Autocad 2013 - select a polyline by value in attribute

[marcolanna83]

Hi everyone,

I am currenty dealing with a question for a project I am working on. I have a complex building, in which all rooms are described by a tag. The tag is a block which contains as attributes several kinds of information about that room (height, finishing, etc.). One attribute is the surface of the room, which is linked to a polyline by a field (if the polyline changes, the surface attribute changes consequently.

Now, basing on the fact that there is a correlation between my block containing the attributes and the polyline (the correlation is given by the surface field), I would like to select polylines in my drawing basing on specific values in my attributes block. Example: I want to select all the polylines which are linked to the blocks containing as an attribute the text "1.1.1.1.1", or the polylines linked to a block containing as an attribute the text "library".

This would save me loads of time to generate some specific drawings.

Despite not finding anything looking around, I am sure I am not the first person having this question, thus I hope a solution is already available! Any help would be highly appreciated.

The three comamnds built into LT to select similar items are:
SELECTSIMILAR (available with a right-click, settings/options can be controlled by SELECTSIMILARMODE explained in HELP).
QSELECT
FILTER

See this classic tip on how to do what I think you want, an attribute in a block (it uses Properties to launch QSELECT command but you don't have to):
