Selecting befoure editing - AutoCAD

What is the setting in Autocad/Autodesk Architectural Desktop 3.3
responsible for such situation. I cant edit/delete selected object. First I
have to choose tool (press button, type), then select objects, then execute
the command. I prefer selecting objects before commands. What setting should
be changed in Tools/Options or what value of witch constant should be set.
Thanks for help.

 

Set PICKFIRST to 1.

 

Just select then use the delete key

 

Thanks, now it is more handy. One more question. Why the same line in Model
Sheet and in Layout Sheet has different look although in Properties there is
the same value of Linetype scale. Is it possible to have the same settings
and effect in both Model and Properties sheets?

 

PSLTSCALE

 

That is what he is trying to do. Won't work if PICKFIRST is set to zero (0).
