If clause linked to block's attributes

[k.tsolidis]

Hello everyone,

I have a lot of blocks with attributes and I am exporting them in a spreadsheet. Through this procedure, I am able to change my data (attribute’s insertions) simultaneously to a lot of blocks and import it again to my .dwg file (express tools->import attributes).

I was wondering, if there is any possibility, when I import the new attributes from the excel file, to have something like an if clause running in my drawing, for Example: “If attribute’s value is _____ then change block's color to _____” or “If attribute’s value is _____ then replace block _____ with _____”

Is there any other way to achive the above?

I don’t know many thinks about scripts, so any information would be helpful,
Thank you in advance.

That could be done with a custom command.  One way to do that would be to use AutoLISP.

David_W._Koch Thank you for your response.

I would appreciate it if you could show me how to do it!

I don't really know how to write this specific "IF" command, as well as I am not familiar to AutoLISP.

Thank you in advance

Can you provide an example drawing to show what you have and what you need.

Also include some information on when what should be changed.
