AutoLisp - Selection set and blocks

I am trying to get a selection set of an existing block at a certain location. Something like:

(ssget "C" pt1 pt2)

But the crossing points are located on a pline of the block and it does not return a SS. Is there another way to accomplish this?

Using AutoCad 2002.
Thanks

(ssget "x" (list (cons 0 "INSERT")(cons 10 blockinspt)))

not return a SS. Is there another way to accomplish this?

 

The window and crossing parts of the ssget function only work if the object is visible in the AutoCAD display limits. I'll bet if you do a zoom extents before running your ssget, it will select the objects your looking for.

 

hulioman,

It worked........ thanks for your help.

Another words it you can't see the window or crossing (similar to the stretch command, when you pan the display outside or past your first selected crossing point) autocad for some reason cannot see that point location?

A window or crossing will only select entities that are both within the points provided AND at least partially visible onscreen. SSGET "X" will grab all entities in the database, including ones that are offscreen, on frozen layers, etc.

One undocumented option I found a few years back is SSGET "all". SSGET "a" also works. It acts just like when you enter "all" at a selection prompt on the command line. It grabs everything in the drawing whether or not it's currently showing on screen, but unlike "x", it excludes nonvisible entities such as entities on frozen and turned off layers and blocks that are in the database but not inserted in the drawing. Pretty handy...
