group command/extend trimm command not working

[BITDRAUGHTY]

Hello there ,

I am having some problems with my autocad and it seems to be that something has become turned off somewhere.

In the extend command if i extend to a line then hold down shift to start the trim command it will not trim.It says lines does not intersect.if i then start the trim command it will trim straight away ??

Also my group command has stopped working.Named or unnamed nothing will group.If i select then items and right click to group at the command line it claims to have done it .....but it has not.

Likewise if i start the named group command and select the items etc giving them a name nothing happens.....they are still seperate entities.

Can anybody help please.....

Thank you

B Draughty

What version of AutoCAD are you using?

From the AutoCAD 2004 Help file:

"You can select groups by name at the Select Objects prompt. If the PICKSTYLE system variable is set to 1 or 3 and you select any member of a selectable group, AutoCAD selects all group members that meet the selection criteria. You can also toggle group selection on and off by pressing CTRL+H or SHIFT+CTRL+A."


PICKSTYLE
Controls the use of group selection and associative hatch selection.

0 No group selection or associative hatch selection
1 Group selection
2 Associative hatch selection
3 Group selection and associative hatch selection

By the way, have you checked to see what the system variable Edgemode is set to?

EDGEMODE
Controls how the TRIM and EXTEND commands determine cutting and boundary edges.

0 Uses the selected edge without an extension
1 Extends or trims the selected object to an imaginary extension of the cutting or boundary edge

All this information can be found using AutoCAD's Help.

Thank you, i had rememberd the edgmode command late last night but had not resolved the group command which is now resolved .

I am aware that it is in the help files i also have the bible sitting here on my desk(not the religious type) but unless you know that command it does not necessarily come up under the group command.

Thank you

In Help, if you search on Group, one of the choices presented is Groups (of objects) and under there you'll see toggling group selection. If you open that subject you'll notice that Pickstyle is mentioned. Sometimes we can't find the tree because it's hidden in the forest. Not too worry though, even with my one good eye I've managed to overlook quite a few trees in my time. No offense meant.
