Course 1: Using Lines
In this course, you will learn how to use lines with constraints. You
will be able to create objects such as:
First
start MINOS and create the current view. For that you need to
change the current view into a front view. Go to the [View
Management] [Create Immediate View] [Front] menu.
 |
To create straight lines, use the [Lines] [Segment Placement]
menu.
Define the
horizontal base segment through the [Create a
segment with 2 point] menu. For the
horizontal segment, type [N] for numerical
coordinates, and enter "X0,Y0,Z-30" and
"DY10". The segment is created. For the
vertical segment, type [N], then enter
"X0,Y-30,Z0" and "DZ10". The
segment is created.
Create the
parallel segments. Select the [Create a
segment parallel to another] menu. Locate the
horizontal segment, click on the top of the view
to indicate the position, and enter the distance
by typing "60". Locate the vertical
segment, click on the right of the view, and
enter "40". The parallel segments are
created.
Then, you
need to define a segment with an angle. Select
the [Create a segment tangent to a circle with
an angle] menu. Select the [Passing thru
constraint] button at the bottom of the
screen, and [Passing Thru Intersection]
near it. Then, click on the intersection of the
two segments. For the angle, enter "70"
for 70 degrees. The segment is created.
All the segments are created !
|
| To create circles, you need to create constraints like these. |
 |
 |
The first
circle, must be defined at the intersection of two
segments and tangent to another. Therefore, select the [Lines]
[Circle Placement] [Create a circle with center and a
point] menu. For the center, select the [At
the intersection of two lines] yellow button at the
bottom of the screen. And pick the first and the second
segment.
For the point,
select the [Tangency constraint] button at the
bottom of the screen and select the segment with an
angle. The circle tangent to this line is created.
|
| You need to
create fillets. Then, select the [Lines] [Circle
Placement] [Create a circle tangent to 2 elements with
radius] menu.
Create a
first circle tangent to the circle and the upper
horizontal segment. For that, select the [Tangency
Constraint] button at the bottom of the
screen. And click the circle and the segment.
Enter the radius by typing "5". Note
that the result depends on the position of the
click.
Proceed in
the same way for the other circles.

You will now
use a very powerful function of MINOS: The Contour
Function Select the [Lines] [Create a
complex string with support elements] menu. Now, you
can create the "Contour" by clicking a way on
the segments and the circles. Note the different results
according to your choice. Each time you are lost, you can
push the [Delete] key to step back. When you are
on the first element, you can click on [OK] to
close the contour.
Erase all the construction lines by using the [Display Last Element]
menu at the lower right side of the screen.
|
| You are now ready to create a solid.
You need
for that to change the current view into an
axonometric view. Go to the [View Management]
[Create Immediate View] [Axonometric] menu.
Go to the [Solid and surface placement] [Create a cylinder]
menu.
Select the
contour. Create an edge vector by clicking on an
arbitrary point, and entering the coordinate by [N]
for numerical coordinates, and enter
"DX20" to define the translation
vector.
