Leader DXF code for Arrow size

Hi,

I would like to automatically edit the arrow size of a leader after it's insertion in a drawing with a specific program.

What is the DXF code associate to it and wich way I can reach it trough the DXF code of that kind of entity ?

Thanks

Marcel

 

I would like to automatically edit the arrow size of a leader after it's insertion in a drawing with a specific program.

There's a couple ways. You could manually edit the block definition that
is referenced by the leader and edit it that way. However, I believe
(could be wrong) that modifying (mirror, scale, stretch, etc) the leader
will update it to it's default dimstyle defined setting.

The other way is by applying an DimStyle Override to it. This can be
cone via the (command) or you should be able to do it via DXF codes be
placing the proper data in Xdata for that leader.

Haven't tested any of this recently so the behavior I explained could be
different but last time I played with this type of thing (years ago), I
believe this was the case.

Although the Arrowheadsize can be accessed and edited with standard lisp and
DXF codes, it is a REAL pain to do.
However, using vlisp & activex it is easy.

Vlisp method, assumes you already have the <ename> of the leader stored as
'ent':

(setq ldrobj (vlax-ename->vla-object ent))
(vla-put-arrowheadsize ldrobj 0.15)

I won't go into the DXF method other than to say you need to check if the
ent has xdata related to dimensions already attached. If there is, add the
codes for dimasz. If not the xdata must be created and the codes for dimasz
added to it.

HTH,

I always forget about ActiveX from Lisp. Old habits die hard I guess.
