Handle and Centre Co-ordinate Extract LISP

[Lee Mac]

...and others may suspect me of being the worst LISP coder ever.

 

More likely suspect me of focussing too much on the finer details...

 

Anyway, consider this alternative:

 

'(
   (-4 . "<OR")
       (-4 . "<AND")
           (0 . "LWPOLYLINE")
           (-4 . "&=")
           (70 . 1)
       (-4 . "AND>")
       (-4 . "<AND")
           (0 . "POLYLINE")
           (-4 . "&=")
           (70 . 9)
       (-4 . "AND>")
   (-4 . "OR>")
)

No worries; only being jovial.

 

I originally used 1 & 9, but this excluded my "L" shaped polyline... further investigation revealed this entity (the "L") was 129. This prompted me to make the quick change to 'not' 0.

But find three deference output

That's true, but is easy for OP, as long he/she had the desired information in electronic form, to edit it to the right format.

Hmmm... I thought Lee's was working perfectly - except it's not listing the centroid for the polyline that the handle belongs to! Handle X is next to the centroid for polyline Y....

[ClareSelley]

Renderman: Thanks for yours - that's actually better & works perfectly.

That is kind of you to say, but if you're wanting to use my code, I must insist on revising it to utilize the Centroid Property coordinate value of a region, rather than using the Centroid of the BoundingBox (the bottom left, and upper right). My original code was left intact (originally) for others to learn from my mistake. I will revise the code momentarily.

Code revised here.

Looking back at my code, I can't see anything that would cause this to happen; furthermore, after a quick test, the code appears to function correctly for me.

Lee: It may well me me messing up somehow. It just didn't run right for me for some reason! Thanks for your help!

HI,

 

please help me to mark circles in error layer from selected handles in .csv file

[MSasu]

Can you post an excerpt from that CSV file? Also, what do you understand by marking them?
