Topic: Why snap not working with insertion point of nested block?

[HasanCAD]

I created this block with array(attached).
this morning I was able to snap to insertion point of nested block, But now I can not.

[ChrisCarlson]

I don't think you can? The insertion point of that block Wall-RFT-150-WO-STRG is the bottom left.

I was able to snap to the nested block (Cyan circle ) but now can not.

[mjfarrell]

why do you want to?

perhaps a vis state that only shows that nested block?

This DB showing the bars (for plan section detail - we drafting structural design drawing) I add this blocl then add stirrup (It id as DB too).

I cannot snap to it either. if you kept a circle around the hatch in the 'SS' block definition you could snap to center.

Redefine block SS to be a donut (pline) with a center radius of 0 and a diameter of 1, and you can snap to center.  the osnap to insert is snapping to the insertion of the whole block not the nested.  I have never been able to osnap to a nested insert for anything except text.

OK that is good temper solution. Working fine.
But I want to know the reason of that.

As I said, I have never been able to osnap to a nested insertion point for anything except text.  Osnap INSertion will find the insertion point of the whole dynamic block, how would it ever know you were looking for a nested insert??

(That said you can toggle GRIPS for nested elements on and off with GRIPBLOCK)

[mjfarrell]

Why wouldn't you want to snap to any object ?

Instances where that particular object should not be used as a grip and or alignment entity.

[HasanCAD]

Is it mean I was dreaming!?!?!?

Building a block that has objects to snap to is a plus in my book. If you don't want to snap to them then press F3 (unless your snaps are already off LOL ). 

Just because you don't wish to snap to PARTS of a block doesn't mean you don't wish to snap to other parts, besides F3 is ONLY running OSNAP and does nothing for 'real' OSNAP. 

[mjfarrell]

no, he is saying one could STILL use snap overrides even IF OSNAP is toggled OFF with the F3 key

I don't understand what you're talking about. Are you agreeing with me?

no not really, you seem to indicate that if one doesn't wish to OSNAP to a particular point on a block one should just turn off OSNAPPING all together (F3)

[RC]

Isn't that kind of a 'DUH' statement? Seems like if you enter a snap mode, you know what you want to snap to. Anyhoo .. I've had enough chat about snaps .. carry on. 

and therein lies my point, F3 has nothing to do with it

instead of pline I draw a line with length 0 mm in insertion point of block. I believe it is better to snap

[ChrisCarlson]

Well all plines have a minimum of two end points and a midpoint. Depending on your point settings you could easily use a point at the insertion point of SS and add it to your array / stretch group.
