2D drawing doesn't appear correctly

Try changing the view to global or universal hidden line
Rule references need to be looked at as well?

Have you read the manual for draft yet? It will guide you on the basic procedure for creating 2D drawings for instance: -
Setting up views - limits, styles ect
Setting rules - the way lines and shapes are represented
Setting layers - how the hierarchy works
These are fundamental issues that will take too long to explain in messages

 

Navigate to the VIEW and on the command line type Q RRSF.
You should get something like Rrsf /DRA/PRJ/RERP/GEN/BASIC.....
If you get RRSF NULREF....that's the problem

What is the style of View ?

I don't understand your question please.

@ianmp; I've tried both global and universal hidden lines, they all produced the same thing i'm complaining about. How do i access the rule references?
@amunir; please explain what you mean by "style of view"
Thank you.

@ianmp; I've read the manual completely. I generated the drawing in the attached file myself. I just don.t know why the lines are appearing that way.

@corrado; Thank you very much. You're too much. You solved the problem. The problem is i was using /DRA/PRJ/RERP/GEN/PIPE.....,  so i just changed the pipe to basic.
I appreciate.
My next challenge is how to resize the view so i can have about three views in a sheet.
Thanks once again.

I've found the solution to the problem of resizing views. It had to do with resetting the limits. Thanks a lot
