AutoCAD Structural Detailing

[#1]

When I use the Find reinforcement command, ASD moves the view and zooms to empty places... Do you know why?

(I tested that tool in a new drawing with few positions and it works fine, but it doesn't work when I use a big project)...

Anything could be useful.

Thanks!

SCP must be set to World or Universal to work fine... I just realize that...
