Selecting Objects Issue

[churchill]

Hi guys,

 

Got some strange behaviour on a .dwg I received from a third party a while back that I've just gone to edit. See below screenshot.

 

 

Whenever I go to select one of the single lines, this whole group of objects selects as one, and I can't select down to the individual lines so I can edit them in isolation. It's not a block (see the properties window for the selection), and they're not 'grouped'. I tried an explode and it broke everything down bar 13 lines that 'could not be exploded' (according to the console window). I'm guessing it's maybe an AutoCAD system variable setting or something?

 

TIA!

It's not a block and it's not a group yet you say you used the Explode command on it and got some partial results.

 

What program was used to create the drawing in the first place? Was it an AutoCAD vertical product?

 

Can you attach a copy of the drawing to your next post so we can have a look at it ourselves?

Agree with @ReMark

 

We'll probably need to see the DWG on this one.

I imagine it's behaving to the extent that if you explode a polyline you'll get a load of lines.

 

.dwg available here. I'm unsure of the CAD software that the third party used to create it originally, but you'll find the problematic objects in question at the very top of the model. For ref I'm using ACAD 2011. Cheers guys!

If you click on one of the objects it is identified as a Group consisting of lines, lightweight polylines and a block named "Window". As such you could use the UNGROUP command on it.

 

The block "Window" happens to be the gray polyline rectangle, circle with solid yellow hatch and white letter.

 

You should become familiar with the LIST command and checking PROPERTIES when it comes to identifying entities in your drawings.

Cracking thank you sir! It appears as though the group was unnamed which was probably why I didn't grasp it as being grouped to start with! Just for anyone else's reference, ACAD 2011 doesn't have the UNGROUP command, so I had to go in using GROUP, find unnamed groups, then explode it from within the GROUP dialogue box. Thanks all.

When you exploded it the first time the 13 lines were still a group. That's why you could not edit them individually.

For future reference, don't forget about the LIST command.

 

If PICKSTYLE = 1 or 3, it should have reported any object in the group as being a member of the group.

 

Select objects: 54 found, [b][color="red"]1 group[/color][/b]

Select objects:
                 LINE      Layer: "0"
                           Space: Model space
                  Color: BYBLOCK    Linetype: "BYLAYER"
                  Handle = a9f2
                  [b][color="red"]Group = *A17[/color][/b]
             from point, X=-23947.000  Y=30823.000  Z=    0.000
               to point, X=-17722.580  Y=29499.529  Z=    0.000
         Length = 6363.567,  Angle in XY Plane = 348.00
                 Delta X = 6224.420, Delta Y = -1323.471, Delta Z =    0.000

 

If PICKSTYLE = 0 or 2, then you can select and work with the individual objects even though they are still part of a Group.

 

In this case, the selection will not reveal a group, but it will still be reflected when listing object properties.
