Attach multiple XREFs in a grid according to filename

[inverso]

Hello,

 

I don't even know if automizing this kind of sequence is possible but I figured it's worth a shot.

 

Right now I got around 600 xrefs to attach to a single file and their names corelate to the position I want them in a drawing. For example I got filenames like "100, 101, 102, 103, 110, 111, 300, 301, 500, 501, 600" and I want them import all of them at once and set them so that whenever first number changes, it begins a new column of attached drawings:

• drawings 100, 101, 102, 103, 110, 111 would one under another in first column,
• drawings 300, 301 would be in second column
• etc.

Is it even possible to create a lisp that would do that?

 

Thank you in advance!

Its doable as you check name as say a number not a string, so can work out via a Cond which column to use. Just thinking do COND backwards.

 

(cond
((> dgwnum 1100)(setq num 11))
((> dgwnum 1000)(setq num 10))
((> dgwnum 900)(setq num 9))
..........
((> dgwnum 100)(setq num 1))
((< dgwnum 100)(setq num 0))
)
