PRACTICAL 3 – BASIC ELEMENTS OF MICROSTATION – 2D

OBJECT: To understand the basic commands of Microstation for circular fillets,

chamfering, and filling with colours in certain specific zones.

Learn line, smart line (for filling colours), angle bisector, modify element and B-spline

(open curve and close curve), group commands.

Duration: two turns

1. Draw a polygon, and draw a circle inside it. Then fill the area except the circle

with red colour and then change it to green.

2. Determine the net area of the polygon without that of the circle.

3. In the above problem, fill the circle in blue colour and the rest of the outer area

within the polygon with red colour.

4. Chamfer the corners of the polygon with different radii.

5. Draw a rectangle and modify the corners with fillets.

6. Draw a line. Draw another line perpendicular to it at its mid point.

7. Draw a line and draw another line at a given angle and at a give position on this

line.

8. Bisect this angle in the above problem. Mark the dimension of the angle.

9. Draw B-spline curves by defining control points. Try various available options.

Fill the curve with different colours.

10. Draw an ice cream cone with double scoop ice cream. Show ribs as in an ice

cream cone.

OBJECT: To understand the basic commands of Microstation for making a 3D element

– cuboid, sphere, cylinder, cone, and frustums.

Hint: Open a 3D seed file.

Learn extrude, construct union, divide, intersect, cut solid, remove faces and heel

commands.

Duration: two turns

1. Draw a rectangle and extrude it to obtain a cuboid.

2. Draw a circle and extrude it to obtain a cylinder.

3. Draw an inclined line and rotate it to obtain a cone and a frustum.

4. Determine the volume of each of the above 3D elements.

5. Draw a polygon and extrude it to obtain a prism.

6. Draw a circle and extrude it to obtain a cylinder and cut a cylindrical hole through

it.

OBJECT: To understand the basic commands of Microstation for making a 3D element

and cutting with a plane and taking projections.

Hint: learn projections, feature, modifier, cut hole

Duration: two turns

1. Draw a cone and cut it with a horizontal plane. Separate the two parts.

2. Draw a cylinder and cut it with an inclined plane. Separate the two parts.

3. From a point in space, draw a perpendicular to a given plane. Find the length of

this perpendicular.

4. Draw a cylinder inclined at an angle of 30o with horizontal. Take its projections

on x-y, y-z and z-x planes. Verify using the principles of Engineering Graphics.
