Drawing polyline from the block

(1/3) > >>

antistar:
Hi to all,
I ask a great help to teachers.
I have a block with 4 tags for length, thickness, elevation and width.
Could anyone help me write a routine to capture the data from these tags and draw the closed polyline + 2 internal lines, parallel to the block?
It would be possible to change the dimensions of the drawing whenever I change a tag?

Block Name: ID_DATA
Tags: LEN, THI, ELE and WID.

Thanks in advance.

Lee Mac:
The creation of the Polyline based on the block attribute information could certainly be achieved, (this function will help you in that respect); however, the automatic updating of the Polyline dimensions based on the attribute information would be rather complicated, likely requiring the use of reactors.

Ok Lee,
 Thank you for your attention and explanation.
 I understand the complexity of using reactors. The reactors will leave to another step.
 Could you help me create a polyline with the attribute information?

Post the code that you have started and I'll offer hints and tips  :-)

Applying his subroutine LM: GetAttributes, I got the following list:

 ((LEN. 140) (THI. 120) (ELE. 100) (WID. 14))
