Hi,
This problem seems to come on when it feels like. Sometimes in does this and
sometimes doesn't.
Heres the problem. "I can't pick the object on defpoints layer".
Is there a hidden variable thats doing this? Can anyone help???
It is annoying at times.....i really would like to know what's causing this.
Thankyou in advance

Layer defpoints mimics layer 0, if layer 0 is off or frozen, elements on layer defpoints are not selectable.

Also, if defpoints layer is frozen, the objects are still visible, but not selectable.
Not in 2004. If it's frozen, it's invisible like any other layer. It canAlso, if defpoints layer is frozen, the objects are still visible, but not

also be turned off independently of layer 0. But it is still unselectable if
layer 0 if off or frozen.
Hi Tom,
I should have mentioned that I am speaking for 2002 as this is an ambiguous NG "Drafting Techniques". I know OC is also working on 2002.
Ok, mabey I'm missing the point but....
Why would you want to select an object on the defpoints layer anyway?
Definition points are nothing more than the points for dimensions - use grips?
Elements other than dim definition points can be placed on the defpoints layer.
<<Why would you want to select an object on the defpoints layer anyway? >>
ummm... move it, copy it, stretch it, array it, erase it, scale it, basically for the same reasons you'd want to select any other element.
what is it?
and why is in on defpoints?
if its just so that it doesnt plot, then surely it should be on a layer created for that puropse, such a vports, or construction.
I have never ever drawn anything on defpoints.
The OP doesn't say, but I've placed a few things on layer DEFPOINTS for a couple of specific reasons.
Say a bundle pull-zone or a drop zone envelope needs to be reserved so that nothing interferes in the area. A 3DSOLID on layer defpoints won't plot, that’s a plus, but also, when that file is XREF’d into another file, the zone is visible unless the entire XREF is frozen. No one can “accidentally” freeze the drop zone and still work with the XREF.

Well, then you must not have been running Acad for very long. :-)I have never ever drawn anything on defpoints.
The defpoints layer existed for quite a few years before there was any other
available way of making a thing visible but non-plotting. For most of the
history of Acad, if you wanted a non-plotting object, your only option was
to put it on the defpoints layer, you had no other choice. Most people who
have been around Acad for any length of time eventually learned and used
this trick. The non-plotting layer property is a new twist which wasn't
available until just a few versions ago.
Using the defpoints layer is still a valid way of accomplishing this, andif its just so that it doesnt plot, then surely it should be on a layer
created for that puropse
it's still the most convenient way, since the non-plotting layer is already
there -- you don't need to create a special layer for the purpose. For an
isolated object, or for a temporary purpose, there's no reason not to just
pop it on defpoints and move on. For a more elaborate drawing setup, sure,
it can make more sense to organize all your non-plotting elements onto
non-plotting layers.
Also, as OC notes, since defpoints mimics layer 0 in some ways, it's quite
unlikely that an object on defpoints will have its visibility obscured when
the drawing is xref'd into another. Very often, a non-plotting object is one
that is quite important (for coordination, reference, or whatever) and
mustn't be missed or forgotten, but isn't intended to be plotted.
Personally, I've sometimes used this to put a "don't forget!" note to myself
in the drawing file.
We have architect clients who quite regularly use a symbol on defpoints just
to give themselves a point for placing xrefs. Usually they do it when they
have multiple units xreffed into multiple (different) building layouts.
It's very handy for subs and they never have to worry about a reference
layer being turned on after they send drawings out.
