anywhere over here and this
is how you will be getting the harsh
pattern again if you are unsatisfied
select this bleated hatch area search it
to 0.5
in this way you're going to get it now
in case you'd want it the one hatch at
an angle of 45 degrees and one more
hatch overlapping the previous hatch at
some other angle then you can use the
next option cross hatch area that is
right now I am able to only select one
hatch what I'm going to do is I'm going
to delete this and select the second
option and over here spacing 1 and angle
1 spacing 2 and angle 2 are given over
here I'll select the second spacing as
well to 0.5
the batter is element as usual select
this line and left-click now you can see
the difference the first hatch or first
pattern which were created is at an
angle of 45 degrees the next one is at
an angle of 135 or minus 45 degrees that
is your cross hatch area wherein you're
going to create two hatches one hatch
overlapping via the hatch right apart
from this basically these hatches or
patterns when you are going to represent
them in a particular drawing the reason
why you create these hatches whenever
you are going to section a particular 3d
model whatever surface whatever area is
going to come in contact with the
cutting edge it is going to be hatched
that is right now this particular figure
has these portions hatched and the
circle over here the circle over here
the circle over here these are not has
even this rectangle vertical rectangle
over here is not hatched this implies
that in this 3d model whatever 3d
subject object this is it's a housing as
can be seen over here this housing has
this cooler that a cylindrical hole so
here cylindrical hole over here
cylindrical hole four and a vertical
vector
a lot over here when I section this 3d
object I'm going to bring my cutting
edge in order to section it using a
cutting edge right so that cutting edge
is going to come in contact with the 3d
model and only this surface which is has
has come in contact the rest of them are
not going to come in contact with that
cutting edge that is why we generally
use the hatches they help us understand
the object more tle when you create
sections so this is about your hatch
patterns now in depth we are going to
see this select this and delete it sorry
I need to select this option and delete
these hatches ok now when I have one
rectangle over here and one more
rectangle over here in this way now you
can see we have two rectangles and in
the hatch area option we have after
element we have intersection Union
difference etc okay select the
intersection option after which I'm
going to select the first element and
then the second element this is the
intersecting region left click to accept
and then go with your right click
that is the hatch area which has been
created over there in this way you have
has only the intersecting portion I'll
go with undo let us do it again I'm
going with the pattern option selecting
intersection method select this select
this then go with your right click in
order to accept the hatch when you're
selecting the objects you will go with
left obviously and then go with right
click to accept that hatch of course you
can go ahead
select delete option and this time
instead of intersection I'll go with the
Union option select Union select this
rectangle select this rectangle then go
with right click and the together the
common area between the both of them has
been hatched and next I will go with
pausing this session sorry stopping the
session over here we will resume in the
next session
